Supplementary Figure 1 Electron density sequence and structure analysis

(a) Stereo representation of experimental 2|Fo|-|Fc| electron density maps

(blue) after solvent flattening in SHARP 1 contoured at 1σ Electron density

for the four gold atoms that were used to phase the structure in SIRAS

experiments is shown as yellow anomalous difference map contoured at 10σ

The refined model of TRABID is shown as a ribbon coloured in orange for the

AnkUBD and blue for the OTU domain (b) Sequence alignment for the

crystallized constructs of human (Hs) mouse (Mm) and Drosophila

melanogaster (Dm) Trabid and human A20 OTU domain Boxed residues are

similar and residues on a solid background are identical and colours are blue

for the AnkUBD and red for the OTU domain Secondary structure elements

are indicated and labeled according to Fig 1c above for TRABID and below

for A20 The sequence alignments were prepared with T-coffee

(httptcoffeevital-itchcgi-binTcoffeetcoffee_cgiindexcgi) and coloured

with ESPript (httpespriptibcpfrESPriptESPript) (c) Structure and

superposition of the Ub complex of Crimean Congo Hemorrhagic Fever Virus

(CCHFV) OTU domain (vOTU) (pdb-id 1phw 2) and TRABID The left image

shows the vOTU~Ub complex with vOTU in green and Ub drawn as a yellow

surface The right image shows a superposition in the same orientation and

coloring as in Fig 2d

Supplementary Methods

Cloning and mutagenesis

For bacterial expression TRABID AnkOTU (245-697) and Ank (245-339)

constructs were cloned into the pOPIN-K vector that comprises an N-terminal

PreScission-cleavable GST tag using the Infusion 20 Technology (Clontech)

Point mutants were generated by site directed mutagenesis using the

QuikChangereg technology (Stratagene) For mammalian expression full-

length TRABID (2-708) full-length TRABID NZF mutant 3 TRABID AnkOTU

(245-708) TRABID OTU (339-708) full-length TRABID ΔAnk (Δ249-338)

were subcloned into pCMV-3xFLAG (Stratagene) using EcoR1Xho1 sites

For immunofluorescence full-length TRABID (2-708) TRABID AnkOTU (245-

708) TRABID OTU (339-708) were subcloned into pEGFP-C1 using

Xho1EcoR1 sites GFP-tagged TRABID constructs 2-200 2-345 FL-TRABID

ΔAnk (Δ249-338) TRABID Ank (245-345) as well as all other Ank mutants

used in this study were obtained by using the QuikChangereg technology

pEGFP-Cezanne wt 4 was used to derive pEGFP-Cezanne C194S

Protein purification for biochemical biophysical and structural studies

All protein purifications were performed at 4degC TRABID AnkOTU (245-697)

and OTU (339-697) constructs were expressed in Arctic Xpress cells

(Stratagene) Cells were induced at an OD600 of 06-08 with 150 microM IPTG

and grown overnight at 16 degC Cells from 6 L culture were lysed by sonication

in 50 ml lysis buffer (270 mM sucrose 50 mM Tris [pH 80] 1 mM EDTA 1

mM EGTA 10 mM sodium β-glycerophosphate 50 mM sodium fluoride 10

mM β-mercaptoethanol 1 mM benzamidine 01 mg mL-1 DNAse 1 1 mg mL-1

lysozyme) and cleared by centrifugation The cleared lysate was incubated

with 4 ml equilibrated glutathione-S-sepharose 4B resin (GE Healthcare) for 1

h and subsequently washed with 50 ml lysis buffer 500 ml buffer A (25 mM

Tris [pH 85] 1 mM EDTA 5 mM DTT) plus 500 mM NaCl and 500 ml buffer

A plus 150 mM NaCl The GST-tag was cleaved on the resin with 50 microg GST-

tagged PreScission protease overnight Cleaved protein was diluted to ~50

mM NaCl with 25 mM Tris (pH 85) and subjected to anion exchange

chromatography (MonoQ 550 GE Healthcare) where it eluted as a single

peak in a NaCl gradient from 50 to 500 mM

For crystallography peak fractions were pooled and subjected to gel filtration

(Superdex75) in buffer B (200 mM NaCl 25 mM Tris [pH 82] 1 mM EDTA 5

mM DTT) The protein was concentrated to 35 mg ml-1 using a VivaSpin 10

kDa MW cut-off concentrator and used in crystallization screening

TRABID Ank domain constructs were expressed in Rosetta2 pLysS cells and

were lysed and incubated with glutathione sepharose as described above

Crystallisation data collection phasing and refinement

The TRABID AnkOTU structure was determined from crystals grown at 23degC

from 150 mM NaCl 100 mM NaOAc 5 mM MgCl2 50 mM MES [pH 59] For

synchrotron data collection crystals were soaked in mother liquor containing

275 ethylene glycol and frozen in liquid nitrogen To obtain phase

information crystals were soaked in 1 mM KAu(CN)2 for 1 h prior to freezing

Diffraction data on the AnkOTU crystals were collected at the ESRF

(Grenoble) beamline ID23-2 Crystals displayed space group P212121 with

one molecule of AnkOTU in the asymmetric unit A native dataset collected to

225 Aring resolution and a peak wavelength SAD dataset at 3 Aring resolution from

AuCN soaked crystals were used for phasing using single isomorphous

replacement with anomalous scattering (SIRAS) An initial set of sites was

obtained with the SHELXhkl2map suite 5 and site refinement was performed

in SHARP 1 Density modification within SHARP resulted in a high-quality

map which was interpreted by WarpNTrace and manually rebuilt in Coot 6

Refinement was performed using PHENIX 7 including simulated annealing

and TLS B-factor refinement Final statistics can be found in Table 1

NMR titration analysis

For titration experiments HSQC spectra were recorded for 50 microM TRABID

alone and in presence of 250 microM and 1 mM unlabeled Ub For the reverse

experiment spectra were recorded for 50 microM of 15N-labelled Ub alone and in

complex with varying concentrations of unlabeled TRABID Ank domain either

wild-type or bearing point mutations (H317A I320D L332E) Separate

samples were prepared for each measurement such that no adjustment was

required to account for dilution with increasing volume For chemical shift

mapping weighted chemical shift perturbations were measured in 15N fast-

HSQC experiments 8 and defined as D1H + (D15N5) [ppm] 9 To obtain

approximate KD values by NMR peak frequencies (either 1H or 15N

whichever varied greatest in the titration) for nine representative correlations

were plotted as a function of the concentration of unlabeled protein at four

different concentrations and fitted to a quadratic expression for binding

equilibria as described

(httpstructbiovanderbilteduchazinwisdomkdcalchtm) KD values were

obtained by least squares fitting of the experimental data to trial curves

varying in the simulated KD Quoted KD values are the median of values

obtained for the nine peaks

Photobleaching experiments

FRAP (fluorescence recovery after photobleaching) experiments in COS-7

were carried out as described previously 10 Briefly cells were seeded onto

Lab-Tek II chambered cover-slides (Nalgene Nunc International Rochester

NY USA) 24 h before transfection Next 100 ng of GFP-TRABID constructs

were transfected using lipofectamine and photobleaching was conducted 18

h post transfection GFP puncta were bleached with five maximum-intensity

scans with the 488 and 514 nm lines of a 40 mW argon laser (Zeiss

AXIOVERT 200M inverted confocal microscope) Fluorescence recovery was

monitored in images taken during the following 60 seconds The fluorescence

intensity was normalized to the mean fluorescence intensity of the whole cell

(DAPI stain middle image) The right image shows a merged picture

Inactivated Cezanne does not form a punctate pattern like TRABID (b)

Selected cells from co-transfection experiments with FLAG-Ub variants and

GFP-C443S which have only been transfected with FLAG-Ub but not with

GFP-FL C443S are shown in absence (as in Fig 7e) or presence of

proteasome inhibitor MG132 Red color indicated the Cy3-labeled anti-HA

staining while blue indicates a DAPI staining showing the cell nucleus All Ub

variants express and are diffusely distributed across the cytoplasm and no

significant changes are seen upon proteasome inhibition Different intensities

result from different overexpression levels (c) Co-localization of GFP-TRABID

FL C443S with FLAG-Ub wt performed as in Fig 7e but in presence of

MG132 (d) Co-localization of HA-TRABID FL C443S (left) with GFP-FL ΔAnk

C443S (second from left) A DAPI stain reveals nuclei (second from right)

and the merged image is shown to the right The localization of the HA-tag

was performed as for the FLAG-tag using a rat anti-HA antibody (Roche) and

a Cy3reg goat anti-rat IgG (Invitrogen)

Supplementary Methods

Cloning and mutagenesis

For bacterial expression TRABID AnkOTU (245-697) and Ank (245-339)

constructs were cloned into the pOPIN-K vector that comprises an N-terminal

PreScission-cleavable GST tag using the Infusion 20 Technology (Clontech)

Point mutants were generated by site directed mutagenesis using the

QuikChangereg technology (Stratagene) For mammalian expression full-

length TRABID (2-708) full-length TRABID NZF mutant 3 TRABID AnkOTU

(245-708) TRABID OTU (339-708) full-length TRABID ΔAnk (Δ249-338)

were subcloned into pCMV-3xFLAG (Stratagene) using EcoR1Xho1 sites

For immunofluorescence full-length TRABID (2-708) TRABID AnkOTU (245-

708) TRABID OTU (339-708) were subcloned into pEGFP-C1 using

Xho1EcoR1 sites GFP-tagged TRABID constructs 2-200 2-345 FL-TRABID

ΔAnk (Δ249-338) TRABID Ank (245-345) as well as all other Ank mutants

used in this study were obtained by using the QuikChangereg technology

pEGFP-Cezanne wt 4 was used to derive pEGFP-Cezanne C194S

Protein purification for biochemical biophysical and structural studies

All protein purifications were performed at 4degC TRABID AnkOTU (245-697)

and OTU (339-697) constructs were expressed in Arctic Xpress cells

(Stratagene) Cells were induced at an OD600 of 06-08 with 150 microM IPTG

and grown overnight at 16 degC Cells from 6 L culture were lysed by sonication

in 50 ml lysis buffer (270 mM sucrose 50 mM Tris [pH 80] 1 mM EDTA 1

mM EGTA 10 mM sodium β-glycerophosphate 50 mM sodium fluoride 10

mM β-mercaptoethanol 1 mM benzamidine 01 mg mL-1 DNAse 1 1 mg mL-1

lysozyme) and cleared by centrifugation The cleared lysate was incubated

with 4 ml equilibrated glutathione-S-sepharose 4B resin (GE Healthcare) for 1

h and subsequently washed with 50 ml lysis buffer 500 ml buffer A (25 mM

Tris [pH 85] 1 mM EDTA 5 mM DTT) plus 500 mM NaCl and 500 ml buffer

A plus 150 mM NaCl The GST-tag was cleaved on the resin with 50 microg GST-

tagged PreScission protease overnight Cleaved protein was diluted to ~50

mM NaCl with 25 mM Tris (pH 85) and subjected to anion exchange

chromatography (MonoQ 550 GE Healthcare) where it eluted as a single

peak in a NaCl gradient from 50 to 500 mM

For crystallography peak fractions were pooled and subjected to gel filtration

(Superdex75) in buffer B (200 mM NaCl 25 mM Tris [pH 82] 1 mM EDTA 5

mM DTT) The protein was concentrated to 35 mg ml-1 using a VivaSpin 10

kDa MW cut-off concentrator and used in crystallization screening

TRABID Ank domain constructs were expressed in Rosetta2 pLysS cells and

were lysed and incubated with glutathione sepharose as described above

Crystallisation data collection phasing and refinement

The TRABID AnkOTU structure was determined from crystals grown at 23degC

from 150 mM NaCl 100 mM NaOAc 5 mM MgCl2 50 mM MES [pH 59] For

synchrotron data collection crystals were soaked in mother liquor containing

275 ethylene glycol and frozen in liquid nitrogen To obtain phase

information crystals were soaked in 1 mM KAu(CN)2 for 1 h prior to freezing

Diffraction data on the AnkOTU crystals were collected at the ESRF

(Grenoble) beamline ID23-2 Crystals displayed space group P212121 with

one molecule of AnkOTU in the asymmetric unit A native dataset collected to

225 Aring resolution and a peak wavelength SAD dataset at 3 Aring resolution from

AuCN soaked crystals were used for phasing using single isomorphous

replacement with anomalous scattering (SIRAS) An initial set of sites was

obtained with the SHELXhkl2map suite 5 and site refinement was performed

in SHARP 1 Density modification within SHARP resulted in a high-quality

map which was interpreted by WarpNTrace and manually rebuilt in Coot 6

Refinement was performed using PHENIX 7 including simulated annealing

and TLS B-factor refinement Final statistics can be found in Table 1

NMR titration analysis

For titration experiments HSQC spectra were recorded for 50 microM TRABID

alone and in presence of 250 microM and 1 mM unlabeled Ub For the reverse

experiment spectra were recorded for 50 microM of 15N-labelled Ub alone and in

complex with varying concentrations of unlabeled TRABID Ank domain either

wild-type or bearing point mutations (H317A I320D L332E) Separate

samples were prepared for each measurement such that no adjustment was

required to account for dilution with increasing volume For chemical shift

mapping weighted chemical shift perturbations were measured in 15N fast-

HSQC experiments 8 and defined as D1H + (D15N5) [ppm] 9 To obtain

approximate KD values by NMR peak frequencies (either 1H or 15N

whichever varied greatest in the titration) for nine representative correlations

were plotted as a function of the concentration of unlabeled protein at four

different concentrations and fitted to a quadratic expression for binding

equilibria as described

(httpstructbiovanderbilteduchazinwisdomkdcalchtm) KD values were

obtained by least squares fitting of the experimental data to trial curves

varying in the simulated KD Quoted KD values are the median of values

obtained for the nine peaks

Photobleaching experiments

FRAP (fluorescence recovery after photobleaching) experiments in COS-7

were carried out as described previously 10 Briefly cells were seeded onto

Lab-Tek II chambered cover-slides (Nalgene Nunc International Rochester

NY USA) 24 h before transfection Next 100 ng of GFP-TRABID constructs

were transfected using lipofectamine and photobleaching was conducted 18

h post transfection GFP puncta were bleached with five maximum-intensity

scans with the 488 and 514 nm lines of a 40 mW argon laser (Zeiss

AXIOVERT 200M inverted confocal microscope) Fluorescence recovery was

monitored in images taken during the following 60 seconds The fluorescence

intensity was normalized to the mean fluorescence intensity of the whole cell

Supplementary Methods

Cloning and mutagenesis

For bacterial expression TRABID AnkOTU (245-697) and Ank (245-339)

constructs were cloned into the pOPIN-K vector that comprises an N-terminal

PreScission-cleavable GST tag using the Infusion 20 Technology (Clontech)

Point mutants were generated by site directed mutagenesis using the

QuikChangereg technology (Stratagene) For mammalian expression full-

length TRABID (2-708) full-length TRABID NZF mutant 3 TRABID AnkOTU

(245-708) TRABID OTU (339-708) full-length TRABID ΔAnk (Δ249-338)

were subcloned into pCMV-3xFLAG (Stratagene) using EcoR1Xho1 sites

For immunofluorescence full-length TRABID (2-708) TRABID AnkOTU (245-

708) TRABID OTU (339-708) were subcloned into pEGFP-C1 using

Xho1EcoR1 sites GFP-tagged TRABID constructs 2-200 2-345 FL-TRABID

ΔAnk (Δ249-338) TRABID Ank (245-345) as well as all other Ank mutants

used in this study were obtained by using the QuikChangereg technology

pEGFP-Cezanne wt 4 was used to derive pEGFP-Cezanne C194S

Protein purification for biochemical biophysical and structural studies

All protein purifications were performed at 4degC TRABID AnkOTU (245-697)

and OTU (339-697) constructs were expressed in Arctic Xpress cells

(Stratagene) Cells were induced at an OD600 of 06-08 with 150 microM IPTG

and grown overnight at 16 degC Cells from 6 L culture were lysed by sonication

in 50 ml lysis buffer (270 mM sucrose 50 mM Tris [pH 80] 1 mM EDTA 1

mM EGTA 10 mM sodium β-glycerophosphate 50 mM sodium fluoride 10

mM β-mercaptoethanol 1 mM benzamidine 01 mg mL-1 DNAse 1 1 mg mL-1

lysozyme) and cleared by centrifugation The cleared lysate was incubated

with 4 ml equilibrated glutathione-S-sepharose 4B resin (GE Healthcare) for 1

h and subsequently washed with 50 ml lysis buffer 500 ml buffer A (25 mM

Tris [pH 85] 1 mM EDTA 5 mM DTT) plus 500 mM NaCl and 500 ml buffer

A plus 150 mM NaCl The GST-tag was cleaved on the resin with 50 microg GST-

tagged PreScission protease overnight Cleaved protein was diluted to ~50

mM NaCl with 25 mM Tris (pH 85) and subjected to anion exchange

chromatography (MonoQ 550 GE Healthcare) where it eluted as a single

peak in a NaCl gradient from 50 to 500 mM

For crystallography peak fractions were pooled and subjected to gel filtration

(Superdex75) in buffer B (200 mM NaCl 25 mM Tris [pH 82] 1 mM EDTA 5

mM DTT) The protein was concentrated to 35 mg ml-1 using a VivaSpin 10

kDa MW cut-off concentrator and used in crystallization screening

TRABID Ank domain constructs were expressed in Rosetta2 pLysS cells and

were lysed and incubated with glutathione sepharose as described above

Crystallisation data collection phasing and refinement

The TRABID AnkOTU structure was determined from crystals grown at 23degC

from 150 mM NaCl 100 mM NaOAc 5 mM MgCl2 50 mM MES [pH 59] For

synchrotron data collection crystals were soaked in mother liquor containing

275 ethylene glycol and frozen in liquid nitrogen To obtain phase

information crystals were soaked in 1 mM KAu(CN)2 for 1 h prior to freezing

Diffraction data on the AnkOTU crystals were collected at the ESRF

(Grenoble) beamline ID23-2 Crystals displayed space group P212121 with

one molecule of AnkOTU in the asymmetric unit A native dataset collected to

225 Aring resolution and a peak wavelength SAD dataset at 3 Aring resolution from

AuCN soaked crystals were used for phasing using single isomorphous

replacement with anomalous scattering (SIRAS) An initial set of sites was

obtained with the SHELXhkl2map suite 5 and site refinement was performed

in SHARP 1 Density modification within SHARP resulted in a high-quality

map which was interpreted by WarpNTrace and manually rebuilt in Coot 6

Refinement was performed using PHENIX 7 including simulated annealing

and TLS B-factor refinement Final statistics can be found in Table 1

NMR titration analysis

For titration experiments HSQC spectra were recorded for 50 microM TRABID

alone and in presence of 250 microM and 1 mM unlabeled Ub For the reverse

experiment spectra were recorded for 50 microM of 15N-labelled Ub alone and in

complex with varying concentrations of unlabeled TRABID Ank domain either

wild-type or bearing point mutations (H317A I320D L332E) Separate

samples were prepared for each measurement such that no adjustment was

required to account for dilution with increasing volume For chemical shift

mapping weighted chemical shift perturbations were measured in 15N fast-

HSQC experiments 8 and defined as D1H + (D15N5) [ppm] 9 To obtain

approximate KD values by NMR peak frequencies (either 1H or 15N

whichever varied greatest in the titration) for nine representative correlations

were plotted as a function of the concentration of unlabeled protein at four

different concentrations and fitted to a quadratic expression for binding

equilibria as described

(httpstructbiovanderbilteduchazinwisdomkdcalchtm) KD values were

obtained by least squares fitting of the experimental data to trial curves

varying in the simulated KD Quoted KD values are the median of values

obtained for the nine peaks

Photobleaching experiments

FRAP (fluorescence recovery after photobleaching) experiments in COS-7

were carried out as described previously 10 Briefly cells were seeded onto

Lab-Tek II chambered cover-slides (Nalgene Nunc International Rochester

NY USA) 24 h before transfection Next 100 ng of GFP-TRABID constructs

were transfected using lipofectamine and photobleaching was conducted 18

h post transfection GFP puncta were bleached with five maximum-intensity

scans with the 488 and 514 nm lines of a 40 mW argon laser (Zeiss

AXIOVERT 200M inverted confocal microscope) Fluorescence recovery was

monitored in images taken during the following 60 seconds The fluorescence

intensity was normalized to the mean fluorescence intensity of the whole cell

GFP-FL C443S are shown in absence (as in Fig 7e) or presence of

proteasome inhibitor MG132 Red color indicated the Cy3-labeled anti-HA

staining while blue indicates a DAPI staining showing the cell nucleus All Ub

variants express and are diffusely distributed across the cytoplasm and no

significant changes are seen upon proteasome inhibition Different intensities

Supplementary Methods

Cloning and mutagenesis

For bacterial expression TRABID AnkOTU (245-697) and Ank (245-339)

constructs were cloned into the pOPIN-K vector that comprises an N-terminal

PreScission-cleavable GST tag using the Infusion 20 Technology (Clontech)

Point mutants were generated by site directed mutagenesis using the

QuikChangereg technology (Stratagene) For mammalian expression full-

length TRABID (2-708) full-length TRABID NZF mutant 3 TRABID AnkOTU

(245-708) TRABID OTU (339-708) full-length TRABID ΔAnk (Δ249-338)

were subcloned into pCMV-3xFLAG (Stratagene) using EcoR1Xho1 sites

For immunofluorescence full-length TRABID (2-708) TRABID AnkOTU (245-

708) TRABID OTU (339-708) were subcloned into pEGFP-C1 using

Xho1EcoR1 sites GFP-tagged TRABID constructs 2-200 2-345 FL-TRABID

ΔAnk (Δ249-338) TRABID Ank (245-345) as well as all other Ank mutants

used in this study were obtained by using the QuikChangereg technology

pEGFP-Cezanne wt 4 was used to derive pEGFP-Cezanne C194S

Protein purification for biochemical biophysical and structural studies

All protein purifications were performed at 4degC TRABID AnkOTU (245-697)

and OTU (339-697) constructs were expressed in Arctic Xpress cells

(Stratagene) Cells were induced at an OD600 of 06-08 with 150 microM IPTG

and grown overnight at 16 degC Cells from 6 L culture were lysed by sonication

in 50 ml lysis buffer (270 mM sucrose 50 mM Tris [pH 80] 1 mM EDTA 1

mM EGTA 10 mM sodium β-glycerophosphate 50 mM sodium fluoride 10

mM β-mercaptoethanol 1 mM benzamidine 01 mg mL-1 DNAse 1 1 mg mL-1

lysozyme) and cleared by centrifugation The cleared lysate was incubated

with 4 ml equilibrated glutathione-S-sepharose 4B resin (GE Healthcare) for 1

h and subsequently washed with 50 ml lysis buffer 500 ml buffer A (25 mM

Tris [pH 85] 1 mM EDTA 5 mM DTT) plus 500 mM NaCl and 500 ml buffer

A plus 150 mM NaCl The GST-tag was cleaved on the resin with 50 microg GST-

tagged PreScission protease overnight Cleaved protein was diluted to ~50

mM NaCl with 25 mM Tris (pH 85) and subjected to anion exchange

chromatography (MonoQ 550 GE Healthcare) where it eluted as a single

peak in a NaCl gradient from 50 to 500 mM

For crystallography peak fractions were pooled and subjected to gel filtration

(Superdex75) in buffer B (200 mM NaCl 25 mM Tris [pH 82] 1 mM EDTA 5

mM DTT) The protein was concentrated to 35 mg ml-1 using a VivaSpin 10

kDa MW cut-off concentrator and used in crystallization screening

TRABID Ank domain constructs were expressed in Rosetta2 pLysS cells and

were lysed and incubated with glutathione sepharose as described above

Crystallisation data collection phasing and refinement

The TRABID AnkOTU structure was determined from crystals grown at 23degC

from 150 mM NaCl 100 mM NaOAc 5 mM MgCl2 50 mM MES [pH 59] For

synchrotron data collection crystals were soaked in mother liquor containing

275 ethylene glycol and frozen in liquid nitrogen To obtain phase

information crystals were soaked in 1 mM KAu(CN)2 for 1 h prior to freezing

Diffraction data on the AnkOTU crystals were collected at the ESRF

(Grenoble) beamline ID23-2 Crystals displayed space group P212121 with

one molecule of AnkOTU in the asymmetric unit A native dataset collected to

225 Aring resolution and a peak wavelength SAD dataset at 3 Aring resolution from

AuCN soaked crystals were used for phasing using single isomorphous

replacement with anomalous scattering (SIRAS) An initial set of sites was

obtained with the SHELXhkl2map suite 5 and site refinement was performed

in SHARP 1 Density modification within SHARP resulted in a high-quality

map which was interpreted by WarpNTrace and manually rebuilt in Coot 6

Refinement was performed using PHENIX 7 including simulated annealing

and TLS B-factor refinement Final statistics can be found in Table 1

NMR titration analysis

For titration experiments HSQC spectra were recorded for 50 microM TRABID

alone and in presence of 250 microM and 1 mM unlabeled Ub For the reverse

experiment spectra were recorded for 50 microM of 15N-labelled Ub alone and in

complex with varying concentrations of unlabeled TRABID Ank domain either

wild-type or bearing point mutations (H317A I320D L332E) Separate

samples were prepared for each measurement such that no adjustment was

required to account for dilution with increasing volume For chemical shift

mapping weighted chemical shift perturbations were measured in 15N fast-

HSQC experiments 8 and defined as D1H + (D15N5) [ppm] 9 To obtain

approximate KD values by NMR peak frequencies (either 1H or 15N

whichever varied greatest in the titration) for nine representative correlations

were plotted as a function of the concentration of unlabeled protein at four

different concentrations and fitted to a quadratic expression for binding

equilibria as described

(httpstructbiovanderbilteduchazinwisdomkdcalchtm) KD values were

obtained by least squares fitting of the experimental data to trial curves

varying in the simulated KD Quoted KD values are the median of values

obtained for the nine peaks

Photobleaching experiments

FRAP (fluorescence recovery after photobleaching) experiments in COS-7

were carried out as described previously 10 Briefly cells were seeded onto

Lab-Tek II chambered cover-slides (Nalgene Nunc International Rochester

NY USA) 24 h before transfection Next 100 ng of GFP-TRABID constructs

were transfected using lipofectamine and photobleaching was conducted 18

h post transfection GFP puncta were bleached with five maximum-intensity

scans with the 488 and 514 nm lines of a 40 mW argon laser (Zeiss

AXIOVERT 200M inverted confocal microscope) Fluorescence recovery was

monitored in images taken during the following 60 seconds The fluorescence

intensity was normalized to the mean fluorescence intensity of the whole cell

Supplementary Methods

Cloning and mutagenesis

For bacterial expression TRABID AnkOTU (245-697) and Ank (245-339)

constructs were cloned into the pOPIN-K vector that comprises an N-terminal

PreScission-cleavable GST tag using the Infusion 20 Technology (Clontech)

Point mutants were generated by site directed mutagenesis using the

QuikChangereg technology (Stratagene) For mammalian expression full-

length TRABID (2-708) full-length TRABID NZF mutant 3 TRABID AnkOTU

(245-708) TRABID OTU (339-708) full-length TRABID ΔAnk (Δ249-338)

were subcloned into pCMV-3xFLAG (Stratagene) using EcoR1Xho1 sites

For immunofluorescence full-length TRABID (2-708) TRABID AnkOTU (245-

708) TRABID OTU (339-708) were subcloned into pEGFP-C1 using

Xho1EcoR1 sites GFP-tagged TRABID constructs 2-200 2-345 FL-TRABID

ΔAnk (Δ249-338) TRABID Ank (245-345) as well as all other Ank mutants

used in this study were obtained by using the QuikChangereg technology

pEGFP-Cezanne wt 4 was used to derive pEGFP-Cezanne C194S

Protein purification for biochemical biophysical and structural studies

All protein purifications were performed at 4degC TRABID AnkOTU (245-697)

and OTU (339-697) constructs were expressed in Arctic Xpress cells

(Stratagene) Cells were induced at an OD600 of 06-08 with 150 microM IPTG

and grown overnight at 16 degC Cells from 6 L culture were lysed by sonication

in 50 ml lysis buffer (270 mM sucrose 50 mM Tris [pH 80] 1 mM EDTA 1

mM EGTA 10 mM sodium β-glycerophosphate 50 mM sodium fluoride 10

mM β-mercaptoethanol 1 mM benzamidine 01 mg mL-1 DNAse 1 1 mg mL-1

lysozyme) and cleared by centrifugation The cleared lysate was incubated

with 4 ml equilibrated glutathione-S-sepharose 4B resin (GE Healthcare) for 1

h and subsequently washed with 50 ml lysis buffer 500 ml buffer A (25 mM

Tris [pH 85] 1 mM EDTA 5 mM DTT) plus 500 mM NaCl and 500 ml buffer

A plus 150 mM NaCl The GST-tag was cleaved on the resin with 50 microg GST-

tagged PreScission protease overnight Cleaved protein was diluted to ~50

mM NaCl with 25 mM Tris (pH 85) and subjected to anion exchange

chromatography (MonoQ 550 GE Healthcare) where it eluted as a single

peak in a NaCl gradient from 50 to 500 mM

For crystallography peak fractions were pooled and subjected to gel filtration

(Superdex75) in buffer B (200 mM NaCl 25 mM Tris [pH 82] 1 mM EDTA 5

mM DTT) The protein was concentrated to 35 mg ml-1 using a VivaSpin 10

kDa MW cut-off concentrator and used in crystallization screening

TRABID Ank domain constructs were expressed in Rosetta2 pLysS cells and

were lysed and incubated with glutathione sepharose as described above

Crystallisation data collection phasing and refinement

The TRABID AnkOTU structure was determined from crystals grown at 23degC

from 150 mM NaCl 100 mM NaOAc 5 mM MgCl2 50 mM MES [pH 59] For

synchrotron data collection crystals were soaked in mother liquor containing

275 ethylene glycol and frozen in liquid nitrogen To obtain phase

information crystals were soaked in 1 mM KAu(CN)2 for 1 h prior to freezing

Diffraction data on the AnkOTU crystals were collected at the ESRF

(Grenoble) beamline ID23-2 Crystals displayed space group P212121 with

one molecule of AnkOTU in the asymmetric unit A native dataset collected to

225 Aring resolution and a peak wavelength SAD dataset at 3 Aring resolution from

AuCN soaked crystals were used for phasing using single isomorphous

replacement with anomalous scattering (SIRAS) An initial set of sites was

obtained with the SHELXhkl2map suite 5 and site refinement was performed

in SHARP 1 Density modification within SHARP resulted in a high-quality

map which was interpreted by WarpNTrace and manually rebuilt in Coot 6

Refinement was performed using PHENIX 7 including simulated annealing

and TLS B-factor refinement Final statistics can be found in Table 1

NMR titration analysis

For titration experiments HSQC spectra were recorded for 50 microM TRABID

alone and in presence of 250 microM and 1 mM unlabeled Ub For the reverse

experiment spectra were recorded for 50 microM of 15N-labelled Ub alone and in

complex with varying concentrations of unlabeled TRABID Ank domain either

wild-type or bearing point mutations (H317A I320D L332E) Separate

samples were prepared for each measurement such that no adjustment was

required to account for dilution with increasing volume For chemical shift

mapping weighted chemical shift perturbations were measured in 15N fast-

HSQC experiments 8 and defined as D1H + (D15N5) [ppm] 9 To obtain

approximate KD values by NMR peak frequencies (either 1H or 15N

whichever varied greatest in the titration) for nine representative correlations

were plotted as a function of the concentration of unlabeled protein at four

different concentrations and fitted to a quadratic expression for binding

equilibria as described

(httpstructbiovanderbilteduchazinwisdomkdcalchtm) KD values were

obtained by least squares fitting of the experimental data to trial curves

varying in the simulated KD Quoted KD values are the median of values

obtained for the nine peaks

Photobleaching experiments

FRAP (fluorescence recovery after photobleaching) experiments in COS-7

were carried out as described previously 10 Briefly cells were seeded onto

Lab-Tek II chambered cover-slides (Nalgene Nunc International Rochester

NY USA) 24 h before transfection Next 100 ng of GFP-TRABID constructs

were transfected using lipofectamine and photobleaching was conducted 18

h post transfection GFP puncta were bleached with five maximum-intensity

scans with the 488 and 514 nm lines of a 40 mW argon laser (Zeiss

AXIOVERT 200M inverted confocal microscope) Fluorescence recovery was

monitored in images taken during the following 60 seconds The fluorescence

intensity was normalized to the mean fluorescence intensity of the whole cell

For immunofluorescence full-length TRABID (2-708) TRABID AnkOTU (245-

708) TRABID OTU (339-708) were subcloned into pEGFP-C1 using

Xho1EcoR1 sites GFP-tagged TRABID constructs 2-200 2-345 FL-TRABID

ΔAnk (Δ249-338) TRABID Ank (245-345) as well as all other Ank mutants

used in this study were obtained by using the QuikChangereg technology

pEGFP-Cezanne wt 4 was used to derive pEGFP-Cezanne C194S

Protein purification for biochemical biophysical and structural studies

All protein purifications were performed at 4degC TRABID AnkOTU (245-697)

and OTU (339-697) constructs were expressed in Arctic Xpress cells

(Stratagene) Cells were induced at an OD600 of 06-08 with 150 microM IPTG

and grown overnight at 16 degC Cells from 6 L culture were lysed by sonication

in 50 ml lysis buffer (270 mM sucrose 50 mM Tris [pH 80] 1 mM EDTA 1

mM EGTA 10 mM sodium β-glycerophosphate 50 mM sodium fluoride 10

mM β-mercaptoethanol 1 mM benzamidine 01 mg mL-1 DNAse 1 1 mg mL-1

lysozyme) and cleared by centrifugation The cleared lysate was incubated

with 4 ml equilibrated glutathione-S-sepharose 4B resin (GE Healthcare) for 1

h and subsequently washed with 50 ml lysis buffer 500 ml buffer A (25 mM

Tris [pH 85] 1 mM EDTA 5 mM DTT) plus 500 mM NaCl and 500 ml buffer

mM NaCl with 25 mM Tris (pH 85) and subjected to anion exchange

chromatography (MonoQ 550 GE Healthcare) where it eluted as a single

peak in a NaCl gradient from 50 to 500 mM

For crystallography peak fractions were pooled and subjected to gel filtration

(Superdex75) in buffer B (200 mM NaCl 25 mM Tris [pH 82] 1 mM EDTA 5

mM DTT) The protein was concentrated to 35 mg ml-1 using a VivaSpin 10

kDa MW cut-off concentrator and used in crystallization screening

TRABID Ank domain constructs were expressed in Rosetta2 pLysS cells and

were lysed and incubated with glutathione sepharose as described above

Crystallisation data collection phasing and refinement

The TRABID AnkOTU structure was determined from crystals grown at 23degC

from 150 mM NaCl 100 mM NaOAc 5 mM MgCl2 50 mM MES [pH 59] For

synchrotron data collection crystals were soaked in mother liquor containing

275 ethylene glycol and frozen in liquid nitrogen To obtain phase

information crystals were soaked in 1 mM KAu(CN)2 for 1 h prior to freezing

Diffraction data on the AnkOTU crystals were collected at the ESRF

(Grenoble) beamline ID23-2 Crystals displayed space group P212121 with

one molecule of AnkOTU in the asymmetric unit A native dataset collected to

225 Aring resolution and a peak wavelength SAD dataset at 3 Aring resolution from

AuCN soaked crystals were used for phasing using single isomorphous

replacement with anomalous scattering (SIRAS) An initial set of sites was

obtained with the SHELXhkl2map suite 5 and site refinement was performed

in SHARP 1 Density modification within SHARP resulted in a high-quality

map which was interpreted by WarpNTrace and manually rebuilt in Coot 6

Refinement was performed using PHENIX 7 including simulated annealing

and TLS B-factor refinement Final statistics can be found in Table 1

NMR titration analysis

For titration experiments HSQC spectra were recorded for 50 microM TRABID

alone and in presence of 250 microM and 1 mM unlabeled Ub For the reverse

experiment spectra were recorded for 50 microM of 15N-labelled Ub alone and in

complex with varying concentrations of unlabeled TRABID Ank domain either

wild-type or bearing point mutations (H317A I320D L332E) Separate

samples were prepared for each measurement such that no adjustment was

required to account for dilution with increasing volume For chemical shift

mapping weighted chemical shift perturbations were measured in 15N fast-

HSQC experiments 8 and defined as D1H + (D15N5) [ppm] 9 To obtain

approximate KD values by NMR peak frequencies (either 1H or 15N

whichever varied greatest in the titration) for nine representative correlations

were plotted as a function of the concentration of unlabeled protein at four

different concentrations and fitted to a quadratic expression for binding

equilibria as described

(httpstructbiovanderbilteduchazinwisdomkdcalchtm) KD values were

obtained by least squares fitting of the experimental data to trial curves

varying in the simulated KD Quoted KD values are the median of values

obtained for the nine peaks

Photobleaching experiments

FRAP (fluorescence recovery after photobleaching) experiments in COS-7

were carried out as described previously 10 Briefly cells were seeded onto

Lab-Tek II chambered cover-slides (Nalgene Nunc International Rochester

NY USA) 24 h before transfection Next 100 ng of GFP-TRABID constructs

were transfected using lipofectamine and photobleaching was conducted 18

h post transfection GFP puncta were bleached with five maximum-intensity

scans with the 488 and 514 nm lines of a 40 mW argon laser (Zeiss

AXIOVERT 200M inverted confocal microscope) Fluorescence recovery was

monitored in images taken during the following 60 seconds The fluorescence

intensity was normalized to the mean fluorescence intensity of the whole cell

kDa MW cut-off concentrator and used in crystallization screening

TRABID Ank domain constructs were expressed in Rosetta2 pLysS cells and

were lysed and incubated with glutathione sepharose as described above

Crystallisation data collection phasing and refinement

The TRABID AnkOTU structure was determined from crystals grown at 23degC

from 150 mM NaCl 100 mM NaOAc 5 mM MgCl2 50 mM MES [pH 59] For

synchrotron data collection crystals were soaked in mother liquor containing

275 ethylene glycol and frozen in liquid nitrogen To obtain phase

information crystals were soaked in 1 mM KAu(CN)2 for 1 h prior to freezing

Diffraction data on the AnkOTU crystals were collected at the ESRF

(Grenoble) beamline ID23-2 Crystals displayed space group P212121 with

one molecule of AnkOTU in the asymmetric unit A native dataset collected to

225 Aring resolution and a peak wavelength SAD dataset at 3 Aring resolution from

AuCN soaked crystals were used for phasing using single isomorphous

replacement with anomalous scattering (SIRAS) An initial set of sites was

obtained with the SHELXhkl2map suite 5 and site refinement was performed

in SHARP 1 Density modification within SHARP resulted in a high-quality

map which was interpreted by WarpNTrace and manually rebuilt in Coot 6

Refinement was performed using PHENIX 7 including simulated annealing

and TLS B-factor refinement Final statistics can be found in Table 1

NMR titration analysis

For titration experiments HSQC spectra were recorded for 50 microM TRABID

alone and in presence of 250 microM and 1 mM unlabeled Ub For the reverse

experiment spectra were recorded for 50 microM of 15N-labelled Ub alone and in

complex with varying concentrations of unlabeled TRABID Ank domain either

wild-type or bearing point mutations (H317A I320D L332E) Separate

samples were prepared for each measurement such that no adjustment was

required to account for dilution with increasing volume For chemical shift

mapping weighted chemical shift perturbations were measured in 15N fast-

HSQC experiments 8 and defined as D1H + (D15N5) [ppm] 9 To obtain

approximate KD values by NMR peak frequencies (either 1H or 15N

whichever varied greatest in the titration) for nine representative correlations

were plotted as a function of the concentration of unlabeled protein at four

different concentrations and fitted to a quadratic expression for binding

equilibria as described

(httpstructbiovanderbilteduchazinwisdomkdcalchtm) KD values were

obtained by least squares fitting of the experimental data to trial curves

varying in the simulated KD Quoted KD values are the median of values

obtained for the nine peaks

Photobleaching experiments

FRAP (fluorescence recovery after photobleaching) experiments in COS-7

were carried out as described previously 10 Briefly cells were seeded onto

Lab-Tek II chambered cover-slides (Nalgene Nunc International Rochester

NY USA) 24 h before transfection Next 100 ng of GFP-TRABID constructs

were transfected using lipofectamine and photobleaching was conducted 18

h post transfection GFP puncta were bleached with five maximum-intensity

scans with the 488 and 514 nm lines of a 40 mW argon laser (Zeiss

AXIOVERT 200M inverted confocal microscope) Fluorescence recovery was

monitored in images taken during the following 60 seconds The fluorescence

intensity was normalized to the mean fluorescence intensity of the whole cell

NMR titration analysis

For titration experiments HSQC spectra were recorded for 50 microM TRABID

alone and in presence of 250 microM and 1 mM unlabeled Ub For the reverse

experiment spectra were recorded for 50 microM of 15N-labelled Ub alone and in

complex with varying concentrations of unlabeled TRABID Ank domain either

wild-type or bearing point mutations (H317A I320D L332E) Separate

samples were prepared for each measurement such that no adjustment was

required to account for dilution with increasing volume For chemical shift

mapping weighted chemical shift perturbations were measured in 15N fast-

HSQC experiments 8 and defined as D1H + (D15N5) [ppm] 9 To obtain

approximate KD values by NMR peak frequencies (either 1H or 15N

whichever varied greatest in the titration) for nine representative correlations

were plotted as a function of the concentration of unlabeled protein at four

different concentrations and fitted to a quadratic expression for binding

equilibria as described

(httpstructbiovanderbilteduchazinwisdomkdcalchtm) KD values were

obtained by least squares fitting of the experimental data to trial curves

varying in the simulated KD Quoted KD values are the median of values

obtained for the nine peaks

Photobleaching experiments

FRAP (fluorescence recovery after photobleaching) experiments in COS-7

were carried out as described previously 10 Briefly cells were seeded onto

Lab-Tek II chambered cover-slides (Nalgene Nunc International Rochester

NY USA) 24 h before transfection Next 100 ng of GFP-TRABID constructs

were transfected using lipofectamine and photobleaching was conducted 18

h post transfection GFP puncta were bleached with five maximum-intensity

scans with the 488 and 514 nm lines of a 40 mW argon laser (Zeiss

AXIOVERT 200M inverted confocal microscope) Fluorescence recovery was

monitored in images taken during the following 60 seconds The fluorescence

intensity was normalized to the mean fluorescence intensity of the whole cell

from 150 mM NaCl 100 mM NaOAc 5 mM MgCl2 50 mM MES [pH 59] For

synchrotron data collection crystals were soaked in mother liquor containing

275 ethylene glycol and frozen in liquid nitrogen To obtain phase

information crystals were soaked in 1 mM KAu(CN)2 for 1 h prior to freezing

Diffraction data on the AnkOTU crystals were collected at the ESRF

(Grenoble) beamline ID23-2 Crystals displayed space group P212121 with

one molecule of AnkOTU in the asymmetric unit A native dataset collected to

225 Aring resolution and a peak wavelength SAD dataset at 3 Aring resolution from

AuCN soaked crystals were used for phasing using single isomorphous

replacement with anomalous scattering (SIRAS) An initial set of sites was

obtained with the SHELXhkl2map suite 5 and site refinement was performed

in SHARP 1 Density modification within SHARP resulted in a high-quality

NMR titration analysis

For titration experiments HSQC spectra were recorded for 50 microM TRABID

alone and in presence of 250 microM and 1 mM unlabeled Ub For the reverse

experiment spectra were recorded for 50 microM of 15N-labelled Ub alone and in

complex with varying concentrations of unlabeled TRABID Ank domain either

wild-type or bearing point mutations (H317A I320D L332E) Separate

samples were prepared for each measurement such that no adjustment was

required to account for dilution with increasing volume For chemical shift

mapping weighted chemical shift perturbations were measured in 15N fast-

HSQC experiments 8 and defined as D1H + (D15N5) [ppm] 9 To obtain

approximate KD values by NMR peak frequencies (either 1H or 15N

whichever varied greatest in the titration) for nine representative correlations

were plotted as a function of the concentration of unlabeled protein at four

different concentrations and fitted to a quadratic expression for binding

equilibria as described

(httpstructbiovanderbilteduchazinwisdomkdcalchtm) KD values were

obtained by least squares fitting of the experimental data to trial curves

varying in the simulated KD Quoted KD values are the median of values

obtained for the nine peaks

Photobleaching experiments

FRAP (fluorescence recovery after photobleaching) experiments in COS-7

were carried out as described previously 10 Briefly cells were seeded onto

Lab-Tek II chambered cover-slides (Nalgene Nunc International Rochester

NY USA) 24 h before transfection Next 100 ng of GFP-TRABID constructs

were transfected using lipofectamine and photobleaching was conducted 18

h post transfection GFP puncta were bleached with five maximum-intensity

scans with the 488 and 514 nm lines of a 40 mW argon laser (Zeiss

AXIOVERT 200M inverted confocal microscope) Fluorescence recovery was

monitored in images taken during the following 60 seconds The fluorescence

intensity was normalized to the mean fluorescence intensity of the whole cell

Supplementary Methods

Cloning and mutagenesis

For bacterial expression TRABID AnkOTU (245-697) and Ank (245-339)

constructs were cloned into the pOPIN-K vector that comprises an N-terminal

PreScission-cleavable GST tag using the Infusion 20 Technology (Clontech)

Point mutants were generated by site directed mutagenesis using the

QuikChangereg technology (Stratagene) For mammalian expression full-

length TRABID (2-708) full-length TRABID NZF mutant 3 TRABID AnkOTU

(245-708) TRABID OTU (339-708) full-length TRABID ΔAnk (Δ249-338)

were subcloned into pCMV-3xFLAG (Stratagene) using EcoR1Xho1 sites

For immunofluorescence full-length TRABID (2-708) TRABID AnkOTU (245-

708) TRABID OTU (339-708) were subcloned into pEGFP-C1 using

Xho1EcoR1 sites GFP-tagged TRABID constructs 2-200 2-345 FL-TRABID

ΔAnk (Δ249-338) TRABID Ank (245-345) as well as all other Ank mutants

used in this study were obtained by using the QuikChangereg technology

pEGFP-Cezanne wt 4 was used to derive pEGFP-Cezanne C194S

Protein purification for biochemical biophysical and structural studies

All protein purifications were performed at 4degC TRABID AnkOTU (245-697)

and OTU (339-697) constructs were expressed in Arctic Xpress cells

(Stratagene) Cells were induced at an OD600 of 06-08 with 150 microM IPTG

and grown overnight at 16 degC Cells from 6 L culture were lysed by sonication

in 50 ml lysis buffer (270 mM sucrose 50 mM Tris [pH 80] 1 mM EDTA 1

mM EGTA 10 mM sodium β-glycerophosphate 50 mM sodium fluoride 10

mM β-mercaptoethanol 1 mM benzamidine 01 mg mL-1 DNAse 1 1 mg mL-1

lysozyme) and cleared by centrifugation The cleared lysate was incubated

with 4 ml equilibrated glutathione-S-sepharose 4B resin (GE Healthcare) for 1

h and subsequently washed with 50 ml lysis buffer 500 ml buffer A (25 mM

Tris [pH 85] 1 mM EDTA 5 mM DTT) plus 500 mM NaCl and 500 ml buffer

A plus 150 mM NaCl The GST-tag was cleaved on the resin with 50 microg GST-

tagged PreScission protease overnight Cleaved protein was diluted to ~50

mM NaCl with 25 mM Tris (pH 85) and subjected to anion exchange

chromatography (MonoQ 550 GE Healthcare) where it eluted as a single

peak in a NaCl gradient from 50 to 500 mM

For crystallography peak fractions were pooled and subjected to gel filtration

(Superdex75) in buffer B (200 mM NaCl 25 mM Tris [pH 82] 1 mM EDTA 5

mM DTT) The protein was concentrated to 35 mg ml-1 using a VivaSpin 10

kDa MW cut-off concentrator and used in crystallization screening

TRABID Ank domain constructs were expressed in Rosetta2 pLysS cells and

were lysed and incubated with glutathione sepharose as described above

Crystallisation data collection phasing and refinement

The TRABID AnkOTU structure was determined from crystals grown at 23degC

from 150 mM NaCl 100 mM NaOAc 5 mM MgCl2 50 mM MES [pH 59] For

synchrotron data collection crystals were soaked in mother liquor containing

275 ethylene glycol and frozen in liquid nitrogen To obtain phase

information crystals were soaked in 1 mM KAu(CN)2 for 1 h prior to freezing

Diffraction data on the AnkOTU crystals were collected at the ESRF

(Grenoble) beamline ID23-2 Crystals displayed space group P212121 with

one molecule of AnkOTU in the asymmetric unit A native dataset collected to

225 Aring resolution and a peak wavelength SAD dataset at 3 Aring resolution from

AuCN soaked crystals were used for phasing using single isomorphous

replacement with anomalous scattering (SIRAS) An initial set of sites was

obtained with the SHELXhkl2map suite 5 and site refinement was performed

in SHARP 1 Density modification within SHARP resulted in a high-quality

map which was interpreted by WarpNTrace and manually rebuilt in Coot 6

Refinement was performed using PHENIX 7 including simulated annealing

and TLS B-factor refinement Final statistics can be found in Table 1

NMR titration analysis

For titration experiments HSQC spectra were recorded for 50 microM TRABID

alone and in presence of 250 microM and 1 mM unlabeled Ub For the reverse

experiment spectra were recorded for 50 microM of 15N-labelled Ub alone and in

complex with varying concentrations of unlabeled TRABID Ank domain either

wild-type or bearing point mutations (H317A I320D L332E) Separate

samples were prepared for each measurement such that no adjustment was

required to account for dilution with increasing volume For chemical shift

mapping weighted chemical shift perturbations were measured in 15N fast-

HSQC experiments 8 and defined as D1H + (D15N5) [ppm] 9 To obtain

approximate KD values by NMR peak frequencies (either 1H or 15N

whichever varied greatest in the titration) for nine representative correlations

were plotted as a function of the concentration of unlabeled protein at four

different concentrations and fitted to a quadratic expression for binding

equilibria as described

(httpstructbiovanderbilteduchazinwisdomkdcalchtm) KD values were

obtained by least squares fitting of the experimental data to trial curves

varying in the simulated KD Quoted KD values are the median of values

obtained for the nine peaks

Photobleaching experiments

FRAP (fluorescence recovery after photobleaching) experiments in COS-7

were carried out as described previously 10 Briefly cells were seeded onto

Lab-Tek II chambered cover-slides (Nalgene Nunc International Rochester

NY USA) 24 h before transfection Next 100 ng of GFP-TRABID constructs

were transfected using lipofectamine and photobleaching was conducted 18

h post transfection GFP puncta were bleached with five maximum-intensity

scans with the 488 and 514 nm lines of a 40 mW argon laser (Zeiss

AXIOVERT 200M inverted confocal microscope) Fluorescence recovery was

monitored in images taken during the following 60 seconds The fluorescence

intensity was normalized to the mean fluorescence intensity of the whole cell
