TRANSCRIPT
Engineer “Arg-Gly-Asp” (RGD) epitopes for multi-valent display
RGD: stem-cell
adhesion epitopealso target cancer
cells that up-regulate integrin
TYMV with RGD substitution at residue 44
Wild-type 70°C
N-term mutant 70°C
pH-dependent enhanced stabilityMutate internal scaffold N-terminus of TYMV CP
Robust TYMV virus-like particles in E. coli
In vitro reassembly from a denatured
state
After many monthscrystal structure
data for TYMV and mutants!
TYMV can form a molecular “container” after release of RNA, nano-inspired applications with a protein shell with a small “hole”
After freeze-thaw
before
TYMV dual-subgenomic RNA for expression of GFP and GUS. Future downstream use for vaccine development
Biophysical studies of TYMVCharacterization empty, virion and intermediate particles
Northerns, Westerns, gradient centrifugation, etc.
Previous Work (M.S degree at OHSU): Signaling of a Cytomegalovirus chemokine receptor US28: plenty of cloning, tissue culture, immuno-precipitation/fluorescence and construction of CMV knockout mutants
