1) One of our research interests centers around studying at atomic resolution the structural and functional properties that define molecular recognition systems that activate and regulate biological properties. In particular, we study the energetics of hormone-induced receptor activation and regulation of growth hormone and its receptor using X-ray crystallography, site-directed mutagenesis, phage display mutagenesis and biophysical analysis. 2) Synthetic Antibodies- We use novel phage display libraries and screening procedures to produce a new class of synthetic affinity binders (sABs) based on Fab antibody scaffolds. These synthetic antibodies are much more versatile than traditional monoclonal antibodies and can be tuned to bind to multi-protein complexes and specific conformational states of their protein targets. These attributes make them the reagents of choice to study complex processes like cell signaling and cytokinesis. 3) Drug delivery- We have developed a unique drug delivery method that utilizes ligand-induced receptor-mediated endocytosis pathways. We call this method Receptor-Mediated Delivery (RMD) and have shown that we can deliver functionally active proteins and RNA/DNA cargoes into live cells for functional and imaging experiments. 4) Synthetic biology- We use a combination of peptide synthesis and phage display (biosynthetic phage display) to produce proteins with novel properties.
