Phage display identifies novel toxic binding peptides for the disordered oncoprotein EWS-FLI1 (Abstract #3412)

EMBARGO: Tuesday, April 20, 2010, 9 AM

Author's summary: "The EWS-FLI1 protein results from a tumor-specific chromosomal translocation and is uniquely expressed in Ewing's Sarcoma Family Tumors (ESFT). EWS-FLI1 is a disordered protein and thus presents opportunities for manipulating protein-protein interactions, some of which will be specific anti-tumor targets. By looking at and identifying various peptides and their cognate proteins, we can investigate the function of EWS-FLI1 in order to improve therapies for ESFT patients. The A1 peptide, which we focused on specifically, appears to directly bind to the EWS-FLI1 protein and lead to cell death in cells with the EWS-FLI1 fusion protein." - Lauren M. Jacobwitz
