SH3BP1: Proteins and Enzymes

Binds differentially to the SH3 domains of certain proteins of signal transduction pathways. This protein binds preferentially to c-Abl proto-oncogene, SRC and GRB2. Shows GAP activity for Rac-related proteins but not for Rho- or Ras-related proteins. It inhibits PDGF-induced membrane ruffling mediated by Rac (By similarity).
