This gene encodes a multiple SH3 domain-containing protein, which interacts with other proteins, such as EBP and members of ADAM family, via the SH3 domains. This protein may be involved in suppression of Ras-induced cellular transformation and Ras-mediated activation of ELK1 by EBP, and regulation of ADAM proteins in the signaling of EGFR-ligand shedding. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. Protein Interaction Partner: SH3YL1, SH3KBP1, ELAVL1, Cd2ap, GRB2, CDC42, ADAM15, ADAM17, SH3GL3, ADAM12, ADAM9, ADAM10, SH3GL1, SOS2, Protein Size: 420
