May play a role in regulating A disintegrin and metalloproteases (ADAMs) in the signaling of EGFR-ligand shedding. May be involved in suppression of Ras-induced cellular transformation and Ras-mediated activation of ELK1. Plays a role in the regulation of cell morphology and cytoskeletal organization. Interacts with ADAM12. Isoform 4 and isoform 5 (but not isoform 1 and isoform 2) interact with ADAM9, ADAM10, ADAM15 and ADAM17. Interacts with SH3GL1 SH3 domain. Interacts via SH3 3 and SH3 4 or SH3 4 and SH3 5 domains with SOS2. Probably forms a trimeric complex with SH3GL1 and SOS2. Interacts with SH3YL1 (By similarity). Is recruited to the nucleus by the KMT2A/MLL1-EEN fusion protein. Widely expressed with highest levels in heart, skeletal muscle, kidney, liver, placenta, small intestine and lung. Expressed at low levels in colon, thymus, spleen and leukocytes. It is uncertain whether Met-1 or Met-4 is the initiator.
