Abl interactor 1 has been found to form a complex with EPS8 and SOS1, and is thought to be involved in the transduction of signals from Ras to Rac. In addition, the encoded protein may play a role in the regulation of EGF-induced Erk pathway activation as well as cytoskeletal reorganization and EGFR signaling. Several transcript variants encoding multiple isoforms have been found for this gene.[3]
Abi1 is adaptor protein. It interacts with c-Abl and WAVE2 which is an actin polymerization regulator. It is known that Abi1 enhances the phosphorylation of WAVE2 by c-Abl. The phosphorylation of c-Abl promotes actin polymerization. Furthermore, Abi1 is a component of the WAVE complex. Some research has shown that knockdown of Abi1 by siRNA promoted degradation of WAVE complex proteins.[citation needed]
