DESCRIPTION

Also known as ABP1_YEAST, ABP1. Regulates ARP2/3 complex-mediated actin assembly. Recruits ARP2/3 complex to sides of preexisting actin filaments, which may promote nucleation or stabilization of filament branches. Binds to actin filaments, but not actin monomers. Actin binding is required for ARP2/3 complex activation. May also have a role in linking the actin cytoskeleton to endocytosis. recruits components of the endocytotic machinery to cortical actin patches, known sites of endocytosis. Binds F-actin, but not G-actin. Interacts with the ARP2/3 complex. Interacts with APP1, ARK1, PRK1, SCP1, SRV2 and YIR003W via its SH3 domain. Interacts with the SH3 domain of RVS167 and with SLA1.
