CC -!- FUNCTION: ATP-binding component of the Arp2/3 complex, a multiprotein CC complex that mediates actin polymerization upon stimulation by CC nucleation-promoting factor (NPF) (PubMed:9000076). The Arp2/3 complex CC mediates the formation of branched actin networks in the cytoplasm, CC providing the force for cell motility (PubMed:9000076). Seems to CC contact the pointed end of the daughter actin filament CC (PubMed:9000076). In podocytes, required for the formation of CC lamellipodia downstream of AVIL and PLCE1 regulation (PubMed:29058690). CC In addition to its role in the cytoplasmic cytoskeleton, the Arp2/3 CC complex also promotes actin polymerization in the nucleus, thereby CC regulating gene transcription and repair of damaged DNA CC (PubMed:17220302, PubMed:29925947). The Arp2/3 complex promotes CC homologous recombination (HR) repair in response to DNA damage by CC promoting nuclear actin polymerization, leading to drive motility of CC double-strand breaks (DSBs) (PubMed:29925947). Plays a role in CC ciliogenesis (PubMed:20393563). {ECO:0000269|PubMed:17220302, CC ECO:0000269|PubMed:20393563, ECO:0000269|PubMed:29058690, CC ECO:0000269|PubMed:29925947, ECO:0000269|PubMed:9000076}.
