DESCRIPTION

Also known as APC5B_XENLA, arpc5-b, arpc5l. Component of the Arp2/3 complex, a multiprotein complex that mediates actin polymerization upon stimulation by nucleation-promoting factor (NPF) (By similarity). The Arp2/3 complex mediates the formation of branched actin networks in the cytoplasm, providing the force for cell motility (By similarity). In addition to its role in the cytoplasmic cytoskeleton, the Arp2/3 complex also promotes actin polymerization in the nucleus, thereby regulating gene transcription and repair of damaged DNA (Probable). The Arp2/3 complex promotes homologous recombination (HR) repair in response to DNA damage by promoting nuclear actin polymerization, leading to drive motility of double-strand breaks (DSBs) (By similarity). Component of the Arp2/3 complex composed of actr2/arp2, actr3/arp3, arpc1 (arpc1a or arpc1b), arpc2, arpc3, arpc4 and arpc5.
