CC -!- FUNCTION: Actin-binding component of the Arp2/3 complex, a multiprotein CC complex that mediates actin polymerization upon stimulation by CC nucleation-promoting factor (NPF). The Arp2/3 complex mediates the CC formation of branched actin networks in the cytoplasm, providing the CC force for cell motility. Seems to contact the mother actin filament. In CC 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. The Arp2/3 CC complex promotes homologous recombination (HR) repair in response to CC DNA damage by promoting nuclear actin polymerization, leading to drive CC motility of double-strand breaks (DSBs). CC {ECO:0000250|UniProtKB:O15144}. CC -!- SUBUNIT: Component of the Arp2/3 complex composed of ACTR2/ARP2, CC ACTR3/ARP3, ARPC1B/p41-ARC, ARPC2/p34-ARC, ARPC3/p21-ARC, ARPC4/p20-ARC CC and ARPC5/p16-ARC (By similarity). Interacts with SHANK3; the CC interaction probably mediates the association of SHANK3 with the Arp2/3 CC complex (PubMed:24153177). Interacts with DNAI3; this interaction CC reduces binding of the Arp2/3 complex to the VCA domain of nucleation CC promoting factors (By similarity). {ECO:0000250|UniProtKB:O15144, CC ECO:0000250|UniProtKB:P61160, ECO:0000269|PubMed:24153177}. CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton CC {ECO:0000250|UniProtKB:O15144}. Cell projection CC {ECO:0000250|UniProtKB:O15144}. Synapse, synaptosome CC {ECO:0000269|PubMed:24153177}. Nucleus {ECO:0000250|UniProtKB:O15144}. CC -!- TISSUE SPECIFICITY: Expressed in hippocampal neurons (at protein CC level). {ECO:0000269|PubMed:24153177}. CC -!- SIMILARITY: Belongs to the ARPC2 family. {ECO:0000305}.
