Biol. 5:17-17(2011). CC -!- FUNCTION: Functions as ATP-binding component of the Arp2/3 complex CC which is involved in regulation of actin polymerization and CC together with an activating nucleation-promoting factor (NPF) CC mediates the formation of branched actin networks. Seems to CC contact the pointed end of the daughter actin filament. Plays a CC role in ciliogenesis. CC -!- SUBUNIT: Component of the Arp2/3 complex composed of ARP2, ARP3, CC ARPC1B/p41-ARC, ARPC2/p34-ARC, ARPC3/p21-ARC, ARPC4/p20-ARC and CC ARPC5/p16-ARC. Interacts with WHDC1. CC -!- INTERACTION: CC O60739:EIF1B; NbExp=1; IntAct=EBI-351428, EBI-1043343; CC P17535:JUND; NbExp=1; IntAct=EBI-351428, EBI-2682803; CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton. Cell projection. CC -!- SIMILARITY: Belongs to the actin family. ARP3 subfamily.
