CC -!- FUNCTION: Functions as a component of the Arp2/3 complex which is
CC involved in regulation of actin polymerization and together with an
CC activating nucleation-promoting factor (NPF) mediates the formation of
CC branched actin networks. {ECO:0000250}.
CC -!- SUBUNIT: Component of the Arp2/3 complex composed of arp2, act2,
CC arc1/p41-ARC, arc2/p34-ARC, arc3/p21-ARC, arc4/p20-ARC and arc5/p16-
CC ARC. {ECO:0000269|PubMed:10588653}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton, actin patch.
CC -!- SIMILARITY: Belongs to the WD repeat ARPC1 family. {ECO:0000305}.
