CC   -!- FUNCTION: Functions as actin-binding component of the Arp2/3 complex
CC       which is involved in regulation of actin polymerization and together
CC       with an activating nucleation-promoting factor (NPF) mediates the
CC       formation of branched actin networks. Seems to contact the mother actin
CC       filament (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Component of the Arp2/3 complex composed of ARP2, ARP3,
CC       ARC40/p41-ARC, ARC35/p34-ARC, ARC18/p21-ARC, ARC19/p20-ARC and
CC       ARC16/p16-ARC. {ECO:0000269|PubMed:9210376}.
CC   -!- INTERACTION:
CC       P33204; Q05933: ARC18; NbExp=4; IntAct=EBI-2757, EBI-2764;
CC       P33204; P53731: ARC35; NbExp=4; IntAct=EBI-2757, EBI-2770;
CC       P33204; P38328: ARC40; NbExp=5; IntAct=EBI-2757, EBI-2777;
CC       P33204; Q04439: MYO5; NbExp=3; IntAct=EBI-2757, EBI-11687;
CC   -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton, actin patch.
CC   -!- MISCELLANEOUS: Present with 9020 molecules/cell in log phase SD medium.
CC       {ECO:0000269|PubMed:14562106}.
CC   -!- SIMILARITY: Belongs to the ARPC4 family. {ECO:0000305}.
