General annotation (Comments)

Function	Functions as ATP-binding component of the Arp2/3 complex which is involved in regulation of actin polymerization and together with an activating nucleation-promoting factor (NPF) mediates the formation of branched actin networks. Seems to contact the pointed end of the daughter actin filament By similarity.
Subunit structure	Component of the Arp2/3 complex composed of ARP2, ARP3, ARC40/p41-ARC, ARC35/p34-ARC, ARC18/p21-ARC, ARC19/p20-ARC and ARC16/p16-ARC.
Subcellular location	Cytoplasm › cytoskeleton › actin patch. Ref.3 Ref.5
Miscellaneous	Present with 6650 molecules/cell in log phase SD medium. Ref.6
Sequence similarities	Belongs to the actin family. ARP2 subfamily.
