Protein
Actin-related protein 2/3 complex subunit 4
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
Functions as actin-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 mother actin filament (By similarity).
Similarity
Belongs to the ARPC4 family.
