Protein Structure

UniProt Annotation

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. Plays a role in ciliogenesis (By similarity). {ECO:0000250}.

Subcellular Localization

Cytoplasm, cytoskeleton {ECO:0000250}. Cell projection {ECO:0000250}. Note=In pre-apoptotic cells, colocalizes with MEFV in large specks (pyroptosomes). {ECO:0000250}.
