Detailed entry information

Protein Information (annotations from UniProt)

Database IDHIV0000037
UniProt IDP61158
Primary gene name(s)ACTR3
Synonym gene name(s)ARP3
Protein nameActin-related protein 3
Protein functionFunctions 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. {ECO:0000269|PubMed:20393563, ECO:0000269|PubMed:9000076}.
Subcellular locationCytoplasm, cytoskeleton {ECO:0000269|PubMed:19109554}. Cell projection {ECO:0000269|PubMed:9230079}. Note=In pre-apoptotic cells, colocalizes with MEFV in large specks, pyroptosomes, PubMed:19109554.
