ARPC4

Actin-related protein 2/3 complex subunit 4 is a protein that in humans is encoded by the ARPC4 gene.

Function
This gene encodes one of seven subunits of the human Arp2/3 protein complex. The Arp2/3 protein complex has been implicated in the control of actin polymerization in cells and has been conserved through evolution. The exact role of the protein encoded by this gene, the p20 subunit, has yet to be determined. Three transcript variants encoding two distinct isoforms have been found for this gene.

Interactions
ARPC4 has been shown to interact with ARPC5.
