Enables molecular adaptor activity. Involved in actin cortical patch organization. Part of Arp2/3 protein complex. Used to study cancer. Orthologous to human ARPC4 (actin related protein 2/3 complex subunit 4).
SGD Description
Subunit of the ARP2/3 complex; ARP2/3 is required for the motility and integrity of cortical actin patches; mutation is functionally complemented by human ARPC4
