Actin-related protein 3 is a protein that in humans is encoded by the ACTR3 gene.^[1]

Function

The specific function of this gene has not yet been determined; however, the protein it encodes is known to be a major constituent of the ARP2/3 complex. This complex is located at the cell surface and is essential to cell shape and motility through lamellipodial actin assembly and protrusion.^[2]

Interactions

ACTR3 has been shown to interact with Cortactin.^[3]^[4]
