Rho GTPase activating protein 21 is a protein that in humans is encoded by the ARHGAP21 gene.^[5]

Function

ARHGAP21 functions preferentially as a GTPase-activating protein (GAP) for CDC42 (MIM 116952) and regulates the ARP2/3 complex (MIM 604221) and F-actin dynamics at the Golgi through control of CDC42 activity.^[6] There is little scientific literature on ARHGAP21, but recent reviews highlighted that it plays an important role in cytoskeletal processes in cancer, substance transport within the cell, and insulin secretion ^[7]
