Rho GTPase activating protein 26 (ARHGAP26; also known as GRAF) is a gene that encodes a protein that functions in binding to focal adhesion kinases. The protein also regulates the activity of GTP binding proteins RhoA and Cdc42. Fusions, missense, nonsense, and silent mutations are observed in cancers such as endometrial cancer, intestinal cancer, and stomach cancer.
