Predicted to enable GDP binding activity; GTP binding activity; and GTPase activity. Predicted to be involved in several processes, including Ras protein signal transduction; negative regulation of cell growth; and negative regulation of cell population proliferation. Predicted to be located in cytosol; fibrillar center; and nucleoplasm. Predicted to be active in plasma membrane. Is expressed in bladder; gonad; limb; and sensory organ. Orthologous to human RERG (RAS like estrogen regulated growth inhibitor). [provided by Alliance of Genome Resources, Apr 2022]
