Ras proteins bind GDP/GTP and possess intrinsic GTPase activity. Interacts with PHLPP. Interacts (active GTP-bound form preferentially) with RGS14. Alternate between an inactive form bound to GDP and an active form bound to GTP. Activated by a guanine nucleotide-exchange factor (GEF) and inactivated by a GTPase- activating protein (GAP). Belongs to the small GTPase superfamily. Ras family. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
