Ras proteins bind GDP/GTP and possess intrinsic GTPase activity. GTP + H2O = GDP + H(+) + phosphate Alternates 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). Interacts (active GTP-bound form preferentially) with RGS14 (By similarity). Interacts (active GTP-bound form) with RASSF7 (PubMed:21278800). Shuttles between the plasma membrane and the Golgi apparatus. Palmitoylated by the ZDHHC9-GOLGA7 complex (PubMed:16000296). Depalmitoylated by ABHD17A, ABHD17B and ABHD17C (PubMed:26701913). A continuous cycle of de- and re-palmitoylation regulates rapid exchange between plasma membrane and Golgi (PubMed:16000296, PubMed:15705808, PubMed:2661017, PubMed:26701913). Acetylation at Lys-104 prevents interaction with guanine nucleotide exchange factors (GEFs). Fatty-acylated at Lys-169 and/or Lys-170. Ubiquitinated by the BCR(LZTR1) E3 ubiquitin ligase complex at Lys-170 in a non-degradative manner, leading to inhibit Ras signaling by decreasing Ras association with membranes. Phosphorylation at Ser-89 by STK19 enhances NRAS-association with its downstream effectors. (Microbial infection) Glucosylated at Thr-35 by P.sordellii toxin TcsL.

Mutations which change AA 12, 13 or 61 activate the potential of Ras to transform cultured cells and are implicated in a variety of human tumors. Belongs to the small GTPase superfamily. Ras family.
