ACTIVITY REGULATION: 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).

proteins
function
FUNCTION: Signal transducer in the Ras-MAPK signaling pathway that regulates cell proliferation and survival (By similarity). Ras proteins bind GDP/GTP and possess intrinsic GTPase activity (By similarity). Recognized by LZTR1 that mediates its ubiquitination by a BCR (BTB-CUL3-RBX1) E3 ubiquitin-protein ligase complex (By similarity). {ECO:0000250|UniProtKB:P01111}.

post_translational_modification
PTM: Palmitoylated by the ZDHHC9-GOLGA7 complex. Depalmitoylated by ABHD17A, ABHD17B and ABHD17C. A continuous cycle of de- and re-palmitoylation regulates rapid exchange between plasma membrane and Golgi. {ECO:0000250|UniProtKB:P01111}.; PTM: Acetylation at Lys-104 prevents interaction with guanine nucleotide exchange factors (GEFs). {ECO:0000250|UniProtKB:P01116}.; PTM: 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. {ECO:0000250|UniProtKB:P01112}.; PTM: Phosphorylation at Ser-89 enhances NRAS association with its downstream effectors. {ECO:0000250|UniProtKB:P01111}.
