NRAS NRAS proto-oncogene, GTPase
ENSG00000213281 · protein coding · Open Targets profile
Signal transducer in the Ras-MAPK signaling pathway that regulates cell proliferation and survival (PubMed:30712867). Ras proteins bind GDP/GTP and possess intrinsic GTPase activity (PubMed:30712867). Recognized by LZTR1 that mediates its ubiquitination by a BCR (BTB-CUL3-RBX1) E3 ubiquitin-protein ligase complex (PubMed:40934300). {ECO:0000269|PubMed:30712867, ECO:0000269|PubMed:40934300}.
Each row is a cancer, strongest overall evidence first. The two dots show how strong the inherited (germline) and tumour-mutation (somatic) evidence is; the line between them is the gap.
Scores run from 0 (no evidence) to 1 (strongest). A missing dot at 0 means Open Targets holds no evidence of that kind. Source: Open Targets Platform, fetched live.

gnomAD loss of function constraint: o/e 0.28161001205444336 (upper bound 0.5558300018310547). Low values mean loss of function is poorly tolerated, a safety flag for inhibition.
