Background
NRAS (NRAS proto-oncogene, GTPase) belongs to RAS small-GTPase family and functions as molecular switch governing proliferation and survival signaling. GTP-bound NRAS is active and triggers downstream RAF-MEK-ERK and PI3K cascades; GTP hydrolysis converts it into GDP-bound inactive conformation. Somatic point mutations (e.g. Q61) impair intrinsic GTPase activity and lock NRAS in constitutively active state, driving melanoma, leukemia and thyroid carcinoma. Wild-type NRAS responds to growth-factor cues and orchestrates normal cell-cycle progression. NRAS shares partial functional redundancy with KRAS and HRAS yet exhibits tissue-specific mutation profiles; NRAS-mutated tumors display distinct prognosis and therapeutic response compared with other RAS isoforms.
