SOS1 (Son of sevenless homolog 1) is a gene that drives cell growth when it is altered. The public catalogues list it as an oncogene driver and a biomarker, and clinical evidence ties its variants to diagnosis, prognosis or drug response. Tied to Endometrial cancer, Skin cancer, Breast cancer and 1 more. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.
Biology
Promotes the exchange of Ras-bound GDP by GTP. Probably by promoting Ras activation, regulates phosphorylation of MAP kinase MAPK3/ERK1 in response to EGF. Catalytic component of a trimeric complex that participates in transduction of signals from Ras to Rac by promoting the Rac-specific guanine nucleotide exchange factor (GEF) activity. Locus 2p22.1 (HGNC).
