NOTCH1 (Neurogenic locus notch homolog protein 1) is a protein that switches other genes on and off. The public catalogues list it as a drug target, an oncogene driver, a tumour suppressor and a biomarker, and clinical evidence ties its variants to diagnosis, prognosis or drug response. Tied to Leukaemia, Non-Hodgkin lymphoma, Head and neck squamous cell carcinoma and 5 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.
Functions as a receptor for membrane-bound ligands Jagged-1 (JAG1), Jagged-2 (JAG2) and Delta-1 (DLL1) to regulate cell-fate determination. Upon ligand activation through the released notch intracellular domain (NICD) it forms a transcriptional activator complex with RBPJ/RBPSUH and activates genes of the enhancer of split locus. Affects the implementation of differentiation, proliferation and apoptotic programs. Involved in angiogenesis; negatively regulates endothelial cell proliferation and migration and angiogenic sprouting. Involved in the maturation of both CD4(+) and CD8(+) cells in the thymus. Important for follicular differentiation and possibly cell fate selection within the follicle. Location: Cell membrane; Late endosome membrane; Nucleus (UniProt). Locus 9q34.3 (HGNC).
| Cancer | Prevalence | Measure | Note | Source |
|---|---|---|---|---|
| Small-cell lung cancer | 13-25% | Inactivating mutation | cBioPortal: NOTCH1 mutated in 16 of 120, 13.3%, in sclc_ucologne_2015. Inactivating mutations across the NOTCH family were found in 25% of the sequenced tumours, and activating Notch signalling in a mouse model strikingly reduced tumour number, extended survival and abolished neuroendocrine gene expression (George 2015). | cBioPortal (TCGA) |
| Triple-negative breast cancer | 5-9% | Activating rearrangement, PEST-domain mutation or amplification | NOTCH1 and NOTCH2 rearrangements causing constitutive activation in 6 of 66 TNBCs, 9%, and in no other solid tumour type (Stoeck 2014); PEST-domain mutations of NOTCH1, NOTCH2 and NOTCH3 and focal NOTCH2/NOTCH3 amplifications significantly enriched in the TNBC subset of TCGA (Wang 2015); cBioPortal: NOTCH1 mutation in 16 of 299, 5.4%, in brca_metabric and 9 of 176, 5.1%, in breast_msk_2018; NOTCH2 amplification in 21 of 119, 17.6%, in brca_tcga_pan_can_atlas_2018. | doi.org |
