MC1R (Melanocyte-stimulating hormone receptor) is a gene. In the public catalogues the evidence so far is association rather than a proven role. Tied to Skin cancer, Melanoma and Basal cell carcinoma. 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
G protein-coupled receptor that binds melanocyte-stimulating hormones (alpha, beta, and gamma-MSH) and adrenocorticotropic hormone/ACTH, which are peptide products of the POMC precursor protein. Upon activation, MC1R couples with the G(s) protein, stimulating adenylate cyclase and activating the cAMP-dependent signalling pathway. This activation promotes melanogenesis, resulting in the production of eumelanin (black/brown) and pheomelanin (red/yellow) in melanocytes. MC1R interacts with G protein-coupled receptor opsin 3/OPN3, which couples to G(i) proteins and inhibits the alpha-MSH-induced cAMP response, thereby reducing melanin synthesis. Binding to Agouti/ASP precludes alpha-MSH-induced signalling, thereby down-regulating melanogenesis. Additionally, interaction with MGRN1 displaces the G(s) protein, further suppressing MC1R signalling. Location: Cell membrane (UniProt). Locus 16q24.3 (HGNC).
