Summary: MC2R encodes one member of the five-member G-protein associated melanocortin receptor family. Melanocortins (melanocyte-stimulating hormones and adrenocorticotropic hormone) are peptides derived from pro-opiomelanocortin (POMC). MC2R is selectively activated by adrenocorticotropic hormone, whereas the other four melanocortin receptors recognize a variety of melanocortin ligands. Mutations in MC2R can result in familial glucocorticoid deficiency. Alternate transcript variants have been found for this gene. [provided by RefSeq, May 2014]

Results indicate that substitution of the amino acid residue leucine to isoleucine in 112 (L112I) of one of the transmembrane domains in the MC2R changes from both DPhe-ACTH1-17 and ACTH1-15 from no activity to agonists. Also, mutation L112I switches alpha-MSH from no activity to agonist, suggesting that this residue plays a key role at MC2R for ligand ACTH or alpha-MSH selectivity.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
