The different subtypes of the melanocortin (MC) receptors, which are a subfamily of G-protein-coupled receptors (GPCRs), play a variety of physiological roles, including pigmentation, steroid secretion, energy homeostasis, and food intake. Five G-protein-coupled receptors (MC1R-MC5R) make up the melanocortin receptor (MCR) family. The MC1R regulates pigmentation, the MC2R is an essential part of the hypothalamic-pituitary-adrenal axis, the MC3R, MC4R, and MC5R are involved in exocrine function, and they all play a significant role in energy homeostasis.
A number of neuropeptides known as melanocortins, such as adrenocorticotropic hormone (ACTH) and,, and -melanocyte-stimulating hormones (MSHs), activate MCRs. Pro-opiomelanocortin, a common polypeptide precursor that is primarily expressed in the hypothalamus and pituitary, is processed post-translationally to produce melanocortins.
