PFAM accession number:PF05824
Interpro abstract (IPR005456):

Melanin-concentrating hormone (MCH) is a cyclic peptide originally identified in teleost fish [(PUBMED:10421367),(PUBMED:10421368)]. In fish, MCH is released from the pituitary and causes lightening of skin pigment cells through pigment aggregation [(PUBMED:10996523)]. In mammals, MCH is predominantly expressed in the hypothalamus, and functions as a neurotransmitter in the control of a range of functions. A major role of MCH is thought to be in the regulation of feeding: injection of MCH into rat brains stimulates feeding; expression of MCH is upregulated in the hypothalamus of obese and fasting mice; and mice lacking MCH are lean and eat less [(PUBMED:10421367)]. MCH and alpha melanocyte-stimulating hormone (alpha-MSH) have antagonistic effects on a number of physiological functions. Alpha-MSH darkens pigmentation in fish and reduces feeding in mammals, whereas MCH increases feeding [(PUBMED:10996523)].

MCH is derived from a pre-pro-hormone (pre-pro-MCH), which contains 1-2 hormones other than MCH, depending on the species. In all species, the 17-19 C-terminal amino acids are cleaved to release MCH. In mammals, amino acids 132-144 encode the hormone neuropeptide EI (NEI), whilst in salmonids, the analogous region encodes neuropeptide EV (NEV), and in other fish, the region determines MCH gene-related peptide (Mgrp) [(PUBMED:8559281)]. A further peptide, known as neuropeptide GE (NGE), is thought to be found in mammalian pre-pro-MCH upstream of NEI, encoded by amino acids 110-129. NEI has been shown to enhance oxytocin and reduce arginine vasopressin secretion from rat pituitary [(PUBMED:9175893)]. Two paralogues of MCH, known as pro-MCH-like 1 and 2 genes (PMCHL1 and PMCHL2), which arose recently in primate evolution, also exist. At present, it is unclear whether the PMCHL genes are functional genes or inactive pseudogenes.
