Summaries for MCHR1 Gene

Entrez Gene Summary for MCHR1 Gene

  • The protein encoded by this gene, a member of the G protein-coupled receptor family 1, is an integral plasma membrane protein which binds melanin-concentrating hormone. The encoded protein can inhibit cAMP accumulation and stimulate intracellular calcium flux, and is probably involved in the neuronal regulation of food consumption. Although structurally similar to somatostatin receptors, this protein does not seem to bind somatostatin. [provided by RefSeq, Jul 2008]

GeneCards Summary for MCHR1 Gene

MCHR1 (Melanin-Concentrating Hormone Receptor 1) is a Protein Coding gene. Among its related pathways are Signaling by GPCR and Signaling by GPCR. GO annotations related to this gene include G-protein coupled receptor activity and hormone binding. An important paralog of this gene is GALR2.

UniProtKB/Swiss-Prot for MCHR1 Gene

  • Receptor for melanin-concentrating hormone, coupled to both G proteins that inhibit adenylyl cyclase and G proteins that activate phosphoinositide hydrolysis.

Tocris Summary for MCHR1 Gene

  • Melanin-concentrating hormone (MCH) is a neuropeptide that is expressed in the central and peripheral nervous systems and plays an important role in the control of feeding behaviors and energy metabolism. MCH acts on two GPCRs; MCH1 (GPR24) and MCH2 (GPR145). MCH1 and MCH2 have very similar tissue distribution patterns and are expressed in many brain regions, particularly the ventromedial, dorsalmedial and arcuate nuclei of the hypothalamus and zona incerta. They are also found at lower levels in the periphery including in the pituitary gland, adipose tissue and pancreas. MCH1 is a target for the orexigenic peptide leptin, which supports a role for MCH receptors in the control of food intake and energy expenditure. The human genes encoding MCH1 and MCH2 are localized to chromosomes 22q13.3 and 6q21 respectively. MCH2 is a pseudogene in rodents.
