Previous GeneCards Identifiers for MC3R Gene
This gene encodes a G-protein-coupled receptor for melanocyte-stimulating hormone and adrenocorticotropic hormone that is expressed in tissues other than the adrenal cortex and melanocytes. This gene maps to the same region as the locus for benign neonatal epilepsy. Mice deficient for this gene have increased fat mass despite decreased food intake, suggesting a role for this gene product in the regulation of energy homeostasis. Mutations in this gene are associated with a susceptibility to obesity in humans. [provided by RefSeq, Jul 2008]
GeneCards Summary for MC3R Gene
MC3R (Melanocortin 3 Receptor) is a Protein Coding gene. Diseases associated with MC3R include obesity, severe bmiq9 and obesity, susceptibility to, mc3r-related. Among its related pathways are Signaling by GPCR and Signaling by GPCR. GO annotations related to this gene include peptide hormone binding and melanocortin receptor activity. An important paralog of this gene is LPAR1.
UniProtKB/Swiss-Prot for MC3R Gene
Receptor for MSH (alpha, beta and gamma) and ACTH. This receptor is mediated by G proteins which activate adenylate cyclase. Required for expression of anticipatory patterns of activity and wakefulness during periods of limited nutrient availability and for the normal regulation of circadian clock activity in the brain.
Melanocortin receptors are activated by members of the melanocortin family: alpha-, beta- and gamma-melanocyte stimulating hormone (MSH) and adrenocorticotropic hormone (ACTH). Endogenous antagonists include agouti and agouti-related protein (AgRP). The melanocortin receptors are G-protein-coupled and 5 subtypes exist, MC1-5. The melanocortins are involved in a wide range of physiological functions, including pigmentation, energy homeostasis, inflammation, immunomodulation, steroidogenesis and temperature control.
