Human Gene MC3R (ENST00000243911.2) from GENCODE V44
  Description: Homo sapiens melanocortin 3 receptor (MC3R), mRNA. (from RefSeq NM_019888)
RefSeq Summary (NM_019888): 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]. Sequence Note: A downstream start codon is selected for this RefSeq based on conservation with homologs and for consistency with other family members, including the human melanocortin 4 and melanocortin 5 receptors. The use of an alternative upstream start codon, which is specific to primate species, would increase the protein length from 323 aa to 360 aa. This longer protein is referred to in the literature, including PMIDs 15292330 and 8463333.

  ID: MC3R_HUMAN
DESCRIPTION: RecName: Full=Melanocortin receptor 3; Short=MC3-R;
FUNCTION: Receptor for MSH (alpha, beta and gamma) and ACTH. This receptor is mediated by G proteins which activate adenylate cyclase.
SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein.
TISSUE SPECIFICITY: Brain, placental, and gut tissues.
POLYMORPHISM: Genetic variations in MC3R define the body mass index quantitative trait locus 9 (BMIQ9) [MIM:602025]. Variance in body mass index is a susceptibility factor for obesity.
SIMILARITY: Belongs to the G-protein coupled receptor 1 family.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
