Gene

• Entrez ID: 4159
• Gene name: Melanocortin 3 receptor
• Gene symbol: MC3R
• Synonyms (NCBI Gene): BMIQ9, MC3, MC3-R, OB20, OQTL
• Chromosome: 20
• Chromosome location: 20q13.2
• Summary: 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 neonata
