CC -!- FUNCTION: Receptor for MSH (alpha, beta and gamma) and ACTH. The
CC activity of this receptor is mediated by G proteins which activate
CC adenylate cyclase. Mediates melanogenesis, the production of eumelanin
CC (black/brown) and phaeomelanin (red/yellow), via regulation of cAMP
CC signaling in melanocytes. {ECO:0000250|UniProtKB:Q01726}.
CC -!- SUBUNIT: Interacts with MGRN1, but does not undergo MGRN1-mediated
CC ubiquitination; this interaction competes with GNAS-binding and thus
CC inhibits agonist-induced cAMP production. Interacts with OPN3; the
CC interaction results in a decrease in MC1R-mediated cAMP signaling and
CC ultimately a decrease in melanin production in melanocytes.
CC {ECO:0000250|UniProtKB:Q01726}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:Q01726};
CC Multi-pass membrane protein {ECO:0000255}.
CC -!- SIMILARITY: Belongs to the G-protein coupled receptor 1 family.
CC {ECO:0000255|PROSITE-ProRule:PRU00521}.
