Function

function

Receptor specific to the heptapeptide core common to adrenocorticotropic hormone and alpha-, beta-, and gamma-MSH. Plays a central role in energy homeostasis and somatic growth. This receptor is mediated by G proteins that stimulate adenylate cyclase (cAMP).

Interaction

Subunit

Interacts with ATRNL1. Homodimer; disulfide-linked, also forms higher order oligomers. Interacts with MGRN1, but does not undergo MGRN1-mediated ubiquitination; this interaction competes with GNAS-binding and thus inhibits agonist-induced cAMP production. Interacts with MRAP and MRAP2; these associated factors increase ligand-sensitivity and generation of cAMP.
