Facts about Melanocortin-2 receptor accessory protein.
Modulator of melanocortin receptors (MC1R, MC2R, MC3R, MC4R and MC5R).
Acts by boosting ligand-sensitivity of melanocortin receptors and enhancing generation of cAMP from the receptors.Desired both for MC2R trafficking to the cell surface of adrenal cells and for signaling in response to corticotropin (ACTH). May be involved in the intracellular trafficking pathways in adipocyte cells.

Expressed in adrenal cortex, testis, breast, thyroid, lymph node, ovary and fat. Expressed in adipose tissues.
Cell membrane; Single-pass membrane protein. Endoplasmic reticulum membrane; Single-pass membrane protein. The formation of antiparallel homo- and heterodimers suggest that N- and C-terminus can both localize in the cytoplasmic and extracellular parts, depending on the context (PubMed:20371771). Upon insulin stimulation, it is redistributed into spotty structures throughout the cytoplasm.
