The melanocortin 2 receptor accessory protein (MRAP) was originally discovered to be an essential co-receptor for the ACTH receptor/melanocortin 2 receptor, and it physically interacts with this receptor and is required for receptor trafficking and ligand binding. A related molecule, MRAP2, is mainly expressed in the CNS and appears to have a role with the melanocortin 4 receptor. Consistent with this is the observation that a massively obese phenotype develops when the Mrap2 gene is deleted in mice. However, the characteristics of this phenotype differ from those of Mc4r deleted mice, and suggest that an additional role, possibly resulting from an interaction with other receptors is possible. In support of this, a functional interaction with the prokineticin receptors was recently reported. Evidence for other receptor interactions and aspects of the tissue distribution of MRAP and MRAP2 gene expression may indicate that these accessory proteins have a wider role than with the melanocortin receptors alone.
