Thr312 and Ser329/330 in the C-terminal tail of MC4R are potential sites for PKA and GRK phosphorylation and the subsequent recruitment of β-arrestin to the activated receptor. Replacement by alanine(s) of Thr312 and Ser329/330 in the C-terminal tail resulted in an impaired sequestration of mutated receptors to agonist, whereas mutations of Thr232 or Ser306 did not. This indicates that phosphorylation of these residues by kinases is critical for the internalization of MC4R. |

Enhanced melanocortin signaling in the hypothalamus results in both decreased food intake and increased energy expenditure. Adipose tissue derived hormone leptin induces negative energy balance by stimulating α-MSH and melanocortin-4 receptor (MC4R) (Friedman 1997, Kask et al. 1998). Increased melanocortin signaling in hypotalamus leads not only to decreased food intake but also increases sympathetic nervous system outflow to skeletal muscle, energy expenditure and physical activity |

The melanocortin (MC) receptor family consists of five Gs-coupled receptors that control various physiological functions in response to four distinct agonists, adrenocorticotropic hormone (ACTH, also known as corticotrophin) and alpha, beta, and gamma melanocyte-stimulating hormone (MSH), which are derived from the proopiomelanocortin precursor protein, and two inverse agonists, agouti and agouti-related proteins |

We report that MRAP and MRAP2 can interact with all 5 MCRs. This interaction results in MC2R surface expression and signaling. In contrast, MRAP and MRAP2 can reduce MC1R, MC3R, MC4R, and MC5R responsiveness to [Nle4,D-Phe7]alpha-melanocyte-stimulating hormone (NDP-MSH). MRAP and MRAP2 can reduce the surface expression of MC4R and also the signaling of this receptor. we observed a significant decrease in the cell-surface expression of MC4R and MC5R in the presence of MRAP and MRAP2. It is interesting that MRAP and MRAP2 have opposite effects in the modulation of different MCR family members. |
