Melanocortins are regulatory peptides derived from post-translational processing of the larger pro-opiomelanocortin (POMC) precursor. Melanocortin-3 Receptor (MC3-R) is a 360 amino acid containing transmembrane protein that belongs to G-protein coupled receptor family and is expressed mainly in adult central nervous system at high levels in a restricted number of neurons of the hypothalamus and the limbic system.
Immunogen
A synthetic peptide corresponding to the N-terminal region of rat melanocortin receptor 3 (amino acids 15-33) coupled to keyhole limpet hemocyanin (KLH). This sequence is highly conserved in mouse MC3-R (89% identity).
Application
Anti-Melanocortin-3 Receptor antibody produced in rabbit has been used in western blotting[1] and immunocytochemistry.
Biochem/physiol Actions
Melanocortin-3 (MC3) receptor has a crucial role in facilitating the effects of the melanocortin system on energy homeostasis. The MC3 receptor has been proposed to mediate the actions of MSH, in particular those of α-MSH and γ-MSH peptides. MC3-R is thought to regulate fat stores by a metabolic pathway. MC3-R knockout mice (MC3-R-/-) have increased fat mass, but not high body mass index, are hyperleptinaemic and develop mild hyperinsulinaemia. In contrast to MC3-R, MC4-R primarily controls food intake, suggesting that both MC3 and MC4 receptors may play a complementary role in weight control.

Corticotropin (ACTH) and melanotropin (MSH) peptides (melanocortins) are produced not only in the pituitary but also in the brain, with highest concentrations in the arcuate nucleus of the hypothalamus and the commisural nucleus of the solitary tract. We have identified

Using the technique of the polymerase chain reaction primed with oligonucleotides based on the homologous transmembrane regions of seven transmembrane G protein-linked receptors, we isolated three full-length human genes that encode a novel subgroup of this receptor family. Recently, two
