Melanocortin receptors in leptin effects [PDF]
Nature, 1997 Leptin acts on the central nervous system to cause a reduction in food intake and body weight1,2. The melanocortin system in the brain is also implicated in energy homeostasis, with agonists of the melanocortin-4 (MC4) receptor reducing food intake3 and targeted mutation of the MC4 receptor causing obesity4.

The melanocortin pathway and energy homeostasis: From discovery to obesity therapy
Molecular Metabolism, 2021 Background: Over the past 20 years, insights from human and mouse genetics have illuminated the central role of the brain leptin-melanocortin pathway in controlling mammalian food intake, with genetic disruption resulting in extreme obesity, and more ...

The Multifaceted Melanocortin Receptors
Endocrinology, 2022 AbstractThe 5 known melanocortin receptors (MCs) have established physiological roles. With the exception of MC2, these receptors can behave unpredictably, and since they are more widely expressed than their established roles would suggest, it is likely that they have other poorly characterized functions.

Melanocortin receptor 3 and 4 mRNA expression in the adult female Syrian hamster brain
Frontiers in Molecular Neuroscience, 2023 Melanocortin 3 receptors (MC3R) and melanocortin 4 receptors (MC4R) are vital in regulating a variety of functions across many species. For example, the dysregulation of these receptors results in obesity and dysfunction in sexual behaviors.

Identification of novel GPCR partners of the central melanocortin signaling
Molecular Metabolism, 2021 Objective: Homo- or heterodimerization of G protein–coupled receptors (GPCRs) generally alters the normal functioning of these receptors and mediates their responses to a variety of physiological stimuli in vivo.

MOLECULAR EVOLUTION OF GPCRS: Melanocortin/melanocortin receptors [PDF]
Journal of Molecular Endocrinology, 2014 The melanocortin receptors (MCRs) are a family of G protein-coupled receptors that are activated by melanocortin ligands derived from the proprotein, proopiomelanocortin (POMC). During the radiation of the gnathostomes, the five receptors have become functionally segregated (i.e.

Differential Signaling Profiles of MC4R Mutations with Three Different Ligands [PDF]
, 2020 The melanocortin 4 receptor (MC4R) is a key player in hypothalamic weight regulation and energy expenditure as part of the leptin-melanocortin pathway. Mutations in this G protein coupled receptor (GPCR) are the most common cause for monogenetic obesity,

Frontiers in Neuroscience, 2013 The melanocortin receptors are a gene family in the rhodopsin class of G protein-coupled receptors. Based on the analysis of several metazoan genome databases it appears that the melanocortin receptors are only found in chordates.

Melanocortin 4 receptor signaling in Sim1 neurons permits sexual receptivity in female mice
Frontiers in Endocrinology, 2023 IntroductionFemale sexual dysfunction affects approximately 40% of women in the United States, yet few therapeutic options exist for these patients. The melanocortin system is a new treatment target for hypoactive sexual desire disorder (HSDD), but the ...
