Melanin-concentrating hormone receptor 1

Melanin-concentrating hormone receptor 1 (MCHR1) is a protein that in humans is encoded by the MCHR1 gene. It is a G protein-coupled receptor that binds melanin-concentrating hormone (MCH). The primary function of MCHR1 is to regulate energy balance, feeding behavior, and body weight.

Function

MCHR1 is a receptor for melanin-concentrating hormone, a neuropeptide that plays a role in energy homeostasis, feeding behavior, and body weight regulation. MCH acts through MCHR1 to stimulate appetite and reduce metabolic rate, leading to weight gain. MCHR1 is expressed in various regions of the brain, particularly in the hypothalamus, which is a key area for the regulation of feeding and energy balance.

Clinical significance

Alterations in the function of MCHR1 have been implicated in a variety of disorders, including obesity, diabetes, and depression. Given its role in regulating appetite and energy balance, MCHR1 is considered a potential target for the treatment of obesity and related metabolic disorders.

Pharmacology

Several MCHR1 antagonists have been developed for the potential treatment of obesity and related metabolic disorders. These drugs work by blocking the action of MCH at the MCHR1, thereby reducing appetite and increasing metabolic rate.
