Melanin-concentrating hormone receptor 2 (MCH₂) also known as G-protein coupled receptor 145 (GPR145) is a protein that in humans is encoded by the MCHR2 gene.^[1][2][3]

MCH₂ is also found in dogs, ferrets, and some other primates and carnivores, but is not found in mice or rats. This has delayed research into the receptor as a therapeutic target, due to most early pharmaceutical research usually being conducted in small mammals such as mice, rats or rabbits which lack the MCH₂ gene and its receptor product.

Clinical Significance

Treatment of human cells expressing MCHR2 with MCH resulted in upregulation of IDH3A, PCK1 and PFKFB4 and the downregulation of INSIG2 and ACOT8.^[4]
