Melanin-concentrating hormone receptor 2 (MCH₂) also known asG-protein coupled receptor 145 (GPR145) is aprotein that in humans is encoded by theMCHR2gene.^[3]^[4]^[5]

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

[edit]

Treatment of human cells expressing MCHR2 withMCH resulted in upregulation ofIDH3A,PCK1 andPFKFB4 and the downregulation ofINSIG2 andACOT8.^[6]
