Melanin-concentrating hormone receptor 2 (MCH
2) also known as G-protein coupled receptor 145 (GPR145) is a
protein that in humans is encoded by the ''MCHR2''
gene.
MCH
2 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 MCH
2 gene and its receptor product.
Clinical significance
Treatment of human cells expressing MCHR2 with
MCH resulted in upregulation of
IDH3A
Isocitrate dehydrogenase ADsubunit alpha, mitochondrial (IDH3α) is an enzyme that in humans is encoded by the ''IDH3A'' gene.
Isocitrate dehydrogenases (IDHs) catalyze the oxidative decarboxylation of isocitrate to 2-oxoglutarate. These enzymes ...

PCK1
Phosphoenolpyruvate carboxykinase 1 (soluble), also known as PCK1, is an enzyme which in humans is encoded by the ''PCK1'' gene.
Function
This enzyme is a main control point for the regulation of gluconeogenesis. The cytosolic enzyme encoded by ...

PFKFB4
6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 4 also known as PFKFB4 is an enzyme which in humans is encoded by the ''PFKFB4'' gene.
Function
The bifunctional 6-phosphofructo-2-kinase ()/fructose-2,6-bisphosphatase () (PFKFB) regulates t ...

INSIG2 and
ACOT8
Acyl-coenzyme A thioesterase 8 is an enzyme that in humans is encoded by the ''ACOT8'' gene.
The protein encoded by this gene is a peroxisomal thioesterase that appears to be involved more in the oxidation of fatty acids rather than in their form ...
