GPR81
Introduction
G protein-coupled receptor 81, also known as GPR81, is a protein that in humans is encoded by the GPR81 gene.[1][2]
G protein-coupled receptors (GPCRs, or GPRs), such as GPR81, contain 7 transmembrane domains and transduce extracellular signals through heterotrimeric G proteins.[1]
Lactate activates the GPR81 receptor which in turn inhibits lipolysis in fat cells.[3][4]
