Data Sheet

Background: GPR81 is an orphan G protein-coupled receptor homologous to GPR109A and GPR109B. It is highly expressed in adipose tissues and also regarded as a sensor for Lactate and can mediate an anti-lipolytic effect of lactate. GPR81 can modulate the free fatty acid pool under exercise or conditions of oxygen deficit and is target for the treatment of dyslipidemia and other metabolic disorders.

Application: Functional assays
