Adiponectin receptor 2 (AdipoR2) is a protein which in humans is encoded by the ADIPOR2 gene.[1] It is a member of the progestin and adipoQ receptor (PAQR) family, and is also known as PAQR2.[2]


Similar to G protein-coupled receptors (GPCRs), AdipoR2 also possesses 7 transmembrane domains. However, AdipoR2 is orientated oppositely to GPCRs in the membrane (i.e., cytoplasmic N-terminus, extracellular C-terminus) and does not associate with G proteins.[1]


The adiponectin receptors, AdipoR1 and AdipoR2, serve as receptors for globular and full-length adiponectin and mediate increased AMPK and PPAR-α ligand activities, as well as fatty acid oxidation and glucose uptake by adiponectin.[1] In 2016, the University of Tokyo announced it was launching an investigation into anonymously made claims of fabricated and falsified data on the identification of AdipoR1 and AdipoR2.[3]
