Adiponectin receptor 1 (AdipoR1) is a protein which in humans is encoded by the ADIPOR1 gene. [5] It is a member of the progestin and adipoQ receptor (PAQR) family, and is also known as PAQR1. [6]
Similar to G protein-coupled receptors (GPCRs), AdipoR1 also possesses 7 transmembrane domains. However, AdipoR1 is orientated oppositely to GPCRs in the membrane (i.e., cytoplasmic N-terminus, extracellular C-terminus) and does not associate with G proteins. [5]
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. [5] [7] In 2016, the University of Tokyo announced that it would launch an investigation into claims of fabrication of AdipoR1 and AdipoR2 identification data, as accused by an anonymous person/group called Ordinary_researchers.
