The progestin and adipoQ receptor (PAQR) family is a group of receptors related to but distinct from the G protein-coupled receptor family, which have the similar seven transmembrane structure, but the N-terminal is located on the inner side of the cell.[1] It includes at least 11 receptors (PAQR1–PAQR11), including the adiponectin (adipoQ) receptors (AdipoRs), the membrane progesterone receptors (mPRs), and others.[1]
In 2016, the University of Tokyo announced that it would launch an investigation into claims of fabrication of AdipoRs identification data, as accused by an anonymous person/group called Ordinary_researchers.[2]
