The adiponectin receptor 1 or ADIPOQ, an essential hormone secreted by adipocytes that regulates glucose and lipid metabolism (Tanabe et al. 2015; Yamauchi et al. 2003. Required for normal glucose and fat homeostasis and for maintaining a normal body weight. ADIPOQ-binding activates a signaling cascade that leads to increased AMPK activity, and ultimately to increased fatty acid oxidation, increased glucose uptake and decreased gluconeogenesis. Has high affinity for globular adiponectin and low affinity for full-length adiponectin. The 3-d structure revealed ceramidase activity for both ADIPOR1 and ADIPOR2; however, the two structures are substantially different (Vasiliauskaité-Brooks et al. 2017).  It may function with adiponectin to stimulate cholesterol efflux via ABCA1 (Hafiane et al. 2019). The Tyr-Pro dipeptide may function as an AdipoR1 agonist (Lee et al. 2021).
