Receptor for ADIPOQ, an essential hormone secreted by adipocytes that regulates glucose and lipid metabolism (PubMed:25855295, PubMed:12802337). 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 (By similarity). May form homooligomers and heterooligomers with ADIPOR2 (PubMed:12802337). Interacts with APPL2 (via BAR domain); hinders the accessibility of APPL1 to ADIPOR1; negatively regulates adiponectin signaling; ADIPOQ dissociates this interaction and facilitates the recruitment of APPL1 to ADIPOR1. Interacts with APPL1; ADIPOQ enhances this interaction; inhibites adiponectin-stimulated binding of APPL2 to ADIPOR1 (By similarity). Localized to the cell membrane and intracellular organelles. Widely expressed (PubMed:16044242). Highly expressed in heart and skeletal muscle (PubMed:12802337). Expressed at intermediate level in brain, spleen, kidney, liver, placenta, lung and peripheral blood leukocytes (PubMed:12802337). Weakly expressed in colon, thymus and small intestine (PubMed:12802337). The N-terminus is cytoplasmic and the C-terminus is extracellular, contrary to what is observed for G-protein coupled receptors. Unlike G-protein coupled receptors, transmembrane helices are not kinked or tilted relative to the plane of the membrane. Belongs to the ADIPOR family.
