of G protein-coupled receptors and the structural features that are responsible for the various functions ascribed to cell-surface receptors, particularly it emphasizes on the 尾-adrenergic receptor, because it, along with rhodopsin, is the most extensively studied of the G protein-coupled receptors....
Targeting G protein-coupled receptors (GPCRs) in metabolic tissues — such as adipose tissue, liver, muscle, pancreatic islets, immune cells and the central nervous system — has emerged as a key target for current and future anti-diabetic compounds. This Opinion focuses on the potential of ...
G protein-coupled receptors (GPCRs) are unique integral membrane proteins comprising seven transmembrane helical regions with an N-terminal region (extracellular), a C-terminal region (cytosolic), and three loops on each of the interior and exterior faces of the cell membrane. ...
