![]() | ![]() タイトル: Structure of a D2 dopamine receptor-G-protein complex in a lipid membrane. 著者: Jie Yin / Kuang-Yui M Chen / Mary J Clark / Mahdi Hijazi / Punita Kumari / Xiao-Chen Bai / Roger K Sunahara / Patrick Barth / Daniel M Rosenbaum / ![]() ![]() 要旨: The D2 dopamine receptor (DRD2) is a therapeutic target for Parkinson's disease and antipsychotic drugs.

DRD2 is activated by the endogenous neurotransmitter dopamine and synthetic agonist drugs such as bromocriptine, leading to stimulation of G and inhibition of adenylyl cyclase. Here we used cryo-electron microscopy to elucidate the structure of an agonist-bound activated DRD2-G complex reconstituted into a phospholipid membrane. The extracellular ligand-binding site of DRD2 is remodelled in response to agonist binding, with conformational changes in extracellular loop 2, transmembrane domain 5 (TM5), TM6 and TM7, propagating to opening of the intracellular G-binding site. The DRD2-G structure represents, to our knowledge, the first experimental model of a G-protein-coupled receptor-G-protein complex embedded in a phospholipid bilayer, which serves as a benchmark to validate the interactions seen in previous detergent-bound structures. The structure also reveals interactions that are unique to the membrane-embedded complex, including helix 8 burial in the inner leaflet, ordered lysine and arginine side chains in the membrane interfacial regions, and lipid anchoring of the G protein in the membrane. Our model of the activated DRD2 will help to inform the design of subtype-selective DRD2 ligands for multiple human central nervous system disorders. | ||||||
