![]() | ![]() タイトル: Structural basis for chemokine recognition and receptor activation of chemokine receptor CCR5. 著者: Hui Zhang / Kun Chen / Qiuxiang Tan / Qiang Shao / Shuo Han / Chenhui Zhang / Cuiying Yi / Xiaojing Chu / Ya Zhu / Yechun Xu / Qiang Zhao / Beili Wu / ![]() 要旨: The chemokine receptor CCR5 plays a vital role in immune surveillance and inflammation. However, molecular details that govern its endogenous chemokine recognition and receptor activation remain ...The chemokine receptor CCR5 plays a vital role in immune surveillance and inflammation. However, molecular details that govern its endogenous chemokine recognition and receptor activation remain elusive. Here we report three cryo-electron microscopy structures of G protein-coupled CCR5 in a ligand-free state and in complex with the chemokine MIP-1α or RANTES, as well as the crystal structure of MIP-1α-bound CCR5. These structures reveal distinct binding modes of the two chemokines and a specific accommodate pattern of the chemokine for the distal N terminus of CCR5. Together with functional data, the structures demonstrate that chemokine-induced rearrangement of toggle switch and plasticity of the receptor extracellular region are critical for receptor activation, while a conserved tryptophan residue in helix II acts as a trigger of receptor constitutive activation. | |||||||||
