引用 | ジャーナル: Elife / 年: 2018タイトル: Cryo-EM structure of the adenosine A receptor coupled to an engineered heterotrimeric G protein. 著者: Javier García-Nafría / Yang Lee / Xiaochen Bai / Byron Carpenter / Christopher G Tate / ![]() 要旨: The adenosine A receptor (AR) is a prototypical G protein-coupled receptor (GPCR) that couples to the heterotrimeric G protein G. Here, we determine the structure by electron cryo-microscopy (cryo-EM) ...The adenosine A receptor (AR) is a prototypical G protein-coupled receptor (GPCR) that couples to the heterotrimeric G protein G. Here, we determine the structure by electron cryo-microscopy (cryo-EM) of AR at pH 7.5 bound to the small molecule agonist NECA and coupled to an engineered heterotrimeric G protein, which contains mini-G, the βγ subunits and nanobody Nb35. Most regions of the complex have a resolution of ~3.8 Å or better. Comparison with the 3.4 Å resolution crystal structure shows that the receptor and mini-G are virtually identical and that the density of the side chains and ligand are of comparable quality. However, the cryo-EM density map also indicates regions that are flexible in comparison to the crystal structures, which unexpectedly includes regions in the ligand binding pocket. In addition, an interaction between intracellular loop 1 of the receptor and the β subunit of the G protein was observed. | |||||||||
