Ma et al. (2020) and Liang et al. (2020) describe the cryo-EM structures of three class B G protein-coupled receptors (GPCRs) in complex with native peptides and Gs. Their work establishes the structural basis of peptide specificity and a conserved mechanism of receptor activation and G protein coupling for class B GPCRs.
马等人(2020 年)和梁等人(2020 年)描述了三种与天然肽和 Gs 复合物的 B 类 G 蛋白偶联受体(GPCR)的冷冻电镜结构。他们的工作为 B 类 GPCR 的肽特异性和受体激活以及 G 蛋白偶联的保守机制奠定了结构基础。
