High-resolution structural studies on G-protein-coupled receptors (GPCRs) have flourished recently, providing long-sought insights into the dynamic process of guanine nucleotide-binding protein (G-protein) activation. In parallel, analogous studies are starting to shed light on how the same G-proteins are activated by non-GPCR proteins. Can we learn about common themes and variations in G-protein activation from them?
高分辨率结构研究最近在 G 蛋白偶联受体 (GPCR) 领域蓬勃发展,为长期以来人们对鸟苷酸结合蛋白 (G 蛋白) 激活的动态过程的理解提供了深入的见解。与此同时,类似的研究也开始揭示同样的 G 蛋白如何被非 GPCR 蛋白激活。我们能否从这些研究中了解 G 蛋白激活的共同主题和变化?
