Citation | Journal: Nat Commun / Year: 2022 Title: Structural basis of adhesion GPCR GPR110 activation by stalk peptide and G-proteins coupling. Authors: Xinyan Zhu / Yu Qian / Xiaowan Li / Zhenmei Xu / Ruixue Xia / Na Wang / Jiale Liang / Han Yin / Anqi Zhang / Changyou Guo / Guangfu Wang / Yuanzheng He / Abstract: Adhesion G protein-coupled receptors (aGPCRs) are keys of many physiological events and attractive targets for various diseases. aGPCRs are also known to be capable of self-activation via an ...Adhesion G protein-coupled receptors (aGPCRs) are keys of many physiological events and attractive targets for various diseases. aGPCRs are also known to be capable of self-activation via an autoproteolysis process that removes the inhibitory GAIN domain on the extracellular side of receptor and releases a stalk peptide to bind and activate the transmembrane side of receptor. However, the detailed mechanism of aGPCR activation remains elusive. Here, we report the cryo-electron microscopy structures of GPR110 (ADGRF1), a member of aGPCR, in complex with G, G, G, G and G The structures reveal distinctive ligand engaging model and activation conformations of GPR110. The structures also unveil the rarely explored GPCR/G and GPCR/G engagements. A comparison of G, G, G, G and G engagements with GPR110 reveals details of G-protein engagement, including a dividing point at the far end of the alpha helix 5 (αH5) of Gα subunit that separates G/G engagements from G/G/G engagements. This is also where G/G bind the receptor through both hydrophobic and polar interaction, while G/G/G engage receptor mainly through hydrophobic interaction. We further provide physiological evidence of GPR110 activation via stalk peptide. Taken together, our study fills the missing information of GPCR/G-protein engagement and provides a framework for understanding aGPCR activation and GPR110 signaling. | ||||||
