ABSTRACT
G protein-coupled receptors(GPCRs)represent the largest class of cell surface receptors,mediating wide range of cellular and physiological processes through their transducers,G proteins and the-arrestins participate in almost all pathological processes. Recent technological advances are revolutionizing the utility of cryo-electron microscopy(cryo-EM),leading to a tremendous progress in the structural studies of biological macromolecules and cryo-EM has played a leading role in the structural biology of GPCR signaling complex. New discoveries of high-resolution threedimensional structures of GPCR signaling complexes based on cryo-EM have emerged vigorously,which depict the common structural characteristics of intermolecular interaction between GPCR and G protein complex-the conformational changes of the transmembrane helix 6 of receptors,and also demonstrate the structural basis of G protein subtype selectivity. Single-particle cryo-EM becomes an efficient tool for identifying the molecular mechanism of receptor-ligand interaction,providing important information for understanding GPCR signaling and the structure-based drug design.
