Extending the Structural View of Class B GPCRs

Methodological developments in X-ray crystallography and cryo-electron microscopy have enabled the determination of the first full-length and G protein-coupled structures of class B G protein-coupled receptors (GPCRs). Structural comparison of different class B GPCR–ligand complexes provides insights into the molecular mechanisms of receptor activation, including: (i) ligand-induced conformational changes of extracellular and transmembrane...
