== Publication Abstract from PubMed ==
G protein-coupled receptors (GPCRs) are key regulators of information transmission between cells and organs. Despite this, we have only a limited understanding of the behavior of GPCRs in the apo state and the conformational changes upon agonist binding that lead to G protein recruitment and activation. We expressed and purified unmodified apo and peptide-bound calcitonin gene-related peptide (CGRP) receptors from insect cells to determine their cryo-electron microscopy (cryo-EM) structures, and we complemented these with analysis of protein conformational dynamics using hydrogen-deuterium exchange mass spectrometry and three-dimensional variance analysis of the cryo-EM data. Together with our previously published structure of the active, Gs-bound CGRP receptor complex, our work provides insight into the mechanisms of class B1 GPCR activation.
