Approximately 30% of known drugs target G protein-coupled receptors (GPCRs), but all the published structures of GPCRs to date are from the class A family of GPCRs; here the first X-ray crystal structure of a member of the class B family of GPCRs, the human corticotropin-releasing factor receptor 1, is determined.
