The GPCR Network was established in 2010 with the aim of structurally characterizing 15–25 representative human G protein-coupled receptors (GPCRs) within 5 years; so far, more than eight have been determined. Here, Stevens and colleagues provide an overview of this collaborative effort and the challenges remaining in gaining detailed insights into the structure–function relationships of this receptor superfamily.
