Author information




H.M. carried out construct preparation, protein expression and purification and prepared the cryo-EM sample. H.M. and D.Y. collected the data. D.Y. processed cryo-EM data, modeled, refined and analyzed the structure, wrote manuscript with input from all authors. W.H. performed molecular docking. L.Z. designed the expression constructs for the compound–GLP-1R–Gs complex. X.W. purified the Nb35 nanobody and performed specimen screening by negative-stain EM. Y.J. assisted in construct preparation, protein expression, and purification. F.L. oversaw cell experiments. W.G. and X.S. assisted with model building. H.E.X. and W.Z. conceived of the project, W.Z. designed RGT1383, and H.E.X. supervised the overall structural studies and participated in manuscript writing.
