Authors: Rulue Chang / Xin Zhang / Anna Qiao / Antao Dai / Matthew J Belousoff / Qiuxiang Tan / Lijun Shao / Li Zhong / Guangyao Lin / Yi-Lynn Liang / Limin Ma / Shuo Han / Dehua Yang / Radostin ...Authors: Rulue Chang / Xin Zhang / Anna Qiao / Antao Dai / Matthew J Belousoff / Qiuxiang Tan / Lijun Shao / Li Zhong / Guangyao Lin / Yi-Lynn Liang / Limin Ma / Shuo Han / Dehua Yang / Radostin Danev / Ming-Wei Wang / Denise Wootten / Beili Wu / Patrick M Sexton / ![]() Abstract: Unimolecular dual agonists of the glucagon (GCG) receptor (GCGR) and glucagon-like peptide-1 receptor (GLP-1R) are a new class of drugs that are potentially superior to GLP-1R-specific agonists for ...Unimolecular dual agonists of the glucagon (GCG) receptor (GCGR) and glucagon-like peptide-1 receptor (GLP-1R) are a new class of drugs that are potentially superior to GLP-1R-specific agonists for the management of metabolic disease. The dual-agonist, peptide 15 (P15), is a glutamic acid 16 analog of GCG with GLP-1 peptide substitutions between amino acids 17 and 24 that has potency equivalent to those of the cognate peptide agonists at the GCGR and GLP-1R. Here, we have used cryo-EM to solve the structure of an active P15-GCGR-G complex and compared this structure to our recently published structure of the GCGR-G complex bound to GCG. This comparison revealed that P15 has a reduced interaction with the first extracellular loop (ECL1) and the top of transmembrane segment 1 (TM1) such that there is increased mobility of the GCGR extracellular domain and at the C terminus of the peptide compared with the GCG-bound receptor. We also observed a distinct conformation of ECL3 and could infer increased mobility of the far N-terminal His-1 residue in the P15-bound structure. These regions of conformational variance in the two peptide-bound GCGR structures were also regions that were distinct between GCGR structures and previously published peptide-bound structures of the GLP-1R, suggesting that greater conformational dynamics may contribute to the increased efficacy of P15 in activation of the GLP-1R compared with GCG. The variable domains in this receptor have previously been implicated in biased agonism at the GLP-1R and could result in altered signaling of P15 at the GCGR compared with GCG. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
