27111510 2.5 A crystal structure of human GCGR in complex with the antagonist MK-0893, which is found to bind to an allosteric site outside the seven transmembrane helical bundle in a position between TM6 and TM7 extending into the lipid bilayer
26227798 Molecular dynamics and disulfide crosslinking studies suggest that apo-GCGR can adopt both an open and closed conformation associated with extensive contacts between the ECD and 7TM domain. Glucagon binds to GCGR by a conformational selection mechanism.

20647307 substituted cysteine accessibility method and 3D-molecular modeling to study the N-terminal domain; results showed that Asp(63), Arg(116), and Lys(98) are essential for the receptor structure and/or ligand binding
19903011 The [Ca2+] response is induced by glucagon mainly via the coupling of GCGR to the Galphaq/11 and Galphai/o proteins.

19051206 An analysis of some of these sequences shows that TCR from both human diabetics and NOD mice mimic insulin, glucagon, the insulin receptor, and the glucagon receptor.
17374560 Expression of peroxisome proliferator-activated receptor gamma coactivator 1alpha (PGC-1alpha), known to be upregulated in the liver by fasting, was found to abolish the cAMP-dependent downregulation of glucagon receptor mRNA expression in vitro.
12724331 Three distinct epitopes on the extracellular face of the glucagon receptor determine specificity for the glucagon amino terminus
12536714 Observational study of gene-disease association. (HuGE Navigator)
11961492 Gly40Ser mutation in the glucagon receptor gene is not associated with type 2 diabetes in a Brazilian population, but a reduction of insulin secretion was observed in Gly40Ser carriers.
