Residues in the second extracellular loop (e2) play a role in ligand binding in certain aminergic G protein coupled receptors (GPCRs). N-[3-(1H-Imidazol-4-yl)propyl)]guanidines and N G-acylated derivatives are more efficacious and potent agonists at fusion proteins of the guinea pig histamine H2 receptor and the short splice variant of Gsα, GsαS (gpH2R-GsαS) than at the human isoform ...
