Human GHRHR

Figure. Concentration-dependent activation of GHRHR by GHRH

Reporter cells were transfected with either the expression plasmid for human growth hormone releasing hormone receptor (GHRHR) or the mock plasmid and treated with various concentrations of GHRH. Data points shown are the mean ± SEM of an experiment (n = 3), and the curve is a fit to Hill equation with an EC50 of 2.0 nM.

Glucagon receptor family

The glucagon family of receptors are activated by the endogenous peptide (27-44 aa) hormones glucagon, glucagon-like peptide 1, glucagon-like peptide 2, glucose-dependent insulinotropic polypeptide (also known as gastric inhibitory polypeptide), GHRH and secretin. One common precursor (GCG) generates glucagon, glucagon-like peptide 1 and glucagon-like peptide 2 peptides [1]. For a recent review on the current understanding of the structures of GLP-1 and GLP-1R, the molecular basis of their interaction, and the associated signaling events see de Graaf et al., 2016 [2].
