The glucagon receptor family is a group of closely related G-protein coupled receptors which include:
Glucagon receptor Glucagon-like peptide 1 receptor Glucagon-like peptide 2 receptor Gastric inhibitory polypeptide receptor
The first three receptors bind closely related peptide hormones (glucagon, glucagon-like peptide-1, glucagon-like peptide-2) derived from the proglucagon polypeptide. The last receptor binds gastric inhibitory polypeptide.
