Glucagon/gastric inhibitory polypeptide/secretin/vasoactive intestinal peptide hormones are a family of evolutionarily related peptide hormones that regulate activity of G-protein-coupled receptors from the secretin receptor family. A number of polypeptidic hormones, mainly expressed in the intestine or the pancreas, belong to a group of these structurally related peptides.[1][2]

This family of hormones are produced from (preproglucagon), which is cleaved to produce glucagon, glucagon-like protein I, glucagon-like protein II, and glicentin.[3] Other members of the structurally similar group include secretin, gastric inhibitory peptide, vasoactive intestinal peptide, prealbumin, peptide HI-27, and growth hormone releasing factor.

One hormone, glucagon, is fully conserved in all mammalian species in which it has been studied.[4]
