This peptide hormone induces gall bladder contraction and the release of pancreatic enzymes in the gut. Its function in the brain is not clear. Binding to CCK-A receptors stimulates amylase release from the pancreas, binding to CCK-B receptors stimulates gastric acid secretion.

The precursor is cleaved by proteases to produce a number of active cholecystokinins. Brain contains CCK-octapeptide (CCK8) and several CCK-desoctapeptides; whereas pig gut contains intact CCK33, CCK39, and CCK58 as well as CCK-octapeptide and the CCK-desoctapeptides. Distribution differences are due to tissue-specific post-translational processing events.
