| Description | Cholecystokinins precursor (CCK) [Contains: Cholecystokinin 39(CCK39); Cholecystokinin 33 (CCK33); Cholecystokinin 22 (CCK22);Cholecystokinin 12 (CCK12); Cholecystokinin 8 (CCK8)]. |
| Source organism | Rattus norvegicus (Rat) |
| Taxonomical Classification | Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi;Mammalia; Eutheria; Euarchontoglires; Glires; Rodentia; Sciurognathi;Muroidea; Muridae; Murinae; Rattus. |
| Subcellular location | Secreted |
| Developmental Stage | N/A |
| Similarity | Belongs to the gastrin/cholecystokinin family. |
| Tissue Specificity | The shortest form (CCK8) is predominantly found in the brain, whereas the larger ones are found in the intestine |
| Post translational modification | Cholecystokinin, also known as CCK58, is proteolytically cleaved to produce a number of active cholecystokinins. Sulfation of Tyr-97 is essential for receptor activation. |
| Function | 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 |
