| Description | Cholecystokinins precursor (CCK) [Contains: Cholecystokinin 70(CCK70); Cholecystokinin 8 (CCK8); Cholecystokinin 7 (CCK7)]. |
| Source organism | Gallus gallus (Chicken) |
| Taxonomical Classification | Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi;Archosauria; Dinosauria; Saurischia; Theropoda; Coelurosauria; Aves;Neognathae; Galliformes; Phasianidae; Phasianinae; Gallus. |
| Subcellular location | Secreted |
| Developmental Stage | N/A |
| Similarity | Belongs to the gastrin/cholecystokinin family. |
| Tissue Specificity | In the small intestine, the major production site is around the vitelline diverticulum |
| Post translational modification | The precursor is cleaved by enzymes to produce a number of active cholecystokinins. |
| 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. It also decreases food intake and regulates gastrointestinal physiological processes. |
| Protein Length | 130 Amino acids |
