HMRbase accession number | 11359 |
Swiss-prot Accession number | P01355 (Sequence in FASTA format) |
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 |
Protein Length | 115 Amino acids |
Molecular weight | 12841 |
