Summaries for CCK Gene

Entrez Gene Summary for CCK Gene

  • This gene encodes a member of the gastrin/cholecystokinin family of proteins. The encoded preproprotein is proteolytically processed to generate multiple protein products, including the peptide hormones cholecystokinin-8, -12, -33, and others. The encoded peptides have been shown to regulate gastric acid secretion and food intake. A sulfated form of cholecystokinin-8 may modulate neuronal activity in the brain. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2015]

GeneCards Summary for CCK Gene

CCK (Cholecystokinin) is a Protein Coding gene. Diseases associated with CCK include cholecystitis and bulimia nervosa. Among its related pathways are Signaling by GPCR and Interleukin-3, 5 and GM-CSF signaling. GO annotations related to this gene include hormone activity and neuropeptide hormone activity.

UniProtKB/Swiss-Prot for CCK Gene

  • 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.

Tocris Summary for CCK Gene

  • Cholecystokinin (CCK) is a neuropeptide and gut hormone that regulates pancreatic enzyme secretion and gastrointestinal motility, and acts as a satiety signal. It is released simultaneously from intestinal cells and neurons in response to a meal. The precursor molecule prepro-CCK can be cleaved to generate a variety of biologically active forms of CCK including CCK-33, CCK-8 (CCK octapeptide), CCK-39 and CCK-58. Two CCK receptor subtypes, CCK1 and CCK2, mediate the physiological actions of CCK and the related peptide gastrin. The CCK1 receptor has a high affinity for sulfated CCK analogs, whereas the CCK2 receptor has similar affinity for sulfated and non-sulfated forms.
