[edit] Description
Cholecystokinins precursor (CCK8) [Contains: Cholecystokinin 8 (CCK8);Cholecystokinin 12 (CCK12); Cholecystokinin 26 (CCK26);Cholecystokinin 36 (CCK36); Cholecystokinin 69 (CCK69)].
[edit] Source Organism
Carassius auratus (Goldfish).
[edit] Taxomomy
Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi;Actinopterygii; Neopterygii; Teleostei; Ostariophysi; Cypriniformes;Cyprinidae; Carassius.
[edit] Subcellular Localization
Secreted (Potential).
[edit] Developmental Stage
Expression in the brain shows variation throughout the seasonal sexual cycle; in the optic tectum-thalamus of females, expression levels are lower in early gonadal recrudescence (October) compared to other sexual stages. In males, expression is high in the olfactory bulbs in early gonadal recrudescence and low in the posterior brain in late gonadal recrudescence (January). Expression is higher in females than males in the telencephalon-preoptic region and posterior brain during late gonadal recrudescence, and in the olfactory bulbs and optic tectum-thalamus during the sexually mature (April), and post-spawning and sexually regressed (July) stages.
[edit] Similarity
Belongs to the gastrin/cholecystokinin family.
[edit] Post translational Modification
The precursor is cleaved by enzymes to produce a number of active cholecystokinins (By similarity).
[edit] Function
This peptide hormone induces gall bladder contraction and the release of pancreatic enzymes in the gut (By similarity). Induces the secretion of gonadotropin and growth hormone from the pituitary. Suppresses food intake and decreases the expression of preprosomatostatin genes in the forebrain
