Descripción general
Cholecystokinin Octapeptide (CCK-8), desulfated is a synthetic desulfated octapeptides of Cholecystokinin (CCK).
Cholecystokinin Octapeptide (CCK-8), desulfated has been used in the specificity testing against gastrin and pepsinogen I proteins.
Biochem/physiol Actions
Cholecystokinin (CCK) is a 115 amino acid preprohormone and a neurotransmitter. It exists in many isoforms. The octapeptide of CCK (CCK-8S) is the most abundant form. CCK is mapped to human chromosome 3p22.1. CCK interacts with receptors of the gastrointestinal tract and nervous system. Polymorphisms in the CCK is implicated in hallucinations in patients with Parkinson′s disease. CCK plays a key role in the activation of the calcineurin-regulated nuclear factor of activated T-cells (NFATs).
Biologically inactive form of CCK-8; CCKB/gastrin receptor agonist that has no activity at the CCKA receptor.
