Description; Amino Acid Sequence; Boc-Bal-Trp-Met-Asp-Phe-NH2; General description; CCK2R (cholecystokinin 2 receptor) is also referred as CCKBR. It is a G-protein coupled receptor, that is expressed in the central nervous system and throughout the gastrointestinal tract.[1] CCK2R is located on human 11p15.[2]; Application; Pentagastrin has been used to bidirectionally modulate lateral nucleus of the amygdala (LA) activity.[3]; Packaging; 25, 100 mg in serum bottle; Biochem/physiol Actions; CCKB agonist that stimulates gastric acid secretion; anxiogenic. Pentagastrin is an agonist of the cholecystokinin-2 (CCK2) receptor. It helps to increase the excitability of neurons in the basolateral amygdala through the activation of a non-specific cation channel.[3]
