What's The Definition Of The Medical Condition Receptor, Gastrin?
Cell surface proteins that bind cholecystokinin (CCK) with high affinity and trigger intracellular changes influencing the behavior of cells. Cholecystokinin receptors are activated by gastrin as well as by CCK-4; CCK-8; and CCK-33. Activation of these receptors evokes secretion of amylase by pancreatic acinar cells, acid and pepsin by stomach mucosal cells, and contraction of the pylorus and gall bladder. The role of the widespread CCK receptors in the central nervous system is not well understood.
