A role for cholecystokinin-stimulated protein tyrosine phosphorylation in regulated secretion by the pancreatic acinar cell.


Cholecystokinin (CCK) is a gastrointestinal hormone that acts through a G protein-coupled receptor to stimulate pancreatic enzyme secretion. In this work, we demonstrate that CCK stimulation of dispersed pancreatic acini results in increased tyrosine phosphorylation of several cellular proteins. This is mediated via a calcium-dependent pathway, also… (More)
