Background
Pancreatic secretory granule membrane major glycoprotein (GP2) is the most abundant membrane component of zymogen granules secreted by pancreatic acinar cells. GP2 associates with the plasma membrane via glycosylphosphatidylinositol (GPI) linkage. It is released from the membrane of mature zymogen granules by an enzymatic mechanism. GP2 plays a role in defense against adhesive and invasive commensal bacteria during intestinal inflammation. GP2 is preferentially expressed in acinar cell carcinomas of the pancreas but the glycoprotein can rarely also be expressed in a variety of other tumor entities. The apparent molecular weight of GP2 is 70-100 kDa, which is larger than the calculated molecular weight, due to glycosylation.
