Glycoprotein 2 (also called Pancreatic secretory granule membrane major glycoprotein GP2) is a protein that in humans is encoded by the GP2 gene. This protein is involved in the immune response to type-I-piliated bacteria, binding to bacteria like E. coli in the intestines and delivering them to lymph nodes.
