Introduction
Trypsin-1, which belongs to the trypsin family of serine proteases, is localized to the T cell receptor beta locus on chromosome 7. Trypsin-1 is secreted by the pancreas and cleaved to its active form in the small intestine. Trypsin-1 operates on peptide linkages involving the carboxyl group of lysine or arginine. Alterations are the cause for hereditary pancreatitis.
