Background: Trypsin 1/PRSS1

Human Trypsin 1, encoded by the PRSS1 gene, is also known as cationic trypsinogen (1). Constituting approximately two‑thirds of the total trypsin content in normal pancreatic juice, it is the most abundant trypsin isoform produced by the pancreas. It contains a signal peptide (residues 1‑15), a pro region (residues 16‑23), and a mature chain (residues 24‑247). Trypsin 1 is synthesized in the pancreas and secreted into the duodenum lumen, where it is activated by enterokinase. Its major physiologic function is to digest food and to activate other pro‑enzymes (2). Mutations in the PRSS1 gene can cause hereditary pancreatitis (3).
