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).
