Trypsin-1 (PRSS1)

Target: PRSS1
Molecular classification: Enzyme, Serine protease, Serine endopeptidase

Overview

Trypsin-1 (PRSS1), also known as cationic trypsinogen, is a serine protease enzyme that plays a crucial role in protein digestion. Synthesized in the pancreas as an inactive precursor, it is activated in the small intestine to its mature form, trypsin. Trypsin-1 cleaves peptide bonds at lysine or arginine residues and activates other proenzymes involved in digestion. Mutations in PRSS1 are associated with hereditary pancreatitis.

Other names: Cationic trypsinogenTRP1TRY1TRY4TRYP1Protease serine 1Serine protease 1

Mechanism of action

Not applicable, PRSS1 is usually indirectly targeted by managing its downstream effects or activity through other mechanisms.

Biological functions

Protein digestionActivation of other digestive enzymesCleavage of peptide bonds

Disease associations

Hereditary pancreatitis

Safety considerations

Premature activation leading to autodigestion of the pancreasPotential for pancreatic inflammation and damageRisk of maldigestion due to loss of exocrine function
