Use at an assay dependent dilution. Predicted molecular weight: 24 kDa.
Has activity against the synthetic substrates Boc-Phe-Ser-Arg-Mec, Boc-Leu-Thr-Arg-Mec, Boc-Gln-Ala-Arg-Mec and Boc-Val-Pro-Arg-Mec. The single-chain form is more active than the two-chain form against all of these substrates.
Involvement in disease
Defects in PRSS1 are a cause of hereditary pancreatitis (HPC) [MIM:167800]; also known as chronic pancreatitis (CP). HPC is an autosomal dominant disease characterized by the presence of calculi in pancreatic ducts. It causes severe abdominal pain attacks.
Belongs to the peptidase S1 family. Contains 1 peptidase S1 domain.
Occurs in a single-chain form and a two-chain form, produced by proteolytic cleavage after Arg-122.
