Disease

TRY1_HUMAN Defects in PRSS1 are a cause of pancreatitis (PCTT) [MIM:167800. A disease characterized by the presence of calculi in pancreatic ducts. It causes severe abdominal pain attacks.[1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11]

Function

TRY1_HUMAN 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.[12]
