  Function in Host
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 formagainst all of these substrates. [1]

Function of This Protein During Virus Infection
Virus NameSARS-COV-2 Protein Function Anti-viral [2]
Infected TissueLung Infection Time24h; 48 h
Infected CellCalu-3 cells (Human lung cancer cell line) Cellosaurus IDCVCL_0609 
Method DescriptionTo detect the role of host protein PRSS1 in viral infection, PRSS1 protein knockout Calu-3 cells were infected with SARS-COV-2 for 24 - 48 h , and the effects on infection was detected through qRT-PCR.
ResultsIt is reported that Knockdown of PRSS1 increases SARS-CoV-2 RNA levels compared with control group.
