Background
| Function | FUNCTION: This protein strongly inhibits papain and ficin, partially inhibits stem bromelain and bovine cathepsin C, but does not inhibit porcine cathepsin B or clostripain. Papain is inhibited non-competitively. |
| Pathway | |
| Protein Families | Cystatin family |
| Tissue Specificity | Expressed in submandibular and sublingual saliva but not in parotid saliva (at protein level). Expressed in saliva, tears, urine and seminal fluid. {ECO:0000269|PubMed:20189825}. |
