  • 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.
  • Tissue specificity
    Expressed in submandibular and sublingual saliva but not in parotid saliva (at protein level). Expressed in saliva, tears, urine and seminal fluid.
  • Sequence similarities
    Belongs to the cystatin family.
  • Post-translational
    modifications
    Phosphorylated at both its N- and C-terminal regions.
  • Cellular localization
    Secreted.
  • Information by UniProt
