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
modificationsPhosphorylated at both its N- and C-terminal regions. -
Cellular localization
