Swissprots	Q9UCS9 Q9UBI5 P01036
Accessions	AAB24493 AAK11571 EAX10135 P01036 BC065714 AAH65714 BC074952 AAH74952 BC074953 AAH74953 HQ447582 ADQ32068 X54667 CAA38478 NM_001899 NP_001890
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.
Subcellular Location	Secreted {ECO:0000269|PubMed:20189825}.
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}.
