Swissprots	P01037 Q9UCQ6 Q96LE6
Accessions	AAA36115 EAX10134 P01037 BC021225 AAH21225 J03870 AAA60299 NM_001898 NP_001889
Function	Human saliva appears to contain several cysteine proteinase inhibitors that are immunologically related to cystatin S but that differ in their specificity due to amino acid sequence differences. Cystatin SN, with a pI of 7.5, is a much better inhibitor of papain and dipeptidyl peptidase I than is cystatin S, although both inhibit ficin equally well.
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}.
