Background and References

The cystatin superfamily encompasses that contain multiple cystatin-like sequences. Some of the members are active cysteine protease inhibitors, while others have lost or perhaps never acquired this inhibitory activity. There are three inhibitory families in the superfamily, including the type 1 cystatins (stefins), type 2 cystatins and the kininogens. The type 2 cystatin proteins are a class of cysteine proteinase inhibitors found in a variety of human fluids and secretions. The protein is an S-type cystatin, based on its high level of expression in saliva, tears and seminal plasma. The specific role in these fluids is unclear but antibacterial and antiviral activity is present, consistent with a protective function.The cystatin superfamily encompasses proteins that contain multiple BACKGROUND: cystatin-like sequences.

The type 2 cystatin proteins are a class of cysteine proteinase inhibitors found in a variety of human fluids and secretions. The cystatin locus on 20 contains the majority of the type 2 cystatin and pseudogenes. This is located in the cystatin locus and encodes a type 2 salivary cysteine peptidase inhibitor.
