Cystatin-S is a protein that in humans is encoded by the CST4 gene.[1][2]

The cystatin superfamily encompasses proteins 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 cystatin locus on chromosome 20 contains the majority of the type 2 cystatin genes and pseudogenes. This gene is located in the cystatin locus and encodes a type 2 salivary cysteine peptidase inhibitor. 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.[2]

Transcriptions

The "four cystatin genes [GeneID: 1469 CST1, GeneID: 1470 CST2, GeneID: 1471 CST3, and GeneID: 1472 CST4] contain the ATA-box sequence (ATAAA) in their 5'-flanking regions; however, the CAT-box sequence (CAT), a binding site of the transcription factor, CTF, is found only in the 5'-flanking region of the S-type cystatin genes."[3]
