Cystatin sn
Cystatin-SN is a protein that in humans is encoded by the CST1 gene. 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.

The cysteine protease activity of house dust mite (HDM) disrupts the epithelial barrier function. The expression of cystatin SN (CST1) is elevated in asthma epithelium. CST1 inhibits the cysteine protease activity.
WebHowever, cystatin SN C-tr and delta 56-60 variants exhibited no inhibitory activity toward papain, while the cystatin SN variants C74S and C84S exhibited slight inhibition at higher concentrations. These results suggested that in the inhibition of papain by cystatin SN, the first disulfide loop is more important than the second.
