Cathepsin W Proteins and Enzymes

The protein encoded by the Cathepsin W gene, a member of the peptidase C1 family, is a cysteine proteinase that may have aspecific function in the mechanism or regulation of T-cell cytolytic activity. The encoded protein is found associatedwith the membrane inside the endoplasmic reticulum of natural killer and cytotoxic T-cells. Expression of this gene isup-regulated by interleukin-2.
