Figure 1B and 1C show that the cysteine protease inhibitor inhibited human cathepsin L, human cathepsin B, and papain enzymes. All of these enzymes are part of the C1 family of cysteine proteinases, therefore showing that the cysteine protease inhibitor inhibits protease, or peptidase, activity.

Figure two shows that the cysteine protease inhibitor, originally located in the cytoplasm, localizes to the lysosome during cyst formation.
