Cathepsin O
Cathepsin O is an enzyme that in humans is encoded by the CTSO gene.[1][2]
Function
Cathepsin O is a cysteine protease and a member of the cathepsin family and papain superfamily. This proteolytic enzyme is involved in cellular protein degradation and turnover. The recombinant form of this enzyme was shown to degrade synthetic peptides typically used as substrates for cysteine proteinases and its proteolytic activity was abolished by an inhibitor of cyteine proteinase.[2]
