After synthesis, CTSB is cleaved by a signal peptidase inside the ER lumen to become proCTSB (46 kDa) . This proCTSB is glycosylated with high levels of mannose within the ER before being transported via ER-derived transport vesicles to the Golgi apparatus. riehl spedition bremenWebbCathepsin B is a cysteine protease, found in the lysosome of normal cells and tissues.
