Endolysosomal transport of newly-synthesized cathepsin D in a sucrose model of lysosomal storage.


Newly-synthesized soluble lysosomal enzymes are transported from the trans-Golgi network to lysosomes by a mannose 6-phosphate receptor-mediated pathway. Lysosomal storage of indigestible material has been reported to perturb the biosynthesis and the fate of lysosomal hydrolases. In this study, we have focused our attention on the last steps in the… (More)
