General description
Research area: Cell Signaling
Cathepsin D is a soluble endosomal-lysosomal aspartic protease and is synthesized in the rough endoplasmic reticulum as preprocathepsin D. It is encoded by the CTSD gene located in the 11p15.5 region.

Application
Cathepsin D from bovine spleen has been used:
- in in vitro dose-dependent fluorometric activity assays.
- in in vitro myelin oligodendrocyte glycoprotein (MOG) digestion to study the uptake of malondialdehyde (MDA)-modified MOG and its implications in central nervous system autoimmunity.
- for enzymatic digestion of the proteoglycan moiety of the articular cartilage in order to determine its dynamic elastic modulus at two different levels of tissue organization.
- in cathepsin D activity assay.
Biochem/physiol Actions
Cathepsin D is an endosomal-lysosomal aspartic protease implicated in breast cancer metastasis and Alzheimer′s disease. Lysosomal release of cathepsin D has been found to precede cytochrome c release and loss of membrane potential in apoptotic human foreskin fibroblasts. Cathepsin D levels in PC12 cells increase 12 to 24 hours after apoptosis is induced.
