Descripción

General description

Anti-Cathepsin D antibody, Mouse monoclonal (mouse IgG2a isotype) is derived from the CTD-19 hybridoma, produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mouse immunized with cathepsin D purified from human liver. Cathepsin D (CatD or CTSD) is synthesized in the rough endoplasmic reticulum as pre-proprotein. After removal of signal peptide, the pro-CatD is targeted to endosomes to form an active, ~48 kDa, single-chain intermediate then to the lysosomes to form the fully active mature protease, composed of a ~30 kDa heavy chain and a ~14 kDa light chain.

Immunogen

• immunofluorescence

Biochem/physiol Actions

CatD plays numerous physiological functions in the cells including metabolic degradation of intracellular proteins and the activation of enzymatic precursors. In the central nervous system, CatD is particularly important for the control of neuronal homeostasis, cell migration and interneuron communication. CatD-mediated proteolysis mediates the degradation of unfolded/oxidized protein aggregates in lysosome. The level of CatD synthesized by the cells is increased in response to mitogenic signals from estrogen, epidermal growth factor (EGF), fibroblast growth factor (FGF), and insulin like growth factor-I (IGF- I). The ability of tumor cells to invade the extracellular matrix has been attributed to cathepsins released by tumor cells or associated with its plasma membrane.
