Cathepsin B Antibody [FITC] Summary

• Immunogen: Native, from placenta
• Specificity: This antibody detects cathepsin B, a lysosomal cysteine protease which functions as both a endopeptidase and a carboxypeptidase. Together with cathepsins D and L, cathepsin B is one of the most abundant proteases in the lysosome, and participates in intracellular protein degradation.

Background

Cathepsin B is a normal lysosomal proteinase that is expressed in all cells. It is a cysteine endoproteinase structurally and functionally related to the papain family of proteases. Cathepsin B is synthesized as an inactive 43 kDa pro enzyme which, by removal of a 62 amino acid propeptide, is activated to the single chain form of 31 kDa or the two chain form (25 and 5 kDa subunits). Matured Cathepsin B is normally localized in the lysosomes where it functions in protein turnover. Cathepsin B is also shown capable of degrading extracellular matrix proteins at acidic and neutral pH. Endogenous inhibitors of cysteine proteases, the cystatins and stefins, may play a major role in regulating their activity. In tumor cells and in cells exposed to mitogens, cathepsin B displays altered cellular trafficking resulting in the secretion of the 43 kDa precursor. Elevated levels of Cathepsin B correlate with malignancy suggesting that this enzyme may be a useful prognostic marker for several types of human cancers. Cathepsin B has also been implicated in the pathogenesis of rhematoid arthritis, muscular dystrophy and tumor metastasis.
