General description

Cathepsins are proteases that normally localized in lysosomes of almost all mammalian cells, but under certain conditions they can be secreted from the cell. Cathepsins are classified based on their functions and presence of active site such as cathepsin B, D, K, V, F etc.
Monoclonal Anti-Cathepsin K (mouse IgG2b isotype) is derived from the hybridoma CK124-1H6 produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with recombinant human cathepsin K.

Specificity

The antibody does not cross react with the closely related lysosomal cysteine proteases cathepsins L, B, H, S, V and W.

Immunogen

recombinant human cathepsin K. The antibody epitope resides within the peptide sequence RGYREIPEGNEKAL that corresponds to amino acids 222-235.

Application

Monoclonal Anti-Cathepsin K antibody produced in mouse has been used in western blotting and enzyme linked immunosorbent assay (ELISA).

Biochem/physiol Actions

Cathepsin is involved in various functions such as intracellular degradation of exogenous and endogenous proteins, activation of enzyme precursors, and tumor invasion and metastasis. Among all the types, cathepsins K (Ctsk) is highly expressed in osteoclasts that plays a crucial role in bone remodeling and resorption. Cathepsin K protein was found in primary breast carcinoma and prostate cancer where it performs in the invasive process of prostate cancers, thyroid carcinoma, lung adenocarcinoma and breast carcinoma. Its deficency causes pycnodysostosis, a rare bone dysplasia with an osteopetrotic-like phenotype.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.
