Overview
Product name Active Recombinant Human Cathepsin S Protein Catalog No. RP00181 Description Active Recombinant Human Cathepsin S Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Gln17-Ile331) of human Cathepsin S/CTSS (Accession #NP_004070.3) fused with an 8×His tag at the C-terminus. Bio-Activity Measured by its ability to cleave the fluorogenic peptide substrate, Mca-RPKPVE-Nval-WRK(Dnp)-NH2. The specific activity is >1390 pmol/min/μg. Purity > 95% by SDS-PAGE. Endotoxin < 0.1 EU/μg of the protein by LAL method. Formulation Lyophilized from a 0.22 μm filtered solution of 50mM MES, 100mM NaCl, pH6.5.Contact us for customized product form or formulation. Species Human Background
Cathepsin S (CTSS), one of the lysosomal proteinases, has many important physiological functions in the nervous system, especially in process of extracellular matrix degradation and endocellular antigen presentation. Cathepsin S is expressed in the lysosome of antigen presenting cells, primarily dendritic cells, B-cells and macrophages. Cathepsin S is most well known for its critical function in the proteolytic digestion of the invariant chain chaperone molecules, thus controlling antigen presentation to CD4+ T-cells by major histocompatibility complex (MHC) class II molecules or to NK1.1+ T-cells via CD1 molecules. Cathepsin S also appears to participate in direct processing of exogenous antigens for presentation by MHC class II to CD4+ T-cells, or in cross-presentation by MHC class I molecules to CD8+ T-cells. In addition, it has been implicated in the pathogenesis of several diseases such as Alzheimer’s disease and degenerative disorders associated with the cells of the mononuclear phagocytic system.Product information
