CASP3 Human, Sf9

Source: Sf9, Baculovirus cells.Sterile Filtered colorless solution.Caspase 3 Apoptosis-Related Cysteine Peptidase (CASP3) belongs to the cysteine-aspartic acid protease (caspase) family. Sequential activation of caspases plays a key role in the execution-phase of cell apoptosis. Caspases exist as inactive proenzymes which undergo proteolytic processing at conserved aspartic residues to generate 2 subunits, large and small, that dimerize to create the active enzyme. CASP3 protein cleaves and activates caspases 6, 7 and 9, and the protein itself is processed by caspases 8, 9 and 10. CASP3 is the leading caspase involved in the cleavage of amyloid-beta 4A precursor protein, which is linked with neuronal death in Alzheimer's disease. In addition, CASP3 is involved in the cleavage of huntingtin. CASP3 also cleaves and activates sterol regulatory element binding proteins (SREBPs) between the basic helix-loop-helix leucine zipper domain and the membrane attachment domain. CASP3 initiates cell adhesion in sympathetic neurons through RET cleavage.CASP3 Human produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 256 amino acids (29-277 a.a.) and having a molecular mass of 29.4kDa (Migrates at 13.5-18kDa on SDS-PAGE under reducing conditions) . CASP3 is expressed with a 6 amino acid His tag at C-Terminus and purified by proprietary chromatographic techniques.
