产品详细信息Description: Caspases are present in all cells, recruitment of these proteases to oligomerized receptors leads to activation accompanied by autoproteolytic cleavage. Active caspases can proteolyze additional caspases generating a caspase cascade that cleaves proteins critical for cell survival. The final outcome of this signaling pathway is a form of controlled cell death termed apoptosis. The subgroup of caspases involved in apoptosis is called initiators or effectors. Caspase-3 cleaves substrate at the carboxyl terminus of aspartate residues. Active caspase-3 has two active sites and consists of two identical large (~ 20 kDa) and two identical small (~ 10 kDa) subunits that are derived from two precursor caspase-3 polypeptides. Caspase-3 is proteolytically activated by other caspases.Both subunits contribute to substrate binding and catalysis. The active site cysteine that covalently binds the substrate is located near the C-terminus of the large subunit. Active caspase-3 has two-fold symmetry, two active site pockets each residing on an opposite side. Caspase-3, together with caspases 8 and 9, is situated at pivotal junctions in apoptotic pathways. Caspase-3 appears to amplify caspase 8 and 9 initiation signals into complete commitment to apoptotic disassembly.Applications Tested: ELISA, Western Blotting.靶标信息This gene encodes a protein which is a member of the cysteine-aspartic acid protease (caspase) family. Sequential activation of caspases plays a central role in the execution-phase of cell apoptosis. Caspases exist as inactive proenzymes which undergo proteolytic processing at conserved aspartic residues to produce two subunits, large and small, that dimerize to form the active enzyme. This protein cleaves and activates caspases 6, 7 and 9, and the protein itself is processed by caspases 8, 9 and 10. It is the predominant caspase involved in the cleavage of amyloid-beta 4A precursor protein, which is associated with neuronal death in Alzheimer's disease. Alternative splicing of this gene results in two transcript variants that encode the same protein.
