描述 Human Caspase 3, recombinant human active 概述 Specificity: Caspase-3 (also known as CPP32, Yama and apopain) is a member of the interleukin-1beta converting enzyme (ICE) family of cysteine proteases. Caspase-3 exists in cells as an inactive 32 kDa proenzyme. During apoptosis procaspase-3 is processed at aspartate residues by self-proteolysis and/or cleavage by upstream caspases, such as caspase-6 (Mch2), caspase-8 (FLICE) granzyme B. The processed form of caspase-3 consists of large (17 kDa) and small (12 kDa) subunits which associate to form the active enzyme. The active caspase-3 has been shown involving in the proteolysis of several important molecules, such as poly (ADP-ribose) polymerase (PARP), the sterol regulatory element binding proteins (SREBPs), focal adhesion kinase (FAK), and others.
The partially purified* active recombinant human caspase-3 protein with full-length His-6 tag was expressed in E. coli. The expressed Caspase-3 spontaneously undergoes autoprocessing to yield the subunits characteristic of the native enzyme. The recombinant caspase-3 preferentially cleaves caspase-3 substrates (e.g., DEVD-AFC or DEVD-pNA). In combination with caspase-3 activity assays, the active recombinant caspase-3 is very useful in the biological screening of caspase inhibitors. The recombinant enzyme can also be used as a positive control in caspase assays or in determining the specificity of caspase substrates.
*10-25% caspase-3 protein by gel analysis, also contains E. Coli proteins. Approximately, 0.8-2 μg total protein / unit of activity. GenBank # U13737.产品信息 演示 Lyophilized. Reconstitute to 1 unit/μL with PBS containing 15% glycerol.
Partially purified recombinant caspase 3 with a full length HIS-6-tag. Approximately 10-20% caspase 3 protein. The remainder is E.Coli proteins. Approximately 0.8-2 mg total protein/U of activity; E.Coli proteins have no reactivity.应用 主要应用 - Activity Assay
应用说明 Western blot: 1-5 μL of stock per lane. Protein is full length caspase 3 with His-Tag. It is autoactivated thus active caspase subunits will be seen
and 17kDa + 12kDa (large and small subunits) can be seen depending upon the antibody. Small subunit is extremely difficult to detect in most westerns. The size of inactive enzime is ~32 kDa.
Activation: Not needed. When expressed in E. coli, caspase-3 spontaneously undergoes autoprocessing to yield the subunits characteristic of the active enzyme.生物信息 纯度 Partially purified recombinant caspase 3 with a full length HIS-6-tag. Approximately 10-20% caspase 3 protein. The remainder is E.Coli proteins. Approximately 0.8-2 mg total protein/U of activity; E.Coli proteins have no reactivity. 品种 Human 特异活性 One unit of the recombinant caspase-3 is the enzyme activity that cleaves 1 nmol of the caspase substrate DEVD-pNA (pNA: pnitroanaline) per hour at 37°C at saturated substrate concentrations.

Entrez基因汇总 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. 基因符号 - Caspase-3 subunit p12].

UniProt编号 - P42574
UniProt汇总 FUNCTION: SwissProt: P42574 # Involved in the activation cascade of caspases responsible for apoptosis execution. At the onset of apoptosis it proteolytically cleaves poly(ADP-ribose) polymerase (PARP) at a '216-Asp- -Gly-217' bond. Cleaves and activates sterol regulatory element binding proteins (SREBPs) between the basic helix-loop- helix leucine zipper domain and the membrane attachment domain. Cleaves and activates caspase-6, -7 and -9. Involved in the cleavage of huntingtin.
SIZE: 277 amino acids; 31608 Da
SUBUNIT: Heterotetramer that consists of two anti-parallel arranged heterodimers, each one formed by a 17 kDa (p17) and a 12 kDa (p12) subunit.
SUBCELLULAR LOCATION: Cytoplasm.
TISSUE SPECIFICITY: Highly expressed in lung, spleen, heart, liver and kidney. Moderate levels in brain and skeletal muscle, and low in testis. Also found in many cell lines, highest expression in cells of the immune system.
PTM: Cleavage by granzyme B, caspase-6, caspase-8 and caspase-10 generates the two active subunits. Additional processing of the propeptides is likely due to the autocatalytic activity of the activated protease. Active heterodimers between the small subunit of caspase-7 protease and the large subunit of caspase-3 also occur and vice versa.
SIMILARITY: SwissProt: P42574 ## Belongs to the peptidase C14 family.产品使用声明 使用声明 - Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals.
