| Host | Mouse |
| Specificity | Recognizes the full length 32 kDa caspase-3 protein. Highly specific to caspase-3 and shows no cross-reaction with other caspase family members. Caspase-3 is ubiquitously expressed and like other caspases is synthesized as an inactive proenzyme. Upon activation, caspase-3 is cleaved generating two smaller subunits of 17 kDa and 12 kDa. Caspase-3 is one of the most extensively studied enzyme in apoptosis. Activation of caspase-3 occurs in response to a variety of apoptotic inducers. |

| Entrez Gene Number |
|
| Entrez Gene Summary | 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 Alzheimers disease. Alternative splicing of this gene results in two transcript variants that encode the same protein. |

| UniProt Number |
|
| UniProt Summary | 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. |
