Caspase-9
| View/Edit Human | View/Edit Mouse |
Caspase-9 is an initiator caspase,[3] encoded by the CASP9 gene. CASP9 orthologs [4] have been identified in all mammals for which complete genome data are available. Unique orthologs are also present in lizards, lissamphibians, and teleosts.
The aspartic acid specific protease caspase-9 has been linked to the mitochondrial death pathway. It is activated during programmed cell death (apoptosis). Induction of stress signaling pathways JNK/SAPK causes release of cytochrome c from mitochondria and activation of apaf-1 (apoptosome), which in turn cleaves the pro-enzyme of caspase-9 into the active form.
Once initiated caspase-9 goes on to cleave procaspase-3 & procaspase-7, which cleave several cellular targets, including poly ADP ribose polymerase.
Structure
Caspase-9 precursor procaspase-9 is present as an inactive monomer before it undergoes a conformational change to a dimer and associates with the apf-1 and cytochrome c complex to form an apoptosome.[5]
Interactions
Caspase-9 has been shown to interact with:
