  • FunctionInvolved in the activation cascade of caspases responsible for apoptosis execution. Binding of caspase-9 to Apaf-1 leads to activation of the protease which then cleaves and activates caspase-3. Proteolytically cleaves poly(ADP-ribose) polymerase (PARP).
    Isoform 2 lacks activity is an dominant-negative inhibitor of caspase-9.
  • Tissue specificityUbiquitous, with highest expression in the heart, moderate expression in liver, skeletal muscle, and pancreas. Low levels in all other tissues. Within the heart, specifically expressed in myocytes.
  • Sequence similaritiesBelongs to the peptidase C14A family.
    Contains 1 CARD domain.
  • Developmental stageExpressed at low levels in fetal heart, at moderate levels in neonate heart, and at high levels in adult heart.
  • Post-translational
    Cleavages at Asp-315 by granzyme B and at Asp-330 by caspase-3 generate the two active subunits. Caspase-8 and -10 can also be involved in these processing events.

  • ab52298 at 1/50 dilution staining Caspase 9 in human lung carcinoma by Immunohistochemistry, Paraffin embedded tissue, in the absence or presence of the immunising peptide.
  • ab52298 staining Caspase 9 - Cleaved Asp353 in mouse primary C4-HI cancer cells by Immunocytochemistry/ Immunofluorescence. Cells were fixed in 10% formalin for 20 minutes at room temperature and incubated overnight at 4°C with the primary antibody. The corresponding secondary FITC-conjugated antibody was used at 1/100 dilution and incubated for 1 hour at room temperature. Nuclei were stained red with propidium iodide.
