  • 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.

No, to our knowledge, this anitbody has only been tested in WB.

This antibody was made with a peptide located at amino acids 41-56 of human caspase-9. The peptide is located in the cleaved and activated fragment (35 or 37 kDa). Therefore, it should recognize the precursor and activated form although we have not t...
