  • 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.

Thank you for your enquiry and your interest in our products.

I can confirm that ab63488 has not been specifically tested for cross-reactivity with rat, it is only predicted to work in this species based on sequence homology.

Thank you for contacting us. I have checked the antibodies we have in our catalog to Caspase 9, and none of them are likely to show any cross-reactivity with DRONC. The full length proteins are only 24% homologous, so it is unlikely that you would be a...

Merci pour votre réponse.

L'anticorps ab63488 est en effet garanti pour fonctionner en WB et IHC-P. Je suis d'accord avec vous, l'image du blotn'est pas très attractive.
