Target
-
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
modificationsCleavages 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. - Information by UniProt

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. -
