- Apoptosis related cysteine peptidase
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.
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.
