功能Involved 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.
组织特异性Ubiquitous, 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.
序列相似性Belongs to the peptidase C14A family. Contains 1 CARD domain.
发展阶段Expressed at low levels in fetal heart, at moderate levels in neonate heart, and at high levels in adult heart.
翻译后修饰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.

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.

Immunohistochemical analysis of frozen retina tissue, taken from wild-type (top) or S334ter rhodopsin transgenic rats (bottom).
Caspase 9 - Cleaved Asp353 was stained using ab52298 at 1/100 dilution. An AlexaFluor® 488-conjugated IgG was used as the secondary antibody.
