常规信息

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 effector caspases caspase-3 (CASP3) or caspase-7 (CASP7). Promotes DNA damage-induced apoptosis in a ABL1/c-Abl-dependent manner. Proteolytically cleaves poly(ADP-ribose) polymerase (PARP). Cleaves BIRC6 following inhibition of BIRC6-caspase binding by DIABLO/SMAC (PubMed : 36758105, PubMed : 36758106).. Isoform 2. Lacks activity is an dominant-negative inhibitor of caspase-9.

序列相似性

Belongs to the peptidase C14A family.

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.. Phosphorylated at Thr-125 by MAPK1/ERK2. Phosphorylation at Thr-125 is sufficient to block caspase-9 processing and subsequent caspase-3 activation. Phosphorylation on Tyr-153 by ABL1/c-Abl; occurs in the response of cells to DNA damage.. (Microbial infection) ADP-riboxanation by C.violaceum CopC blocks CASP9 processing, preventing CASP9 activation and ability to mediate intrinsic apoptosis.. Ubiquitinated by BIRC6; this activity is inhibited by DIABLO/SMAC.
