Rabbit anti- Caspase-9 Polyclonal Antibody

Uniprot Id

P55211

Target Species

Human

Target Name

CASP9

Target Full Name

Caspase-9

Target Function

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. Promotes DNA damage-induced apoptosis in a ABL1/c-Abl-dependent manner. Proteolytically cleaves poly(ADP-ribose) polymerase (PARP).; Isoform 2 lacks activity is an dominant-negative inhibitor of caspase-9.

Target Protein Families

Peptidase C14A family

Target Tissue Specificity

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.

Target Synonyms

APAF-3; Apoptotic protease Mch-6; Apoptotic protease-activating factor 3; CASP-9; CASP9; CASP9_HUMAN; Caspase 9; Caspase-9 subunit p10; ICE-LAP6; ICE-like apoptotic protease 6

Target Background

This gene encodes a member of the cysteine-aspartic acid protease (caspase) family. Sequential activation of caspases plays a central role in the execution-phase of cell apoptosis. Caspases exist as inactive proenzymes which undergo proteolytic processing at conserved aspartic residues to produce two subunits, large and small, that dimerize to form the active enzyme. This protein can undergo autoproteolytic processing and activation by the apoptosome, a protein complex of cytochrome c and the apoptotic peptidase activating factor 1; this step is thought to be one of the earliest in the caspase activation cascade. This protein is thought to play a central role in apoptosis and to be a tumor suppressor. Alternative splicing results in multiple transcript variants.
