      Biological Information
      ImmunogenSynthetic peptide corresponding to amino acids 41-56 of human caspase-9 (Duan et al. 1996; Srinivasula et al. 1996; Nijhawan et al. 1997). Recognizes proform (46 kDa); sequence analysis predicts cross-reactivity with mouse caspase-9 (>90%).

      SpecificityApoptosis is related to many diseases and induced by a family of cell death receptors and their ligands. Cell death signals are transduced by death domain containing adapter molecules and members of the caspase family of proteases. A novel member in the caspase family was recently identified and designated ICE-LAP6, Mch6, and Apaf-3 (Duan et al. 1996; Srinivasula et al. 1996; Nijhawan et al. 1997). Caspase-9 and Apaf-1 bind to each other, which leads to caspase-9 activation (Nijhawan et al. 1997). Caspase-9 is also activated by granzyme B and CPP32 (Duan et al. 1996; Srinivasula et al. 1996). Activated caspase-9 cleaves and activates caspase-3 that is one of the key proteases, being responsible for the proteolytic cleavage of many key proteins in apoptosis (Nijhawan et al. 1997). Caspase-9 plays a central role in cell death induced by a wide variety of apoptosis inducers including TNF-alpha, TRAIL, anti-CD-95, FADD, and TRADD (Pan et al. 1998). Caspase-9 is expressed in a variety of human tissues (Duan et al. 1996; Srinivasula et al. 1996).

      Entrez Gene Number
      Entrez Gene SummaryThis 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 is processed by caspase APAF1; this step is thought to be one of the earliest in the caspase activation cascade. Alternative splicing results in two transcript variants which encode different isoforms.

      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: P55211 # Isoform 2 lacks activity is an dominant-negative inhibitor of caspase-9.
      SIZE: 416 amino acids; 46281 Da
      SUBUNIT: Heterotetramer that consists of two anti-parallel arranged heterodimers, each one formed by a 35 kDa (p35) and a 10 kDa (p10) subunit. Caspase-9 and APAF1 bind to each other via their respective NH2-terminal CED-3 homologous domains in the presence of cytochrome C and ATP. Interacts with the inhibitors BIRC2, BIRC4, BIRC5 and BIRC7.
      TISSUE SPECIFICITY: Ubiquitous, with highest expression in the heart, moderate expression in liver, skeletal muscle, and pancreas. Low levels in all other tissues.
      PTM: 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.
      SIMILARITY: SwissProt: P55211 ## Belongs to the peptidase C14 family. & Contains 1 CARD domain.
