      DescriptionCaspase 9 Colorimetric Activity Assay Kit, LEHD
      OverviewActivation of ICE-family proteases/caspases initiates apoptosis in mammalian cells. Chemicon's Caspase-9 Colorimetric Activity Assay Kits provide a simple and convenient means for assaying the activity of caspases that recognize the LEHD. The assay is based on spectophotometric detection of the chromophore p-nitroaniline (pNA) after cleavage from the labeled substrate LEHD-pNA. The free pNA can be quantified using a spectrophotometer or a microtiter plate reader at 405 nm. Comparison of the absorbance of pNA from an apoptotic sample with an uninduced control allows determination of the fold increase in caspase-9 activity.

      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.
