Application Abreviews Notes
WB 1/5000 - 1/15000. Predicted molecular weight: 43, 23 , 10 kDa.


  • FunctionInvolved in ER-stress induced apoptosis. Cleaves caspase-1 (By similarity). Involved in the activation cascade of caspases responsible for apoptosis execution. Promotes IL-1 beta processing by ICE, so may also have a role in inflammatory responses.
  • Tissue specificityMostly expressed in lung and spleen; weaker in heart and lung; little in liver, skeletal muscle, kidney and testis. Not found in the brain.
  • Sequence similaritiesBelongs to the peptidase C14A family.
    Contains 1 CARD domain.
  • Post-translational
    The two subunits are derived from the precursor sequence by a autocatalytic mechanism.
  • Cellular localizationEndoplasmic reticulum membrane. Mitochondrion.
