  • FunctionThiol protease that cleaves IL-1 beta between an Asp and an Ala, releasing the mature cytokine which is involved in a variety of inflammatory processes. Important for defense against pathogens. Cleaves and activates sterol regulatory element binding proteins (SREBPs). Can also promote apoptosis.
  • Tissue specificityExpressed in larger amounts in spleen and lung. Detected in liver, heart, small intestine, colon, thymus, prostate, skeletal muscle, peripheral blood leukocytes, kidney and testis. No expression 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 an autocatalytic mechanism.

Thank you for contacting Abcam.
Based on the information from UniPort (SwissProt: P29466), there are a number of isoforms of Caspase-1, one of which is about 30kDa. I am not sure which isoforms is expressed in 293 cell extracts.
Although we d...
