Caspase-2 (also know as Ich-1, Nedd-2) is a member of the caspase-family of cysteine proteases. Similar to other caspases, caspase-2 also exists in cells as an inactive proenzyme. During apoptosis pro-caspase-2 is processed at aspartate residues by self-proteolysis and/or cleavage by upstream caspases. The processed active caspase-2 is a heterotetramer consisting of two large (19 kDa) and two small (12 kDa) subunits.The recombinant active human caspase-2 was expressed in E. coli. The active caspase-2 preferentially cleaves caspase-2 substrates (e.g., VDVAD-AFC or VDVAD-pNA) and is routinely tested at BioVision for its ability to enzymatically cleave these two substrates Ac-VDVAD-pNA (Cat. #1072-200) or Ac-VDVAD-AFC (1071-200).
