Comment(s)
  • Caspase-7 is an effector/executioner caspase, as are caspase-3 (EC 3.4.22.56) and caspase-6 (EC 3.4.22.59).
  • These caspases are responsible for the proteolysis of the majority of cellular polypeptides, [e.g. poly(ADP-ribose) polymerase (PARP)], which lead to the apoptotic phenotype.
  • Although a hydrophobic residue at P5 of caspase-2 (EC 3.4.22.55) and caspase-3 leads to more efficient hydrolysis, the amino-acid residue at this location in caspase-7 has no effect.
  • Caspase-7 is activated by the initiator caspases [caspase-8 (EC 3.4.22.61), caspase-9 (EC 3.4.22.62) and caspase-10 (EC 3.4.22.63)].
  • Removal of the N-terminal prodomain occurs before cleavage in the linker region between the large and small subunits.
  • Belongs to peptidase family C14.
