Enzyme Information
based on mapping to UniProt P55210
Strict requirement for an Asp residue at position P1 and has a preferred cleavage sequence of Asp-Glu-Val-Asp-|-.
-!- Caspase-7 is an effector/executioner caspase, as are caspase-3 (EC and caspase-6 (EC -!- 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 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, caspase-9 (EC and caspase-10 (EC -!- Removal of the N-terminal prodomain occurs before cleavage in the linker region between the large and small subunits. -!- Belongs to peptidase family C14.
