Caspase 4


Caspase 4 is an enzyme that proteolytically cleaves other proteins at an aspartic acid residue, and belongs to a family of cysteine proteases called caspases. The function of caspase 4 is not fully known, but it is believed to be an inflammatory caspase, along with caspase 1, caspase 5, with a role in the immune system.
The anti-inflammatory drug indoprofen is an inhibitor of the activity of the caspase-4 enzyme.
