| - | '''Caspase''' (CASP) are cysteine-aspartic proteases which function in apoptosis, necrosis and inflammation. Twelve CASP have been identified in human. CASP is synthesized as an inactive pro-CASP with a prodomain which is being cleaved off to render them active. The X-linked inhibitor of apoptosis protein (XIAP) with its baculoviral IAP repeat (BIR) domain is an inhibitor of CASP.<br /> | + | '''Caspase''' (CASP) are cysteine-aspartic proteases (see [[Protease]]) which function in apoptosis, necrosis and inflammation.
