Alternative products:Isoforms differ in the N- and C-termini ,Catalytic activity:Strict requirement for an Asp residue at P1 , with 316-asp being essential for proteolytic activity and has a preferred cleavage sequence of Val-Asp-Val-Ala-Asp-|-. ,Function:Involved in the activation cascade of caspases responsible for apoptosis execution. Might function by either activating some proteins required for cell death or inactivating proteins necessary for cell survival. ,PTM:The mature protease can process its own propeptide , but not that of other caspases. ,similarity:Belongs to the peptidase C14A family. ,similarity:Contains 1 CARD domain. ,subunit:Heterotetramer that consists of two anti-parallel arranged heterodimers , each one formed by a p18 subunit and a p12 subunit. Interacts with LRDD. ,tissue specificity:Expressed at higher levels in the embryonic lung , liver and kidney than in the heart and brain. In adults , higher level expression is seen in the placenta , lung , kidney , and pancreas than in the heart , brain , liver and skeletal muscle. ,
