The enzyme responsible for apoptotic DNA fragmentation is the Caspase-Activated DNase (CAD) . CAD is normally inhibited by another protein, the Inhibitor of Caspase Activated DNase (ICAD) . During apoptosis, the apoptotic effector caspase, caspase 3, cleaves ICAD and thus causes CAD to become activated.n apoptotic DNA fragmentation, the DNA is cleaved in the internucleosomal linker region, which is the part of the DNA not wrapped around the histones. CAD cleaves DNA at internucleosomal linker sites between nucleosomes, protein-containing structures that occur in chromatin at ~180-bp intervals.
