Apoptosis is related to many diseases and induced by a family of cell death receptors and their ligands. Death domain containing adapter molecules and members of the caspase family of proteases transduce cell death signals. These death signals cause the final degradation of chromosomal DNA by activated DNase. A mouse DNase that causes DNA fragmentation was recently identified and designated caspase activated deoxyribonuclease (CAD). The human homologue of mouse CAD was independently identified by three groups and termed CPAN, DFF40, and human CAD, respectively. DFF45/ICAD is the inhibitory protein of DFF40/CAD and forms complex with DFF40/CAD. Upon cleavage of DFF45/ICAD by activated caspase, DFF40/CAD is released and activated and eventually causes the degradation of DNA in the nuclei. Activation of DFF40/CAD, which causes DNA degradation, is the hallmark of apoptotic cell death.
