DNA Fragmentation Factor Subunit Alpha, DNA Fragmentation Factor 45 kDa Subunit, DFF-45, Inhibitor of CAD, ICAD, DFFA, DFF1, DFF45, H13
DNA Fragmentation Factor Subunit Alpha (DFFA). DFFA exists as a heterodimer (DFF) with DFFB. DFF is activated once DFFA is cleaved by Caspase-3. The cleaved fragments of DFFA detach from DFFB (the active component of DFF), which in turn triggers DNA fragmentation as well as chromatin condensation during apoptosis. A reduced level of DFFA detected in ovarian endometriosis may be a part of an apoptosis-resistant mechanism enhancing the disease progression.
