Apoptosis is a cell death process that removes toxic and/or useless cells during mammalian development. The apoptotic process is accompanied by shrinkage and fragmentation of the cells and nuclei and degradation of the chromosomal DNA into nucleosomal units. DNA fragmentation factor (DFF) is a heterodimeric protein of 40-kD (DFFB) and 45-kD (DFFA) subunits. DFFA is the substrate for caspase-3 and triggers DNA fragmentation during apoptosis. DFF becomes activated when DFFA is cleaved by caspase-3. The cleaved fragments of DFFA dissociate from DFFB, the active component of DFF. DFFB has been found to trigger both DNA fragmentation and chromatin condensation during apoptosis. Two alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
[中文简述(自动翻译):]  细胞凋亡是细胞死亡的过程,哺乳动物发育过程中删除的毒性和/或无用的细胞。细胞凋亡过程伴随着细胞和细胞核和染色体DNA成核小体单位的降解的收??缩和碎片。 DNA片段化因子(DFF)为40-KD(DFFB)和45 kD的(DFFA)亚基的异源二聚体蛋白质。 DFFA为胱天蛋白酶3在基片和凋亡过程中触发DNA片段。当DFFA由caspase-3的裂解DFF被激活。 DFFA的切割片段从DFFB,DFF的活性成分分解。 DFFB已经发现细胞凋亡过程中,同时触发DNA片段化和染色质浓缩。已经发现了这个基因编码两种不同亚型选择性剪接转录变异体。 [由RefSeq的,2008年7月提供]
