Apoptosis
Research on apoptosis published by K. Omata et al
September 2nd, 2008
"DNA fragmentation factor is a heterodimer complex of the nuclease CAD and its specific inhibitor ICAD, which can be activated during apoptosis to induce DNA fragmentation. Although ICAD expression levels have been quantified in a variety of human cancer cells, the mechanism of ICAD gene regulation remains unknown," researchers in Toyama, Japan report. "In this study, we identified a 106-bp TATA-less region upstream of the transcription start site as a basal promoter of the human ICAD gene. An E-Box motif, which binds transcription factors of the basic helix-loop-helix/leucine zipper family, is responsible for transcriptional activity, as demonstrated using mutated...
