Research Abstract |
Multiple transcription factors (TFs) regulate transcription by forming TFs-DNA complexes. A cell signaling causes chemical modification of transcription factors, which modulates transcriptional activities. Besides, effect of chemical modification of transcription factors on their activity in the context of TFs-DNA complexes, however, is largely unknown. In this sturdy, we showed that the phosphorylation of a transcription factor Ets1 "differentially" modulates Ets1-containing TFs-DNA complexes. In addition, we clarified the underlying mechanism by which the selective modulation of Ets1-containing TFs-DNA complexes is achieved using NMR analyses of allosteric regulation of Runx1 by CBFβ and crystallographic analyses of multiprotein-DNA complex comprised of Ets1, Runx1 and CBFβ formed on the TCRα gene enhancer.
