Outline of Final Research Achievements |
Signal transduction transfers cellular environmental information to nucleus via chemical modifications of proteins and finally modulates transcription profile of the cell. To reveal the molecular mechanism of conversion of the information from chemical modification to transcriptional modulation, we employed static and dynamic structural analyses of higher-ordered transcription factors(TF)-DNA complexes. We found that phosphorylation of the intrinsically disordered region of the transcription factor Ets1 induces a non-DNA-binding conformer of Ets1 itself. On the tcrα enhancer, the partner TF Runx1 selects the specific Ets1 conformer that is refractory to effect of phosphorylation, resisting the inhibitory effect of phosphorylation of Ets1 and specifically keeping the tcrα gene transcription active, while many of other Ets1-target genes turn off. This transcription switch may enable fine regulation responding to cellular environments including development and proliferation signals.
