Modulation of transcription factor Ets-1 DNA binding: DNA-induced unfolding of an alpha helix

JM Petersen, JJ Skalicky, LW Donaldson, LP McIntosh, T Alber, and BJ Graves

Department of Oncological Sciences, University of Utah School of Medicine, Salt Lake City 84132, USA.

Conformational changes, including local protein folding, play important roles in protein-DNA interactions. Here, studies of the transcription factor Ets-1 provided evidence that local protein unfolding also can accompany DNA binding. Circular dichroism and partial proteolysis showed that the secondary structure of the Ets-1 DNA-binding domain is unchanged in the presence of DNA. In contrast, DNA allosterically induced the unfolding of an alpha helix that lies within a flanking region involved in the negative regulation of DNA binding. These findings suggest a structural basis for the intramolecular inhibition of DNA binding and a mechanism for the cooperative partnerships that are common features of many eukaryotic transcription factors.
