Structural Insight into the DNA Binding Function of Transcription Factor ERF.

ABSTRACT: ETS family transcription factors control development of different cell types in humans, whereas deregulation of these proteins leads to severe developmental syndromes and cancers. One of a few members of the ETS family that are known to act solely as repressors, ERF, is required for normal osteogenesis and hematopoiesis. Another important function of ERF is acting as a tumor suppressor by antagonizing oncogenic fusions involving other ETS family factors. The structure of ERF and the DNA binding properties specific to this protein have not been elucidated. In this study, we determined two crystal structures of the complexes of the DNA binding domain of ERF with DNA. In one, ERF is in a distinct dimeric form, with Cys72 in a reduced state. In the other, two dimers of ERF are assembled into a
