Summary: Enables sequence-specific DNA binding activity. Involved in regulation of transcription by RNA polymerase II; termination of RNA polymerase II transcription; and transcriptional start site selection at RNA polymerase II promoter. Located in nucleoplasm. Orthologous to human DMTF1 (cyclin D binding myb like transcription factor 1) and TTF1 (transcription termination factor 1).

Both the binding and dissociation rates of Reb1 and Cbf1 are significantly slower at the nucleosomal sites relative to those for naked DNA, demonstrating that the high affinities are achieved by increasing the dwell time on nucleosomes in order to compensate for reduced binding.

It was found that ABF1, FKH2, and REB1 overexpression decreased the growth of strains in a prion-dependent manner and, thus, might influence [PSI;(+)] prion toxicity.

Reb1p indeed binds to the TFC6 promoter, and is important for proper transcription start site selection and protein expression. Interestingly, loss of Reb1p association at this site has a similar effect on the adjacent divergently transcribed ESC2 promoter, resulting in a significant increase of 5'-extended ESC2 transcripts and reduction of Esc2 protein levels.

Data show that the transcriptional activator Reb1p bound to DNA is a roadblock for RNAPII, which pauses and is ubiquitinated, thus triggering termination
