I bind a motif consisting of Ts and As in the promoter; in prokaryotes I am called [1] and in eukaryotes [2]. I provide a connection between proteins bound to regulatory regions that are far apart: [3] I promote expression by binding an [4] that is located at a large distance from the start of transcription, I am an [5]. One of my functions in eukaryotic transcription initiation is that of a helicase: [6] I am a small molecule that binds a transcription factor and thereby leads to activation or repression of gene expression: [7]
