Transcriptional interference by RNA polymerase pausing and dislodgement of transcription factors

Transcription. 2011 Jan-Feb;2(1):9-14. doi: 10.4161/trns.2.1.13511.

Abstract

Transcriptional interference is the in cis suppression of one transcriptional process by another. Mathematical modeling shows that promoter occlusion by elongating RNA polymerases cannot produce strong interference. Interference may instead be generated by (1) dislodgement of slow-to-assemble pre-initiation complexes and transcription factors and (2) prolonged occlusion by paused RNA polymerases.

Keywords: RNAP pausing; TRCF; dislodgement; gene regulation; tandem promoters; transcription factor; transcriptional interference.
