RNA polymerase II trapped on a molecular treadmill: Structural basis of persistent transcriptional arrest by a minor groove DNA binder

Significance Hairpin pyrrole-imidazole (Py-Im) polyamides can be programmed to bind a broad repertoire of DNA sequences. Py-Im small molecules can be used to target cancer-specific coding regions and block transcription elongation. This transcription blockage by Py-Im cannot be rescued by transcription elongation factors, such as TFIIS. The mechanism by which…
