ジャーナル: Sci Adv / 年: 2025 タイトル: Structural insights into promoter-proximal pausing of RNA polymerase II at +1 nucleosome. 著者: Masahiro Naganuma / Tomoya Kujirai / Haruhiko Ehara / Tamami Uejima / Tomoko Ito / Mie Goto / Mari Aoki / Masami Henmi / Sayako Miyamoto-Kohno / Mikako Shirouzu / Hitoshi Kurumizaka / Shun-Ichi Sekine / 要旨: The metazoan transcription elongation complex (EC) of RNA polymerase II (RNAPII) generally stalls between the transcription start site and the first (+1) nucleosome. This promoter-proximal pausing ...The metazoan transcription elongation complex (EC) of RNA polymerase II (RNAPII) generally stalls between the transcription start site and the first (+1) nucleosome. This promoter-proximal pausing involves negative elongation factor (NELF), 5,6-dichloro-1-β-d-ribobenzimidazole sensitivity-inducing factor (DSIF), and transcription elongation factor IIS (TFIIS) and is critical for subsequent productive transcription elongation. However, the detailed pausing mechanism and the involvement of the +1 nucleosome remain enigmatic. Here, we report cryo-electron microscopy structures of ECs stalled on nucleosomal DNA. In the absence of TFIIS, the EC is backtracked/arrested due to conflicts between NELF and the nucleosome. We identified two alternative binding modes of NELF, one of which reveals a critical contact with the downstream DNA through the conserved NELF-E basic helix. Upon binding with TFIIS, the EC progressed to the nucleosome to establish a paused EC with a partially unwrapped nucleosome. This paused EC strongly restricts EC progression further downstream. These structures illuminate the mechanism of RNAPII pausing/stalling at the +1 nucleosome.
