Abstract

The packaging of the eukaryotic genome into chromatin is likely to have a profound influence on transcription from the underlying genes. We have previously shown that the disassembly of promoter nucleosomes is obligatory for activation of the yeast PHO5 and PHO8 genes. Here, we show that the PHO5 promoter nucleosomes are reassembled concomitant with transcriptional repression and displacement of the TATA binding protein and RNA polymerase II (RNA Pol II). We identify the histone H3-H4 chaperone Spt6 as the factor that mediates nucleosome reassembly onto the PHO5, PHO8, ADH2, ADY2, and SUC2 promoters during transcriptional repression. Furthermore, promoter nucleosome reassembly is essential for transcriptional repression. In the absence of Spt6-mediated nucleosome reassembly, the activators Pho4 and Pho2 are displaced from the PHO5 promoter in repressing conditions, yet transcription is sustained. As such, these studies demonstrate that activators are not required for transcription in the absence of competing chromatin reassembly.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Spt6 physically interacts with histone H3 and can facilitate nucleosome reassembly.

    “Another factor reported to increase RNA Pol II speed is the transcription elongation factor Spt6, which physically interacts with histone H3 (Bortvin & Winston, 1996; Winkler et al, 2000) and can facilitate nucleosome reassembly (Adkins & Tyler, 2006).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
