Modulation of ATP-Dependent Chromatin-Remodeling Complexes by Inositol Polyphosphates

Abstract

Eukaryotes use adenosine triphosphate (ATP)–dependent chromatin-remodeling complexes to regulate gene expression. Here, we show that inositol polyphosphates can modulate the activities of several chromatin-remodeling complexes in vitro. Inositol hexakisphosphate (IP 6 ) inhibits nucleosome mobilization by NURF, ISW2, and INO80 complexes. In contrast, nucleosome mobilization by the yeast SWI/SNF complex is stimulated by inositol tetrakisphosphate (IP 4 ) and inositol pentakisphosphate (IP 5 ). We demonstrate that mutations in genes encoding inositol polyphosphate kinases that produce IP 4 , IP 5 , and IP 6 impair transcription in vivo. These results provide a link between inositol polyphosphates, chromatin remodeling, and gene expression.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, 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?

  • Several further studies have supported the importance of Arg82 kinase activity in transcriptional regulation and chromatin remodelling, together suggesting that Ins(1,4,5,6)P4 has an important regulatory role in yeast.

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.
