Abstract

Maintaining Repression: The Polycomb Repressive Complex 2 (PRC2) plays a critical role in gene silencing in metazoans, methylating histone H3 on lysine 27 (H3K27) to generate a repressive chromatin mark. The catalytic subunit E(z)/Ezh2 requires the presence of two other subunits—ESC/EED and Su(z)12—for enzyme activity. Yuan et al. (p. 971 ; see the Perspective by Pirrotta ) show that both a fragment of the histone H3 N-terminal tail, and histone H1 stimulated PRC2 enzyme activity on poor, low-density chromatin substrates, indicating that that PRC2 is regulated by the density and compaction states of chromatin. The histone H3 fragment binds to the Su(z)12 subunit of PRC2 to stimulate E(z)/Ezh2. Local chromatin compaction preceded establishment of histone H3K27 methylation indicating how PRC2 might maintain the repressed state.

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.
