Promiscuous RNA binding by Polycomb repressive complex 2
Open accessAbstract
Polycomb repressive complex 2 (PRC2) is a histone methyltransferase required for epigenetic silencing during development and cancer. Long noncoding RNAs (lncRNAs) recruit PRC2 to chromatin, but the general role of RNA in maintaining repressed chromatin is unknown. Here we measure the binding constants of human PRC2 to various RNAs and find comparable affinity for human lncRNAs targeted by PRC2 as for irrelevant transcripts from ciliates and bacteria. PRC2 binding is size dependent, with lower affinity for shorter RNAs. In vivo, PRC2 predominantly occupies repressed genes; PRC2 is also associated with active genes, but most of those are not regulated by PRC2. These findings support a model in which PRC2's promiscuous binding to RNA transcripts allows it to scan for target genes that have escaped repression, thus leading to maintenance of the repressed state. Such RNAs may also provide a decoy for PRC2.

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.
