Abstract

Cohesins mediate sister chromatid cohesion, which is essential for chromosome segregation and postreplicative DNA repair. In addition, cohesins appear to regulate gene expression and enhancer-promoter interactions. These noncanonical functions remained unexplained because knowledge of cohesin-binding sites and functional interactors in metazoans was lacking. We show that the distribution of cohesins on mammalian chromosome arms is not driven by transcriptional activity, in contrast to S. cerevisiae. Instead, mammalian cohesins occupy a subset of DNase I hypersensitive sites, many of which contain sequence motifs resembling the consensus for CTCF, a DNA-binding protein with enhancer blocking function and boundary-element activity. We find cohesins at most CTCF sites and show that CTCF is required for cohesin localization to these sites. Recruitment by CTCF suggests a rationale for noncanonical cohesin functions and, because CTCF binding is sensitive to DNA methylation, allows cohesin positioning to integrate DNA sequence and epigenetic state.

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?

  • Open chromatin regions are not limited to active enhancers, and also harbour active gene promoters, regulatory elements in a poised chromatin configuration, and some structural regions such as tissue-invariant binding sites for CTCF.

    “However, open chromatin regions are not limited to active enhancers, and also harbour other regions including active gene promoters, regulatory elements in a ‘poised’ chromatin configuration (discussed below), as well as some structural regions such as tissue-invariant binding sites for the architectural protein CCCTC-binding factor (CTCF) [129–132].”
  • CTCF associates with the cohesin complex.

    “A key insight into how CTCF mediates chromosomal looping was the discovery of its association with the cohesin complex [132, 334, 335].”

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.
