Abstract

For gene enhancers, less is more: Weak enhancer sequences provide just the right amount of gene activity. Farley et al. systematically examined millions of synthetic variants of the Otx enhancer, a motif needed for gene expression in the nervous system of the sea squirt Ciona. Proper gene activity resulted when there were imperfect matches to the motif showing strongest enhancer binding and gene activation. When “optimal” motifs were incorporated, ectopic expression ensued, with aberrant gene activation outside the nervous system. Science , this issue p. 325

  • Flexible enhancer grammar ensures robust gene expression control through suboptimal transcription factor binding motifs, which reinforce the requirement for transcription factor cooperativity and create opportunities for fine-tuning enhancer activity levels.

    “Another means by which flexible enhancer grammar ensures robust gene expression control is through “suboptimal” TF binding motifs, which reinforce the requirement for TF cooperativity and create opportunities for fine-tuning enhancer activity levels [125–128].”

  • Strengthening transcription factor binding sites at developmental enhancers results in aberrant gene expression patterns.

    “Consistent with this, “strengthening” TF binding sites at developmental enhancers results in aberrant gene expression patterns [125].”

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.
