Abstract

Regulation of enhancer activity is important for controlling gene expression programs. Here, we report that a biochemical complex containing a potential chromatin reader, RACK7, and the histone lysine 4 tri-methyl (H3K4me3)-specific demethylase KDM5C occupies many active enhancers, including almost all super-enhancers. Loss of RACK7 or KDM5C results in overactivation of enhancers, characterized by the deposition of H3K4me3 and H3K27Ac, together with increased transcription of eRNAs and nearby genes. Furthermore, loss of RACK7 or KDM5C leads to de-repression of S100A oncogenes and various cancer-related phenotypes. Our findings reveal a RACK7/KDM5C-regulated, dynamic interchange between histone H3K4me1 and H3K4me3 at active enhancers, representing an additional layer of regulation of enhancer activity. We propose that RACK7/KDM5C functions as an enhancer "brake" to ensure appropriate enhancer activity, which, when compromised, could contribute to tumorigenesis.

  • ZMYND8 functions as a reader to recognize the acetylation of histone 3 at K14.

    “ZMYND8 (also named PRKCBP1 or RACK7) functions as a reader to recognize the acetylation of histone 3 at K14.”

    From HBO1 functions as an epigenetic barrier to hepatocyte plasticity and reprogramming during liver injury (2025) · cites this paper as [37]

    The Results section ('RACK7 primarily binds active enhancers'; page unavailable) identifies RACK7 as ZMYND8 and reports its binding at active enhancers. It describes the related protein BS69/ZMYND11—not RACK7—as a histone-mark reader. Searches for H3K14, lysine-14 acetylation, and acetylated-histone recognition found no passage saying that ZMYND8 reads H3K14 acetylation. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • ZMYND8 occupies many active enhancers and recruits KDM5C to super enhancer regions to maintain low H3K4me3 levels resulting in repression of enhancer activity.

    “ZMYND8 occupies many active enhancers and recruits KDM5C to super enhancer regions to maintain low H3K4me3 levels resulting in the repression of enhancer activity 35–37.”

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.
