Abstract

Recent studies on enzymes and reader proteins for histone crotonylation support a function of histone crotonylation in transcription. However, the enzyme(s) responsible for histone decrotonylation (HDCR) remains poorly defined. Moreover, it remains to be determined if histone crotonylation is physiologically significant and functionally distinct from or redundant to histone acetylation. Here we present evidence that class I histone deacetylases (HDACs) rather than sirtuin family deacetylases (SIRTs) are the major histone decrotonylases, and that histone crotonylation is as dynamic as histone acetylation in mammalian cells. Notably, we have generated novel HDAC1 and HDAC3 mutants with impaired HDAC but intact HDCR activity. Using these mutants we demonstrate that selective HDCR in mammalian cells correlates with a broad transcriptional repression and diminished promoter association of crotonylation but not acetylation reader proteins. Furthermore, we show that histone crotonylation is enriched in and required for self-renewal of mouse embryonic stem cells.

  • HDACs regulate several other lysine acylations-including depropionylation, demyristoylation, and desuccinylation-which contribute to transcriptional control, metabolic regulation, and cellular stress responses.

    “In addition to removing acetyl groups, HDACs regulate several other lysine acylations—including depropionylation, demyristoylation, and desuccinylation—which contribute to transcriptional control, metabolic regulation, and cellular stress responses (Wei et al., 2017).”

    From Histone modifications and depression: epigenetic mechanisms, therapeutic targets, and translational outlook (2026) · cites this paper as Wei et al., 2017

    The Introduction (page not provided) reports depropionylase activity in several SIRTs and desuccinylase activity in SIRT5, and the paper links histone decrotonylation to transcriptional regulation. It does not substantiate demyristoylation or cellular stress responses, and its findings on transcription concern crotonylation rather than all the acylations listed in the claim. (LLM, conf=0.86)

  • Histone crotonylation is catalyzed by HATs, which add a crotonyl group from crotonyl-CoA to histone amino acid residues, while HDACs 1/2/3 and sirtuin 1/2/3 act as decrotonylases.

    “histone crotonylation is catalyzed by HATs, which add a crotonyl group from crotonyl-coenzyme A (CoA) to amino acid residues of histones,111 while HDACs 1/2/3 and sirtuin 1/2/3, act as decrotonylases.180–182”

    From Epigenetic regulation in major depression and other stress-related disorders: molecular mechanisms, clinical relevance and therapeutic potential (2023) · cites this paper as [182]

    The Results section ('Class I HDACs possess HDCR activity'; page unavailable) supports decrotonylase activity for HDAC1/2/3 and SIRT1. The Discussion reports prior in-vitro activity for SIRT2 and SIRT3, but says this study detected no significant activity for either in cells. Thus, the unqualified inclusion of SIRT2/3 is not fully supported. The HAT clause carries a different citation and is not assessed here. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • HDAC1/2 have been implicated in the regulation of histone crotonylation levels in cells.

    “Recently, HDAC1/2 have been implicated in the regulation of histone crotonylation levels in cells21,22.”
  • siRNA knockdown of HDAC1/2 or HDAC inhibitor treatment causes increased levels of histone crotonylation.

    “siRNA knockdown of HDAC1/221 or treatment with HDAC inhibitors22 caused increased levels of histone crotonylation; although counterintuitively, the average level of H3K18cr at transcriptional start sites (TSS) was reduced following HDAC inhibitor treatment22.”
  • Total decrotonylase activity correlates with the total amount of HDAC1/2.

    “This difference in activity suggests that HDAC2 acts as a histone decrotonylase, consistent with data from Wei et al.21 and that total decrotonylase activity (similar to deacetylase) correlates with the total amount of HDAC1/2.”

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.
