Abstract

Nε-lysine acetylation was discovered more than half a century ago as a post-translational modification of histones and has been extensively studied in the context of transcription regulation. In the past decade, proteomic analyses have revealed that non-histone proteins are frequently acetylated and constitute a major portion of the acetylome in mammalian cells. Indeed, non-histone protein acetylation is involved in key cellular processes relevant to physiology and disease, such as gene transcription, DNA damage repair, cell division, signal transduction, protein folding, autophagy and metabolism. Acetylation affects protein functions through diverse mechanisms, including by regulating protein stability, enzymatic activity, subcellular localization and crosstalk with other post-translational modifications and by controlling protein-protein and protein-DNA interactions. In this Review, we discuss recent progress in our understanding of the scope, functional diversity and mechanisms of non-histone protein acetylation.

  • Approved KDAC inhibitors are largely non-selective because there are only about 18 known acetyltransferases and 18 known deacetylases for thousands of acetylation sites.

    “The approved KDAC inhibitors are largely non-selective, as there are only ~18 known acetyltransferases and ~18 known deacetylases for thousands of acetylation sites [25–27].”

    From Acetylation: a new target for protein degradation in cancer (2025) · cites this paper as [25]

    The Lysine deacetylases section says the human genome encodes 18 KDACs, and the Introduction reports thousands of acetylation sites. But the Lysine acetyltransferases section says the number of bona fide KATs is unclear and identifies 13 well-characterized KATs, not approximately 18. The Therapeutic targeting of acetylation section lists approved KDAC inhibitors but does not say they are largely non-selective or attribute their selectivity to the number of enzymes and sites.

  • Chromatin modification factors including KATs GCN5, HAT1, and RTT109, and KDACs SET3, HAD1, RPD31, and HST3 are implicated in virulence processes of Candida species, including filamentous growth and biofilm formation, as well as in their resistance and sensitivity to antifungal drugs.

    “Chromatin modification factors, including KATs such as GCN5, HAT1, and RTT109, as well as KDACs like SET3, HAD1, RPD31, and HST3, are implicated in the virulence processes of Candida species, including filamentous growth and biofilm formation, as well as in their resistance and sensitivity to antifungal drugs (14–16).”

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.
