Abstract

Acetylation of histone and non-histone proteins is a post-translational modification mostly associated with activation of gene transcription. The first histone acetyltransferase (HAT) identified as modifying newly synthesized histone H4 in yeast was a type B HAT named HAT1. Although it was the first HAT to be discovered, HAT1 remains one of the most poorly studied enzymes in its class. In addition to its well-established role in the cytoplasm, recent findings have revealed new and intriguing aspects of the function of HAT1 in the nucleus. Several studies have described its involvement in regulating different pathways associated with a wide range of diseases, including cancer. This review focuses on our current understanding of HAT1, highlighting its importance in regulating chromatin replication and gene expression. This previously unknown role for HAT1 opens up novel scenarios in which further studies will be required to better understand its function.

  • Major HAT families include GNAT, p300/CBP, MYST, and Rtt109.

    “Major HAT families include GNAT, p300/CBP, MYST, and Rtt109 (Poziello et al., 2021; Sabnis, 2021; Di Cerbo and Schneider, 2013).”

    From Histone modifications and depression: epigenetic mechanisms, therapeutic targets, and translational outlook (2026) · cites this paper as Poziello et al., 2021

    The Introduction (page unavailable) identifies GNAT, p300/CBP, and MYST as three main families of mammalian HATs. It does not include Rtt109 in that classification; Rtt109 appears only in a cited reference title. Thus the source supports three of the four families listed, but not the full claim.

  • Acetylation is catalyzed by histone acetyltransferases, which neutralize lysine residues, loosen DNA-histone interactions, and promote chromatin accessibility.

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.
