Histone Variants and Their Chaperones: An Emerging Epigenetic Mechanism in Neurodevelopment and Neurodevelopmental Disorders

open access: yesJournal of Integrative Neuroscience, 2023
Neurodevelopment is a highly regulated process that relies on the precise regulation of gene expression. Numerous epigenetic mechanisms contribute and cooperate to ensure the proper execution of developmental gene expression programs.

The Saccharomyces cerevisiae histone chaperone Rtt106 mediates the cell cycle recruitment of SWI/SNF and RSC to the HIR-dependent histone genes. [PDF]

open access: yesPLoS ONE, 2011
In Saccharomyces cerevisiae, three out of the four histone gene pairs (HTA1-HTB1, HHT1-HHF1, and HHT2-HHF2) are regulated by the HIR co-repressor complex.

Dynamic Activity of Histone H3-Specific Chaperone Complexes in Oncogenesis

open access: yesFrontiers in Oncology, 2022
Canonical histone H3.1 and variant H3.3 deposit at different sites of the chromatin via distinct histone chaperones. Histone H3.1 relies on chaperone CAF-1 to mediate replication-dependent nucleosome assembly during S-phase, while H3.3 variant is ...

The histone chaperone NASP maintains H3-H4 reservoirs in the early Drosophila embryo.

open access: yesPLoS Genetics, 2023
Histones are essential for chromatin packaging, and histone supply must be tightly regulated as excess histones are toxic. To drive the rapid cell cycles of the early embryo, however, excess histones are maternally deposited.

FACT modulates the conformations of histone H2A and H2B N-terminal tails within nucleosomes

open access: yesCommunications Biology, 2022
NMR experiments reveal distinct interactions of the histone chaperone, FACT, with the proximal and distal flexible histone H2A and H2B tails of the asymmetrically unwrapped nucleosome.

The Histone Chaperones SET/TAF‐1β and NPM1 Exhibit Conserved Functionality in Nucleosome Remodeling and Histone Eviction in a Cytochrome c‐Dependent Manner

open access: yesAdvanced Science, 2023
Chromatin homeostasis mediates essential processes in eukaryotes, where histone chaperones have emerged as major regulatory factors during DNA replication, repair, and transcription.

The histone chaperone FACT facilitates heterochromatin spreading by regulating histone turnover and H3K9 methylation states

open access: yesCell Reports, 2021
Summary: Heterochromatin formation requires three distinct steps: nucleation, self-propagation (spreading) along the chromosome, and faithful maintenance after each replication cycle.

Histone chaperone ASF1 mediates H3.3-H4 deposition in Arabidopsis

open access: yesNature Communications, 2022
Histone chaperones and chromatin remodelers control nucleosome dynamics. Here the authors show that the Arabidopsis ASF1 chaperone primarily supplies histone variants to the HIRA complex to ensure proper epigenetic gene regulation.

The histone chaperone ANP32B regulates chromatin incorporation of the atypical human histone variant macroH2A

open access: yesCell Reports, 2023
Summary: All vertebrate genomes encode for three large histone H2A variants that have an additional metabolite-binding globular macrodomain module, macroH2A. MacroH2A variants impact heterochromatin organization and transcription regulation and establish

HIRA, a DiGeorge Syndrome Candidate Gene, Confers Proper Chromatin Accessibility on HSCs and Supports All Stages of Hematopoiesis

open access: yesCell Reports, 2020
Summary: HIRA is a histone chaperone that deposits the histone variant H3.3 in transcriptionally active genes. In DiGeorge syndromes, a DNA stretch encompassing HIRA is deleted.
