The histone chaperone FACT facilitates heterochromatin spreading by regulating histone turnover and H3K9 methylation states [PDF]
Summary: Heterochromatin formation requires three distinct steps: nucleation, self-propagation (spreading) along the chromosome, and faithful maintenance after each replication cycle.

The histone chaperone function of Daxx is dispensable for embryonic development [PDF]
Daxx functions as a histone chaperone for the histone H3 variant, H3.3, and is essential for embryonic development. Daxx interacts with Atrx to form a protein complex that deposits H3.3 into heterochromatic regions of the genome, including centromeres ...

Histone Chaperone Nrp1 Mutation Affects the Acetylation of H3K56 in Tetrahymena thermophila [PDF]
Histone modification and nucleosome assembly are mainly regulated by various histone-modifying enzymes and chaperones. The roles of histone-modification enzymes have been well analyzed, but the molecular mechanism of histone chaperones in histone ...

Histone acetylation-independent transcription stimulation by a histone chaperone [PDF]
Histone chaperones are thought to be important for maintaining the physiological activity of histones; however, their exact roles are not fully understood. The physiological function of template activating factor (TAF)-I, one of the histone chaperones, also remains unclear; however, its biochemical properties have been well studied.

TSPY-like 2, Beyond the Histone Chaperone Role [PDF]
Chromatin is a dynamic cellular structure basically constituted by nucleosomes, which consist of a DNA sequence wrapped around an octameric histones core.

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

The histone chaperone nucleoplasmin (Npm) stores histones H2A/H2B in the egg and embryo. Here, the authors use NMR to show that Npm’s intrinsically disordered tail domain controls histone binding at an acidic stretch, which is autoregulated through ...

New chaps in the histone chaperone arena [PDF]
Understanding exactly how chromatin is assembled is paramount to addressing how select histone modifications may be transmitted, a putative epigenetic process. In the June 15, 2010, issue of Genes & Development, Drané and colleagues (pp. 1253–1265) identified DAXX as a novel H3.3-specific chaperone.

Placing the HIRA Histone Chaperone Complex in the Chromatin Landscape
The HIRA chaperone complex, comprised of HIRA, UBN1, and CABIN1, collaborates with histone-binding protein ASF1a to incorporate histone variant H3.3 into chromatin in a DNA replication-independent manner.

The histone chaperone Spt6 coordinates histone H3K27 demethylation and myogenesis [PDF]
Histone chaperones affect chromatin structure and gene expression through interaction with histones and RNA polymerase II (PolII). Here, we report that the histone chaperone Spt6 counteracts H3K27me3, an epigenetic mark deposited by the Polycomb Repressive Complex 2 (PRC2) and associated with transcriptional repression.
