Histone chaperone specificity in Rtt109 activation [PDF]

Nature Structural & Molecular Biology, 2008
Rtt109 is a histone acetyltransferase that requires a histone chaperone for the acetylation of histone 3 at lysine 56 (H3K56). Rtt109 forms a complex with the chaperone Vps75 in vivo and is implicated in DNA replication and repair. Here we show that both Rtt109 and Vps75 bind histones with high affinity, but only the complex is efficient for catalysis.

H3–H4 histone chaperones and cancer

Current Opinion in Genetics & Development, 2022
Histone chaperones are key regulators of chromatin structure and function. Their frequent mis-regulation in various cancers can impact tumor initiation and progression. Here, we focus on H3-H4 histone chaperones to highlight recent studies concerning their roles in several cancers thereby expanding on previous reports illustrating their functions as ...

ATP-dependent chromatosome remodeling [PDF]

, 2008
Chromatin serves to package, protect and organize the complex eukaryotic genomes to assure their stable inheritance over many cell generations. At the same time, chromatin must be dynamic to allow continued use of DNA during a cell's lifetime.

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

Nature 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.

Nucleus-specific linker histones Hho1 and Mlh1 form distinct protein interactions during growth, starvation and development in Tetrahymena thermophila [PDF]

, 2019
Chromatin organization influences most aspects of gene expression regulation. The linker histone H1, along with the core histones, is a key component of eukaryotic chromatin.

Histone chaperones link histone nuclear import and chromatin assembly [PDF]

Biochimica et Biophysica Acta (BBA) - Gene Regulatory Mechanisms, 2012
Histone chaperones are proteins that shield histones from nonspecific interactions until they are assembled into chromatin. After their synthesis in the cytoplasm, histones are bound by different histone chaperones, subjected to a series of posttranslational modifications and imported into the nucleus.

Statistical-mechanical lattice models for protein-DNA binding in chromatin [PDF]

, 2010
Statistical-mechanical lattice models for protein-DNA binding are well established as a method to describe complex ligand binding equilibriums measured in vitro with purified DNA and protein components. Recently, a new field of applications has opened up

The histone shuffle: histone chaperones in an energetic dance [PDF]

Trends in Biochemical Sciences, 2010
Our genetic information is tightly packaged into a rather ingenious nucleoprotein complex called chromatin in a manner that enables it to be rapidly accessed during genomic processes. Formation of the nucleosome, which is the fundamental unit of chromatin, occurs via a stepwise process that is reversed to enable the disassembly of nucleosomes.

Histone Recycling by FACT and Spt6 during Transcription Prevents the Scrambling of Histone Modifications

Cell Reports, 2019
Summary: Genomic DNA is framed by additional layers of information, referred to as the epigenome. Epigenomic marks such as DNA methylation, histone modifications, and histone variants are concentrated on specific genomic sites, where they can both ...

Histone acetylation-independent transcription stimulation by a histone chaperone [PDF]

Nucleic Acids Research, 2006
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.
