Histone profiling reveals the H1.3 histone variant as a prognostic biomarker for pancreatic ductal adenocarcinoma [PDF]
Background Epigenetic alterations have been recognized as important contributors to the pathogenesis of PDAC. However, the role of histone variants in pancreatic tumor progression is still not completely understood.

Esperanto for histones: CENP-A, not CenH3, is the centromeric histone H3 variant [PDF]
The first centromeric protein identified in any species was CENP-A, a divergent member of the histone H3 family that was recognised by autoantibodies from patients with scleroderma-spectrum disease. It has recently been suggested to rename this protein CenH3.

Histone variants at a glance [PDF]
ABSTRACT Eukaryotic nucleosomes organize chromatin by wrapping 147 bp of DNA around a histone core particle comprising two molecules each of histone H2A, H2B, H3 and H4. The DNA entering and exiting the particle may be bound by the linker histone H1.

Histone variant H2A.W7 represses meiotic crossover formation in <i>Arabidopsis</i> heterochromatin. [PDF]
In eukaryotic genomes, DNA is packaged into nucleosomes to form chromatin. The incorporation of canonical or variant histones into nucleosomes confers different properties and influences chromatin structure to regulate cellular processes, including ...

Histones and histone variant families in prokaryotes. [PDF]
AbstractHistones are important chromatin-organizing proteins in eukaryotes and archaea. They form superhelical structures around which DNA is wrapped. Recent studies have shown that some archaea and bacteria contain alternative histones that exhibit different DNA binding properties, in addition to highly divergent sequences.

Histone Variants and Epigenetics [PDF]
Histones package and compact DNA by assembling into nucleosome core particles. Most histones are synthesized at S phase for rapid deposition behind replication forks. In addition, the replacement of histones deposited during S phase by variants that can be deposited independently of replication provide the most fundamental level of chromatin ...

Histone Variant H2A.Z Enhances Histone and Nucleosome Dynamics. [PDF]
Interchanging canonical histone H2A with variant H2A.Z in chromatin complexes is vital for the proper regulation of transcription, DNA damage repair, and centromere maintenance. However, the physical mechanisms underlying functional differences between H2A and H2A.Z complexes are unclear.

H2A Variants in Arabidopsis: Versatile Regulators of Genome Activity
The eukaryotic nucleosome prevents access to the genome. Convergently evolving histone isoforms, also called histone variants, form diverse families that are enriched over distinct features of plant genomes.

Dynamic Activity of Histone H3-Specific Chaperone Complexes in Oncogenesis
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 ...
