The Drosophila histone variant H2A.V works in concert with HP1 to promote kinetochore-driven microtubule formation [PDF]

open access: yes, 2015
Unlike other organisms that have evolved distinct H2A variants for different functions, Drosophila melanogaster has just one variant which is capable of filling many roles.

Positional changes of pericentromeric heterochromatin and nucleoli in postmitotic Purkinje cells during murine cerebellum development [PDF]

open access: yes, 2004
Previous studies revealed changes of pericentromeric heterochromatin arrangements in postmitotic Purkinje cells (PCs) during postnatal development in the mouse cerebellum (Manuelidis, 1985; Martou and De Boni, 2000). Here, we performed vibratome sections

Differential expression and sex chromosome association of CHD3/4 and CHD5 during spermatogenesis [PDF]

open access: yes, 2014
ATP-dependent nucleosome remodelers of the CHD family play important roles in chromatin regulation during development and differentiation. The ubiquitously expressed CHD3 and CHD4 proteins are essential for stem cell function and serve to orchestrate ...

Genetic Dissection of Morphometric Traits Reveals That Phytochrome B Affects Nucleus Size and Heterochromatin Organization in Arabidopsis thaliana

open access: yesG3: Genes, Genomes, Genetics, 2017
Microscopically visible chromatin is partitioned into two major components in Arabidopsis thaliana nuclei. On one hand, chromocenters are conspicuous foci of highly condensed “heterochromatic” domains that contain mostly repeated sequences.

RNA from a simple-tandem repeat is required for sperm maturation and male fertility in Drosophila melanogaster. [PDF]

open access: yes, 2019
Tandemly-repeated DNAs, or satellites, are enriched in heterochromatic regions of eukaryotic genomes and contribute to nuclear structure and function. Some satellites are transcribed, but we lack direct evidence that specific satellite RNAs are required ...

Bundling up DNA

open access: yeseLife, 2018
Structures known as chromocenters, comprising satellite DNA and proteins such as D1 or HMGA1, help to contain DNA inside the nucleus between cell divisions.

Nuclear mechanostability emerges from satellite DNA condensation into chromocenters

open access: yes
ABSTRACT As the largest organelle, the nucleus endures significant mechanical stresses over the cellular lifespan, and mechanostability – the ability to resist deformation – is critical for genome integrity and function. Here, we reveal that nuclear mechanostability is an emergent property arising from the coalescence of satellite DNA ...

High-resolution mapping of h1 linker histone variants in embryonic stem cells. [PDF]

open access: yesPLoS Genetics, 2013
H1 linker histones facilitate higher-order chromatin folding and are essential for mammalian development. To achieve high-resolution mapping of H1 variants H1d and H1c in embryonic stem cells (ESCs), we have established a knock-in system and shown that ...
