Determinants and dynamics of genome accessibility
In eukaryotes, all DNA-templated reactions occur in the context of chromatin. Nucleosome
packaging inherently restricts DNA accessibility for regulatory proteins but also provides an …

[HTML][HTML] Dynamics and memory of heterochromatin in living cells
Posttranslational histone modifications are important for gene regulation, yet the mode of
propagation and the contribution to heritable gene expression states remains controversial. To …

The histone chaperone CAF-1 safeguards somatic cell identity
Cellular differentiation involves profound remodelling of chromatic landscapes, yet the
mechanisms by which somatic cell identity is subsequently maintained remain incompletely …

Altered body iron distribution and microcytosis in mice deficient in iron regulatory protein 2 (IRP2)
Iron regulatory protein 2 (IRP2)-deficient mice have been reported to suffer from late-onset
neurodegeneration by an unknown mechanism. We report that young adult Irp2 -/- mice …

Variant histone H3. 3 is deposited at sites of nucleosomal displacement throughout transcribed genes while active histone modifications show a promoter-proximal …
C Wirbelauer, O Bell, D Schübeler - Genes & development, 2005 - genesdev.cshlp.org
Deposition of variant histones provides a mechanism to reset and to potentially specify
chromatin states. We determined the distribution of H3 and its variant H3.3 relative to chromatin …

Localized H3K36 methylation states define histone H4K16 acetylation during transcriptional elongation in Drosophila
Post‐translational modifications of histones are involved in transcript initiation and elongation.
Methylation of lysine 36 of histone H3 (H3K36me) resides promoter distal at transcribed …
