Maintenance of cell fates and regulation of the histone variant H3.3 by TLK kinase in Caenorhabditis elegans

open access: yesBiology Open, 2019
Cell-fate maintenance is important to preserve the variety of cell types that are essential for the formation and function of tissues. We previously showed that the acetylated histone-binding protein BET-1 maintains cell fate by recruiting the histone ...

A natural histone H2A variant lacking the Bub1 phosphorylation site and regulated depletion of centromeric histone CENP-A foster evolvability in Candida albicans [PDF]

open access: yes, 2019
Eukaryotes have evolved elaborate mechanisms to ensure that chromosomes segregate with high fidelity during mitosis and meiosis, and yet specific aneuploidies can be adaptive during environmental stress.

Cleavage-embryo genes and transposable elements are regulated by histone variant H2A.X

open access: yesThe Journal of Reproduction and Development, 2021
During mammalian preimplantation development, stimulation of zygotic genome activation (ZGA) and transposable elements (TEs) shapes totipotency profiling.

Histone Variants in Metazoan Development [PDF]

open access: yesDevelopmental Cell, 2010
Embryonic development is regulated by both genetic and epigenetic mechanisms, with nearly all DNA-templated processes influenced by chromatin architecture. Sequence variations in histone proteins, core components of chromatin, provide a means to generate diversity in the chromatin structure, resulting in distinct and profound biological outcomes in the

Histone variants in pluripotency and disease [PDF]

open access: yesDevelopment, 2013
Most histones are assembled into nucleosomes during replication to package genomic DNA. However, several variant histones are deposited independently of replication at particular regions of chromosomes. Such histone variants include cenH3, which forms the nucleosomal foundation for the centromere, and H3.3, which replaces histones that are lost during ...

Probing the (H3-H4)(2) histone tetramer structure using pulsed EPR spectroscopy combined with site-directed spin labelling [PDF]

open access: yes, 2009
The (H3-H4)(2) histone tetramer forms the central core of nucleosomes and, as such, plays a prominent role in assembly, disassembly and positioning of nucleosomes.

Improved tools for efficient mapping of fission yeast genes:identification of microtubule nucleation modifier mod22-1 as an allele of chromatin- remodelling factor gene swr1 [PDF]

open access: yes, 2008
Fission yeast genes identified in genetic screens are usually cloned by transformation of mutants with plasmid libraries. However, for some genes this can be difficult, and positional cloning approaches are required.

Focus on histone variant H2AX: To be or not to be [PDF]

open access: yesFEBS Letters, 2010
Phosphorylation of histone variant H2AX at serine 139, named γH2AX, has been widely used as a sensitive marker for DNA double‐strand breaks (DSBs). γH2AX is required for the accumulation of many DNA damage response (DDR) proteins at DSBs. Thus it is believed to be the principal signaling protein involved in DDR and to play an important role in DNA ...

Fine mapping of posttranslational modifications of the linker histone H1 from Drosophila melanogaster. [PDF]

open access: yes, 2008
The linker histone H1 binds to the DNA in between adjacent nucleosomes and contributes to chromatin organization and transcriptional control. It is known that H1 carries diverse posttranslational modifications (PTMs), including phosphorylation, lysine ...

Functional Redundancy and Feedback Regulation between Canonical Histone H3 and Variant Histone H3.3 in Drosophila [PDF]

open access: yes, 2019
Animal cell chromatin contains two types of histones: canonical and variant. Although canonical and variant histones have similar structures, their expression and incorporation into chromatin are regulated differently.
