Stage-specific histone modification profiles reveal global transitions in the Xenopus embryonic epigenome. [PDF]

open access: yes, 2011
Vertebrate embryos are derived from a transitory pool of pluripotent cells. By the process of embryonic induction, these precursor cells are assigned to specific fates and differentiation programs.

The Hypersaline Archaeal Histones HpyA and HstA Are DNA Binding Proteins That Defy Categorization According to Commonly Used Functional Criteria

open access: yesmBio, 2023
Histone proteins are found across diverse lineages of Archaea, many of which package DNA and form chromatin. However, previous research has led to the hypothesis that the histone-like proteins of high-salt-adapted archaea, or halophiles, function ...

Extracellular Acetylated Histone 3.3 Induces Inflammation and Lung Tissue Damage

open access: yesBiomolecules, 2023
Extracellular histones, part of the protein group known as damage-associated molecular patterns (DAMPs), are released from damaged or dying cells and can instigate cellular toxicity.

ATP-dependent chromatosome remodeling [PDF]

open access: yes, 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.

The role of histones in the immune responses of aquatic invertebrates [PDF]

open access: yesInvertebrate Survival Journal, 2013
Histones are primary components of eukaryotic chromatin and highly abundant in all animal cells. In addition to their important role in chromatin structure and transcriptional regulation, histones contribute to innate immune responses. In several aquatic

LPS-Challenged Macrophages Release Microvesicles Coated With Histones

open access: yesFrontiers in Immunology, 2018
Histones are the protein component of nucleosomes, which are the basic packing unit of chromatin. However, histones are also found in the blood, both as components of nucleosomes leaked out from dead cells, or expelled from neutrophils in the active ...

The replacement histone H2A.Z in a hyperacetylated form is a feature of active genes in the chicken [PDF]

open access: yes, 2005
The replacement histone H2A.Z is variously reported as being linked to gene expression and preventing the spread of heterochromatin in yeast, or concentrated at heterochromatin in mammals.

Antifungal Activity of Antimicrobial Peptides and Proteins against Aspergillus fumigatus

open access: yesJournal of Fungi, 2020
Antimicrobial peptides and proteins (AMPs) provide an important line of defence against invading microorganisms. However, the activity of AMPs against the human fungal pathogen Aspergillus fumigatus remains poorly understood.

The Histone Database: an integrated resource for histones and histone fold-containing proteins [PDF]

open access: yesDatabase, 2011
Eukaryotic chromatin is composed of DNA and protein components-core histones-that act to compactly pack the DNA into nucleosomes, the fundamental building blocks of chromatin. These nucleosomes are connected to adjacent nucleosomes by linker histones. Nucleosomes are highly dynamic and, through various core histone post-translational modifications and ...

Phasor Histone FLIM-FRET Microscopy Maps Nuclear-Wide Nanoscale Chromatin Architecture With Respect to Genetically Induced DNA Double-Strand Breaks

open access: yesFrontiers in Genetics, 2021
A DNA double-strand break (DSB) takes place in the context of chromatin, and there is increasing evidence for chromatin structure to play a functional role in DSB signaling and repair.
