Modification of histone tails, by acetylation, methylation or phosphorylation, affects the local chromatin structure and the transcriptional regulation of adjacent genes. Pericentric heterochromatin ...

Histone variants help establish DNA methylation at transposons (jumping genes) while preventing this epigenetic modification from spreading to essential genes in plants, a study from the Institute of ...

Histone modifications constitute a dynamic layer of epigenetic regulation that shapes gene expression programmes central to fungal virulence, morphogenesis and drug resistance. In pathogenic fungi ...

In eukaryotes, genomic DNA, which is a very long double helix containing all the genetic information, wraps around a globular protein called a histone and folds it many times before being contained ...

Every cell type in the human body carries the same approximately 3.2 billion base pairs of DNA, yet a liver cell behaves nothing like a neuron. The epigenome explains this difference: in each cell, ...

Illustration of H2B or H3 tail-less nucleosomes. Nucleosomes lacking H2B and H3 tails exhibit weakened interactions between histone tails and nucleosomal DNA, leading to less stable nucleosome ...

What is the histone code? Different chemical marks, such as acetylation, methylation, or phosphorylation, are made to numerous residues on the N-terminal tails of histone proteins. Some posit that ...
