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 ...

Chemical changes to histones, the proteins that help to pack and organize DNA inside cells, play a key role in determining what genes will be consistently activated over the course of an animal or ...

Schematic diagram illustrating the novel epigenetic pathway. The dual modification on histone variant H3.3 recruits CBX7, which brings the scaffold protein KAP1 to chromatin. KAP1 facilitates H3K9me3 ...

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

Histone modification is an epigenetic mechanism that regulates gene expression by altering chromatin structure and DNA accessibility for transcription. Histone modification is regulated by various ...

The accurate distribution of chromosomes in an oocyte is essential for the correct transmission of genetic information to the next generation. Now, researchers from Kyushu University have demonstrated ...

In a recent study published in the journal Science Advances, a group of researchers investigated the role of histone modifications in human aging by developing and evaluating histone-specific age ...
