Histone–DNA interactions in a nucleosome represent a fundamental level of gene regulation through which nucleosome stability, DNA accessibility, transcription, and chromatin higher …

DNA histone interaction refers to the process where histone modifications, such as acetylation and methylation, influence the structure of chromatin by altering the accessibility of …

Oct 10, 2011 · An ∼20% fraction of histone tail interactions rearranged from the outer to the inner DNA turn during unwrapping of the outer DNA turn at ∼12 ns, resulting in a moderate …

The molecular recognition of nucleosomes by chromatin factors frequently occurs through the interactions with the nucleosomal and linker DNA, histone tails, histone globular domains [2–4] …

Nov 11, 2021 · Eukaryotic DNA is packaged in the form of chromatin, where approximately 150 base pairs of DNA is wrapped around an octameric core of histone proteins to form the …

nucleosome. These histone “tails” are targets of posttranslational modifications and play an important role in modulating the interaction of histones with other chromo-somal proteins …

(C) Effects of histone acylations on DNA‐histone interaction strength and nucleosome stability can be measured in an optical tweezer setup, where mononucleosomes or nucleosomal arrays …

6 days ago · The interactions between DNA and histone with absorption energy can wind the DNA around the histone core, forming partially wrapped and mis-wrapped structures, and finally …

Histone-DNA interactions in chromatin are, however, highly complex in the sense that five different proteins interact with each other and with DNA to form a stoicheiometric complex in …

Histones are associated with DNA to form nucleosome essential for chromatin structure and major nuclear processes like gene regulation and expression. Histones consist of H1, H2A, H2B and …

One example is the acetylation of certain lysine histone residues by lysine (K) histone acetyltransferases (KATs), which leads to the nullification of the positive charge of lysine …

Jan 11, 2009 · By unzipping DNA in single nucleosomes, a detailed map at near base pair resolution of histone-DNA interactions is now provided, suggesting that interaction with the two …

Mar 19, 2021 · To elucidate the properties of human histone interactions on the large scale, we perform a comprehensive mapping of human histone interaction networks by using data from …

Oct 19, 2011 · The nucleosome complex of DNA wrapped around a histone protein octamer organizes the genome of eukaryotes and regulates the access of protein factors to the DNA. …

into the spatiotemporal dynamics of DNA-histone interactions. The researchers looked at the interaction between DNA and a histone called H2A, one of the five main histones. To check the ...

We conclude that a total of approximately 168 base pairs (bp) of DNA can interact with the histone core under appropriate solution conditions, even in the absence of lysine-rich histones. The …

We have utilized micrococcal nuclease digestion and thermal denaturation studies to investigate the binding of DNA to the histone core of the nucleosome. We conclude that a total of …
