Histones and DNA can spontaneously associate to form the nucleosome subunits of eukaryotic chromatin, but two proteins which occur in the eukaryotic nucleus can facilitate nucleosome assembly and greatly extend the conditions which permit assembly to occur.

Remodeling and Repositioning of Nucleosomes in Nucleosomal Arrays
2018ATP-dependent nucleosome remodeling factors sculpt the nucleosomal landscape of eukaryotic chromatin. They deposit or evict nucleosomes or reposition them along DNA in a process termed nucleosome sliding. Remodeling has traditionally been analyzed using mononucleosomes as a model substrate.

In the 30 years since the discovery of the nucleosome, our picture of it has come into sharp focus. The recent high-resolution structures have provided a wealth of insight into the function of the nucleosome, but they are inherently static. Our current knowledge of how nucleosomes can be reconfigured dynamically is at a much earlier stage. Here, recent

The nucleosome is a large protein-nucleic acid complex involved in DNA packing and in controlling genetic information. Under circumstances described below, this component, normally sequestered in the cell nucleus, is released into the extracellular milieu and then is easily accessible to cells of the immune system.

Chromosome Research, 2006
It is now widely recognized that the packaging of genomic DNA together with core histones, linker histones, and other functional proteins into chromatin profoundly influences nuclear processes such as transcription, replication, repair and recombination. How chromatin structure modulates the expression and maintenance of knowledge encoded in eukaryotic

Phylogenomics of the nucleosome
Nature Structural & Molecular Biology, 2003Histones are best known as the architectural proteins that package the DNA of eukaryotic organisms, forming octameric nucleosome cores that the double helix wraps tightly around. Although histones have traditionally been viewed as slowly evolving scaffold proteins that lack diversification beyond their abundant tail modifications, recent studies have ...

Remodeling of Individual Nucleosomes in Nucleosome Arrays
Adenosin triphosphate (ATP)-dependent nucleosome remodeling factors sculpt the nucleosomal landscape of eukaryotic chromatin. They deposit, evict, or reposition nucleosomes along DNA in a process termed nucleosome sliding. Remodeling has traditionally been analyzed using mononucleosomes as a model substrate.Petra, Vizjak +2 more

Two new studies in Nature provide insight into the role of nucleosomes in gene regulation. One describes the genome-wide organization of nucleosomes and the other details how transcription factor binding to DNA is affected by the presence of nucleosomes.

The basic repeating unit of chromatin, the nucleosome, is known to play a critical role in regulating the process of gene transcription. The positioning of nucleosomes on a promoter is a significant determinant in its responsiveness to gene-inducing signals.

Structural Biology In eukaryotic cells, genomic DNA must be compacted to fit inside the nucleus. A key player in DNA packaging is the nucleosome, which comprises a segment of DNA wrapped around an octamer of histone proteins. During replication and transcription, nucleosomes must reposition themselves on the DNA.
