Nucleosome Mobility and the Maintenance of Nucleosome Positioning

Science, 1997
To study nucleosome mobility and positioning, the R3 lac repressor was used with an adenosine triphosphate (ATP)–dependent chromatin assembly system to establish the positioning of five nucleosomes, with one nucleosome located between two R3 lac operators. When R3 protein was dissociated from

Apoptosis and nucleosomes

Lupus, 2002
Drs Berden and Koutouzov presented evidence that nucleosomes are antigens in lupus pathogenesis and that apoptotic cells are the source of nucleosomes. Berden's group measured persistence of circulating nucleosomes and nucleosome–antibody complexes in autoimmune mice and demonstrated nucleosomaldepositionin skin of SLE patientsas well as in renal ...

Remodeling and Repositioning of Nucleosomes in Nucleosomal Arrays

2018
ATP-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.

Phylogenomics of the nucleosome

Nature Structural & Molecular Biology, 2003
Histones 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 ...

Nucleosome structure

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1978
Electron microscopic and biochemical results are presented supporting the following conclusions: (1) Two molecules of each histone H2A, H2B, H3 and H4 are necessary and sufficient to form a nucleosome with a diameter of 12.5± 1 nm and containing about 200 base pairs of DNA.
