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.

Salt-induced structural changes in nucleosomes
Nucleic Acids Research, 1977 Nucleosomes and oligonucleosomes were prepared by digestion of human pla-cental nuclei with staphlococccal nuclease and fractionated by gel filtration chromatography.

Nucleosome Mobility and the Maintenance of Nucleosome Positioning
Science, 1997To 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

CENP-A confers a reduction in height on octameric nucleosomes
Nature Structural and Molecular Biology, 2013 Nucleosomes with histone H3 replaced by CENP-A direct kinetochore assembly. CENP-A nucleosomes from human and Drosophila have been reported to have reduced heights as compared to canonical octameric H3 nucleosomes, thus suggesting a unique tetrameric ...

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

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 ...

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.

Abstract 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.
