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.

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

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

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.

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.

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.

Genomic nucleosome positions determine DNA accessibility to regulatory molecules, and thus modulate gene expression. Nucleosome positioning can be characterised by the location of the nucleosome centres, average occupancy landscapes, the stability of individual nucleosomes, and integral parameters such as the nucleosome repeat length.

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.

Nucleosomal TATA-switch: Competing orientations of TATA on the nucleosome
Gene, 2013Transcription is known to be affected by the rotational setting of the transcription response elements within nucleosomes. We studied the rotational positioning of the TATA box, the most universal promoter motif. We applied a bioinformatic high-resolution nucleosome mapping technique to eukaryotic promoters.
