Nucleosome is the basic subunit of the chromatin, which organizes the genomic DNA within the cell nucleus. It was understood in the last decade that beside the DNA compaction it plays an important role in the regulation of the gene expression. In its intact form, the nucleosome represents an important mechanical barrier and, among others, it prevents ...

Recent studies have elucidated molecular mechanisms underlying the transcriptional control of metabolism in complex metabolic disorders such as metabolic syndrome and atherosclerosis. Chromatin immunoprecipitation (ChIP) is an important technique to study protein-DNA interactions in vivo.

Recent progress has been made in the understanding of the physical properties of chromatin—the dense complex of DNA and histone proteins that occupies the nuclei of plant and animal cells. Here I will focus on the two lowest levels of the hierarchy of DNA folding into the chromatin complex. (i) The nucleosome, the chromatin repeating unit consisting of

Annual Review of Genetics, 2006
Active and silenced chromatin domains are often in close juxtaposition to one another, and enhancer and silencer elements operate over large distances to regulate the genes in these domains. The lack of promiscuity in the function of these elements suggests that active mechanisms exist to restrict their activity.

Immunoprecipitation of chromatin
1996Publisher Summary This chapter discusses the immunoprecipitation of chromatin. The chapter discusses three standard protocols, all of which are used to analyze the role of specific proteins within defined regions of the eukaryotic genome. It analyzes both the DNA and the protein after immunoprecipitation.

The nuclear chromatin of trypanosomes is organised in the form of nucleosome filaments. When soluble chromatin is prepared under suitable conditions, a regular array of nucleosomes can be shown by electron microscopy. Chromatin of blood stream as well as procyclic culture forms of Trypanosoma brucei brucei and of T.

A complete understanding of the structure-function relationships of chromatin requires extending primarily one dimensional information, obtained from molecular genetic techniques and based on the underlying linear DNA sequence, to the three dimensional conformation.

Physico-chemical experiments show that histones are not evenly distributed in chromatin. About half of the DNA is “open” and not covered with proteins.

Active genes are packaged into an altered nucleosome structure forming a chromosomal domain defined by increased sensitivity to nucleases. This structure, reflecting a potential for transcription, contains sites hypersensitive to nuclease digestion adjacent to the coding regions and may also be distinguished by specific non-histone proteins, variant or
