Volume 14 Issue 11, November 2007

The cover, titled "Crosstalk", represents an artist's view of concepts such as information compression and multi-layered communication at work in chromatin. "Crosstalk" is an original work of art commissioned from Colleen Buzzard (http://www.colleenbuzzard.com). Archival materials on acid-free papers.pp 9861055, Primer p 1110

Overview

  • Starting with the structure of the nucleosome and continuing with histone modifications, chromatin-remodeling complexes, silencing factors and more, a detailed and dynamic picture of chromosomal DNA transactions has emerged.

  • Post-translational modification of histones can profoundly affect chromatin structure and function. The discovery that histone H3 Arg2 methylation is a widespread silencing modification that inhibits histone H3 Lys4 trimethylation extends our understanding of how active and silenced chromatin states are maintained.

Focus

  • In eukaryotes, the packaging of DNA by histones into chromatin has profound effects on transcription and other nuclear processes. Far from being a uniform set of 'beads on a string', chromatin structure is remodeled and even modified, altering the accessibility of packaged genes to the factors involved in their regulation. This special focus on chromatin features an Overview, six Reviews and a Perspective that describe how chromatin is built and subsequently altered at various structural levels, and the impact of these events on fundamental biological processes involving DNA.
