A Spring 2010 Issue

Current Perspectives on Nucleosome Positioning
Journal of Biomolecular Structure & Dynamics, Volume 27, Issue #6, June 2010

As Editor-in-Chief, I am delighted that in the Spring of 2010 we will be coming out with a regular issue of JBSD dealing exclusively with the diverse thoughts and perspectives on the hot topic of nucleosome positioning. The positioning of nucleosomes on DNA controls the ability of the cellular machinery to access genetic messages. Generally, the messages become silent when and where the DNA wraps around the histones to form stable nucleosomes, and active when nucleosomes reposition by dynamically and reversibly sliding over the DNA. It is thought that enzymes and cofactors are recruited to regulate gene expression by modifying the DNA and histones via nucleosome repositioning. Correctly predicting the positioning of the nucleosome is accordingly linked to the 'activity' of the cell. Nucleosome positioning is driven primarily by sequence-dependent physicochemical properties of DNA (deformable versus 'rigid' sequences) and electrostatic interactions between the negatively charged DNA and the positively charged histone proteins (differences in charge build-up on AT-rich versus GC-rich sequences). The details of this sequence dependence are not known with any certainity, and leading laboratories in the world significantly disagree how genetic message is accessed and silenced.

In the twelve articles in this issue of JBSD, to be released in the spring of 2010, the scientists working in the area present their perspectives on the subject. Below are the title of the articles, their authors and affiliation.
