Nucleosome structure(s) and stability: variations on a theme. Journal Article uri icon

Overview

abstract

  • Chromatin is a highly regulated, modular nucleoprotein complex that is central to many processes in eukaryotes. The organization of DNA into nucleosomes and higher-order structures has profound implications for DNA accessibility. Alternative structural states of the nucleosome, and the thermodynamic parameters governing its assembly and disassembly, need to be considered in order to understand how access to nucleosomal DNA is regulated. In this review, we provide a brief historical account of how the overriding perception regarding aspects of nucleosome structure has changed over the past thirty years. We discuss recent technical advances regarding nucleosome structure and its physical characterization and review the evidence for alternative nucleosome conformations and their implications for nucleosome and chromatin dynamics.
