Good fences make good neighbors: barrier elements and genomic regulation.
In the genome, it is essential to maintain a physical barrier between active and inactive regions; however, the nature of this barrier has been elusive. In a recent issue of Molecular Cell, West et al. (2004) shed light on mechanisms underlying these molecular "fences."
