Organizing the genome: enhancers and insulators
Abstract
Enhancers can activate their target genes over large linear distances. Insulators can delimit the influence of an enhancer to an appropriate target. There are a number of intertwined mechanisms by which the regulatory functions of enhancers and insulators might be carried out at the level of the chromatin fiber. Recent evidence suggests that both enhancers and insulators participate in higher-order organization of chromatin in the nucleus and in localization of their regulated sequences to both subnuclear structures and compartments. Novel experimental approaches are helping to reveal the mechanisms underlying nuclear organization of developmentally regulated genes.
