Modulation of CTCF insulator function by transcription of a noncoding RNA

Dev Cell. 2008 Oct;15(4):489-90. doi: 10.1016/j.devcel.2008.09.013.

Abstract

CTCF plays diverse roles in the regulation of eukaryotic genes. A new study by Lefevre et al. in a recent issue of Molecular Cell reveals a novel mechanism in which noncoding RNA transcription and nucleosome repositioning evicts CTCF from a regulatory element to facilitate induction of a nearby gene.
