Bohla D, Herold M, Panzer I, Buxa MK, Ali T, Demmers J, Krüger M, Scharfe M, Jarek M, Bartkuhn M, Renkawitz R. A Functional Insulator Screen Identifies NURF and dREAM Components to Be Required for Enhancer-Blocking. PLoS One. 2014 Sep 23;9(9):e107765. PMID: 25247414; PMCID: PMC4172637.
From the abstract: "... We used the well-studied Fab-8 insulator of the bithorax locus to apply a genome-wide RNAi screen for factors that contribute to the enhancer blocking function of CTCF and CP190. Among 78 genes required for optimal Fab-8 mediated enhancer blocking, all four components of the NURF complex as well as several subunits of the dREAM complex were most evident ..."
