Bohla D, Herold M, Panzer I, Buxa MK, Ali T, Demmers J, Kr├╝ger 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. PubMed PMID: 25247414; PubMed Central PMCID: PMC4172637.

From the abstract: "... Here, we wanted to identify chromatin modification and remodelling factors required for an enhancer blocking function. 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. ..."

Localization of CPTI collection of YFP-trap proteins

Lye CM, Naylor HW, Sanson B. Subcellular localisations of the CPTI collection of YFP-tagged proteins in Drosophila embryos. Development. 2014 Oct;141(20):4006-17. PMID: 25294944.

From the abstract:  "... The Cambridge Protein Trap Consortium generated, via piggyBac transposition, over 600 novel YFP-trap proteins tagging just under 400 Drosophila loci. Here, we characterise the subcellular localisations and expression patterns of these insertions, called the CPTI lines, in Drosophila embryos. ..."

Drosophila cell-based genome-wide screen related to Parkinson's disease

Ivatt RM, Sanchez-Martinez A, Godena VK, Brown S, Ziviani E, Whitworth AJ. Genome-wide RNAi screen identifies the Parkinson disease GWAS risk locus SREBF1 as a regulator of mitophagy. Proc Natl Acad Sci U S A. 2014 Jun 10;111(23):8494-9. PMID: 24912190; PubMed Central PMCID: PMC4060696.  

From the abstract: "... We undertook a genome-wide RNAi screen as an unbiased approach to identify genes regulating the PINK1/Parkin pathway. We identified several genes that have a conserved function in promoting mitochondrial translocation of Parkin and subsequent mitophagy, most notably sterol regulatory element binding transcription factor 1 (SREBF1), F-box and WD40 domain protein 7 (FBXW7), and other components of the lipogenesis pathway. ..."
