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. ..."

Study related to Abl kinase uses primary cultured cells

This is not an RNAi study but the approach taken might of interest to those thinking about cell-based studies. Liu L, Wu CF. Distinct effects of Abelson kinase mutations on myocytes and neurons in dissociated Drosophila embryonic cultures: mimicking of high temperature. PLoS One. 2014 Jan 21;9(1):e86438. PMID: 24466097; PMCID: PMC3897706. From the abstract: "... we observed myocyte fusion events and nerve-muscle contact formation between WT and Abl cells in mixed WT and Abl cultures derived from labeled embryos ..."
