Project description:The COP9 signalosome (CSN), an eight-subunit protein complex, is conserved in all higher eukaryotes. CSN intersects the ubiquitin-proteasome pathway, modulating signaling pathways controlling various aspects of development. We are using Drosophila as a model system to elucidate the function of this important complex. Transcriptome data was generated for four csn mutants, sampled at three developmental time points. Our results are highly reproducible, being confirmed using two different experimental setups that entail different microarrays and different controls. Our results indicate that the CSN acts as a transcriptional repressor during Drosophila development, resulting in achronic gene expression in the csn mutants. "Time shift" analysis with the publicly-available Drosophila transcriptome data indicates that genes repressed by the CSN are normally induced primarily during late embyogenesis, or during metamorphosis. These temporal shifts are likely due to the roles of the CSN in regulating transcription factors. A null mutation in CSN subunit 4, and hypomorphic mutations in csn5 lead to more severe defects than seen in the csn5null mutants strain, suggesting that CSN5 carries only some of the CSN function.

Project description:The 3' ends of most Drosophila melanogaster genes are poorly annotated or are determined by only a single EST or cDNA clone. To enhance the annotation of poly(A) site use in Drosophila, we performed deep sequencing on RNA isolated from 29 dissected tissues using an approach designed to enrich for poly(A) spanning reads. From these experiments, we identified 1.4 million poly(A) spanning reads leading to the identification of many new poly(A) sites and the identification of many tissue-specific poly(A) sites. For data usage terms and conditions, please refer to http://www.genome.gov/27528022 and http://www.genome.gov/Pages/Research/ENCODE/ENCODEDataReleasePolicyFinal2008.pdf RNA from 29 dissected Drosophila melanogaster tissues (in duplicate) were used to prepare polyA enriched RNA-Seq libraries. Briefly, total RNA was poly(A) selected, fragmented, and ligated to 5' and 3' RNA linkers. These libraries were amplified using Illumina paired-end primers, and subsequently reamplified using a 3' primer complementary to the 3' adapter but containing 6 Ts at the 3' end. The libraries were also multiplexed and up to 12 samples mixed per lane and sequenced on an Illumina GAIIx using paired-end 76 bp reads, or an illumina HiSeq 2000 using paired-end 100 bp reads. All reads were mapped to the Drosophila melanogaster genome to identify unmapped reads. Unmapped reads containing at least 10 A residues at the 3' end were identified, the terminal A residues trimmed, realigned to the genome to identify uniquely mapped reads. Such reads were identified as polyA spanning reads
