RNA-seq analysis of the eight Drosophila SR protein family members

Project description:Using RNA-seq, we characterize the global AS regulation of the eight Drosophila SR protein family members RNA-seq experiments on two replicate samples from 8 individual SR protein knockdown (exptGroup=S), two replicates of simultaneous SR protein knockdown (XL6:B52 & SC35:B52) (exptGroup=D). Each exptGroup includes duplicate of its own non-specific (NS) controls.

iCLIP seq reveals distribution of genome-wide SR protein-RNA binding

Project description:We identified the precise genome-wide binding sites for all SR proteins, using iCLIP-seq SR proteins were encoded on stable transgenes, transfected in S2 cells, FLAG-tag immunopurified, and the bound RNA purified and subjected to RNA-seq. The resulting reads (CLIP tags) were aligned to the Drosophila genome and generated 38,695-5,900,000 unique CLIP tags for each SR-protein replicate.

Transcriptome-wide mapping of RNA:protein interactions of seven SR proteins and NXF1 in P19 cells by iCLIP

Project description:We used GFP-tagged SR proteins expressed at endogenous levels and iCLIP to identify and compare endogenous RNA targets of individual SR proteins, map the preferential sites of binding, compare binding pattern and binding motifs between family members and to NXF1 and quantify binding of SR proteins and NXF1 to spliced versus unspliced RNAs to study the role of SR proteins in mRNA export via NXF1.

Knockdown of SR protein family in P19 cells and RNA-seq of cytoplasmic and whole cell polyA+ RNA

Project description:Our data suggest that all SR proteins contribute to mRNA export via NXF1. To identify endogenous export targets we depleted all seven SR proteins individually from P19 WT cells prepared cytoplasmic fractions. We sequenced the cytoplasmic fraction and as a control whole celll RNA from the identical sample. Knockdown of seven SR Proteins plus control, total RNA and cytoplasmic RNA, polyA+ enriched, 2 biological replicates per condition, 2 technical replicates per condition

Genome-wide Analysis Reveals SR Protein Cooperation and Competition in Regulated Splicing

Project description:SR proteins are well-characterized RNA binding proteins that promote exon inclusion by binding to exonic splicing enhancers (ESEs). However, it has been unclear whether regulatory rules deduced on model genes apply generally to activities of SR proteins in the cell. Here, we report global analyses of two prototypical SR proteins SRSF1 (SF2/ASF) and SRSF2 (SC35) using splicing-sensitive arrays and CLIP-seq on mouse embryo fibroblasts (MEFs). Unexpectedly, we find that these SR proteins promote both inclusion and skipping of exons in vivo, but their binding patterns do not explain such opposite responses. Further analyses reveal that loss of one SR protein is accompanied by coordinated loss or compensatory gain in the interaction of other SR proteins at the affected exons. Therefore, specific effects on regulated splicing by one SR protein actually depend on a complex set of relationships with multiple other SR proteins in mammalian genomes.

RNA-seq of sexed adult tissues/body parts from eight Drosophila species

Project description:This data set contains polyA+ transcriptional profiling of sexed adult tissues/body parts and whole adults of eight Drosophila species: Drosophila melanogaster (FBsp00000001) from two strains [w1118 (FBst0005905) and Oregon-R (FBst0025211)], Drosophila yakuba (FBsp00000254), Drosophila ananassae (FBsp00000052), Drosophila pseudoobscura (FBsp00000201), Drosophila persimilis (FBsp00000188), Drosophila willistoni (FBsp00000253), Drosophila mojavensis (FBsp00000160), and Drosophila virilis (FBsp00000251). It is worth noting that the Samples (856) section of this series page only lists the top 500 samples, and the rest of the 356 samples are not shown in the list but are available in GEO by putting the GSM ID in the search box at the top of the page. All raw data are available by clicking the SRP108530 link (SRA section). It is noteworthy that all of the fourth replicate of our samples are included in the last 356 samples in this series. Please see the supplementary file "All_samples_with_title.txt" for a complete list of GSM IDs and sample titles.
