Project description:The homozygous of mutants of Arabidopsis gene (AT1G60900) are early flower. This gene encodes a homolog of yeast U2AF65 which is involved in pre-mRNA splicing of target genes. To assay the introns characters of target genes of this protein in Arabidopsis thaliana, the 10-day seedlings of wild type and atu2af65b mutant were used for RNA-Seq.

Project description:iCLIP experiment to assess the binding of the highly abundant nuclear RNA-binding protein hnRNP C and core splicing factor U2AF65 on a genomic scale. To investigate how both proteins compete for binding at a subset of sites, U2AF65 iCLIP experiments were performed from both HNRNPC knockdown and control HeLa cells.

Project description:Alternative splicing generates distinct mRNA isoforms and is crucial for proteome diversity in eukaryotes. The RNA-binding protein (RBP) U2AF65 is central to splicing decisions, as it recognizes 3' splice sites and recruits the spliceosome. We established 'in vitro iCLIP' experiments, in which recombinant RBPs are incubated with long transcripts, to study how U2AF65 recognizes RNA sequences and how this is modulated by trans-acting RBPs. We quantitatively measure U2AF65 affinities at hundreds of binding sites, and compare in vitro and in vivo binding landscapes by mathematical modelling. We find that trans-acting RBPs extensively regulate U2AF65 binding in vivo, including enhanced recruitment to 3' splice sites and clearance of intronic regions. Using machine learning, we identify novel trans-acting RBPs (including FUBP1, BRUNOL6 and PCBP1) that modulate U2AF65 binding and affect splicing outcomes. Our study offers a blueprint for the high-throughput characterization of in vitro mRNP assembly and in vivo splicing regulation.

Project description:U2AF65 is an essential splicing factor involved in the 3'splice site recognition dureing the first steps of spliceosome assembly. In addition, this protein has nucleocytoplasmic shuttling activity and the Drosophila homologue has been implicated in mRNA export. We have used microarray hybridization coupled to RNA immunoprecipitation from HeLa cell cytoplasmic extracts using anti-U2AF65 antibodies to identify mRNA molecules associated with the U2AF65 splicing factor Sample preparation methods (Gama-Carvalho et al, 2006, submitted) Suspension HeLa cells were grown in DMEM, 10% FCS, Pen/Strep and split 1:2 the day before harvesting. Post-nuclear cytoplasmic extracts were obtained as described (Herbert and Hecht 1999), using 5x107 cells/ml of lysis buffer. mRNAs were isolated by immunoprecipitation from 200ul of precleared HeLa cell extract, using the anti-U2AF65 MC3 mAb (Gama-Carvalho, Krauss et al. 1997) or the Bb7 anti-PTB mAb (ATCC) for 2h at 4ºC. Immune complexes were precipitated with a slurry with 50% of protein A/protein G agarose beads (Amersham), blocked with 100ug/ul of tRNA and RNAse free BSA (Ambion), by rotating for 1h at 4ºC and washed with lysis buffer. Complexes bound to the beads were eluted with TES buffer (10mM Tris, 0.5M EDTA, 0.5% SDS, pH 8.0) by heating at 65ºC for 10 minutes and Trizol extracted. Polyadenilated RNA in the cell extract (input) and in the immunoprecipitation sample was reverse transcribed, end-tagged and PCR amplified using the Super SMART PCR cDNA synthesis kit from Clontech, following manufacturer instructions. 1ug of input or precipitated RNA was used per RT-PCR reaction to produce samples for microarray hybridization. For each set of samples (input and immunoprecipitated) a 100ul test PCR reaction was performed according to manufacturer instructions and analyzed by agarose gel electrophoresis to select ideal conditions for amplification in the linear range. PCR reactions were pooled to obtain enough material for microarray hybridization. 15ug of PCR amplified cDNA from input and immunoprecipitated samples were fragmented, end labeled with biotin and hybridized to Affymetrix GeneChip Human Genome U133 Plus 2.0 Arrays as described (Brodsky, Meyer et al. 2005), following standard Affymetrix hybridization protocols.
