Project description:We generated a global analysis of Rbfox2 splicing regulation combined with a highly specific, single nucleotide-resolution Rbfox2 RNA binding map. We found that Rbfox2 regulates the splicing and expression of many previously unknown targets, and particularly a number of RNA binding proteins (RBPs), by modulating alternative splicing coupled-NMD. Based on our observations of RBP-Rbfox2 co-regulation with a polarity predicted by Rbfox2 binding, we propose a model whereby Rbfox2 tunes autoregulatory splicing events to control RBP expression levels and in turn alter their respective splicing networks. iCLIP for epitope-tagged Rbfox2 and control untagged Rbfox2; RNAseq of control and Rbfox2 knockdown in mouse embryonic stem cells

Project description:Networks of coordinated alternative splicing (AS) events play critical roles in development and disease. However, a comprehensive knowledge of the factors that regulate these networks is lacking. We describe a high-throughput system for systematically linking trans-acting factors to endogenous RNA regulation events. Using this system, we identify hundreds of factors associated with diverse regulatory layers that positively or negatively control AS events linked to cell fate. Remarkably, more than one third of the new regulators are transcription factors. Further analyses of the zinc finger protein Zfp871 and BTB/POZ domain transcription factor Nacc1, which regulate neural and stem cell AS programs, respectively, reveal roles in controlling the expression of specific splicing regulators. Surprisingly, these proteins also appear to regulate target AS programs via binding RNA. Our results thus uncover a large ‘missing cache’ of splicing regulators among annotated transcription factors, some of which dually regulate AS through direct and indirect mechanisms.

Project description:Alternative splicing—the production of multiple mRNA isoforms from a single gene—is regulated in part by RNA-binding proteins (RBPs). While the RBPs Tra2? and Tra2? have both been implicated in the regulation of alternative splicing, their relative contribution to this process are not well understood. Here we use iCLIP to identify Tra2? target exons in MDA-MB-231 cells. We find that simultaneous—but not individual—depletion of Tra2? and Tra2? induces substantial shifts in the splicing pattern of endogenous Tra2? target exons identified by iCLIP. We next use RNA-seq following joint Tra2 protein depletion to comprehensively identify Tra2 protein-dependent exons in MDA-MB-231 cells. Endogenous Tra2? binding sites were mapped across the MDA-MB-231 cell transcriptome in biological triplicate iCLIP experiments. RNA-seq was performed using three biological replicates of negative control siRNA treated MDA-MB-231 cells and three biological replicates of TRA2A and TRA2B siRNA treated MDA-MB-231 cells.
