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:The dynamic regulation of transcriptome requires coordinated participation of multiple RNA binding proteins (RBPs) in RNA processing. Dysregulated RNA processing, such as aberrant alternative splicing, is implicated in many cancers. Therefore, it is critical to explore the cancer-related RNA processing regulation and the underlying mechanisms. Many RBPs lack classical RNA-binding domains and their functions in RNA processing regulation remain unclear. Through an unbiased transcriptome-wide analysis, we report DAP3 binds ubiquitously to endogenous RNAs in vivo and its depletion reshapes the alternative splicing landscape in cancer cells. Mechanistically, we show DAP3 coordinates splicing regulatory networks, not only via mediating the formation of ribonucleoprotein (RNP) complexes, but also via modulating splicing of numerous splicing factors. Specific DAP3-regulated splicing changes such as non-productive splicing of WSB1 and RBM6, play important roles in tumorigenesis. Together, these findings provide critical mechanistic insights into the molecular functions of DAP3 in cancer development as a master regulator of RNA processing.
