FUBP1 is a core splicing factor that facilitates 3' splice site recognition and splicing of long introns [In vivo iCLIP]

Project description:Splicing is a central process in metazoans and greatly expands their proteome by alternative splicing of pre-mRNA transcripts. An essential regulatory step during early spliceosome assembly is the recognition of cis-regulatory RNA motifs in pre-mRNAs. Here, we identified the RNA binding protein FUBP1 as a novel core splicing factor with a ubiquitous footprint on pre-mRNAs. FUBP1 binds to a previously unknown cis-regulatory motif upstream of the branch point of human introns. We show that FUBP1 binds and stabilises known 3' splice site components such as the essential splicing factor U2AF2. FUBP1 mutant cell lines and patient data indicate that FUBP1 is particularly relevant for efficient splicing of exons flanked by long introns. In addition to its role at the 3’ splice site, FUBP1 shows multiple interactions with U1 snRNP- associated proteins. This demonstrates an important role for FUBP1 in splice site bridging in the context of long introns.

iCLIP-based modeling uncovers 3’ splice site definition: how U2AF65 specificity relies on regulation by co-factors [in vitro iCLIP]

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.
