(Submitter supplied) 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. more...

(Submitter supplied) 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. more...

(Submitter supplied) Alternative splicing drives transcriptome and proteome diversification. While splicing regulatory proteins govern this process, their global mechanisms remain enigmatic. We generated high resolution transcriptome-wide protein-RNA interaction maps to determine how the splicing repressor hnRNPA1 influences the global association of spliceosome assembly factor U2AF2 and SRSF1 with pre-mRNA. We observed changes in the distribution of U2AF2 crosslinking sites relative to the 3’ splice sites of cassette exons but not constitutive exons upon hnRNPA1 overexpression. more...

(Submitter supplied) In the earliest step of spliceosome assembly, the two splice sites flanking an intron are brought into proximity by U1 snRNP and U2AF. The mechanism that facilitates this intron looping is poorly understood. Using a CRISPR interference-based approach to halt RNA polymerase II transcription in the middle of introns, we discovered that the 5 splice site base pairs with a U1 snRNA that is tethered to RNA polymerase II during intron synthesis. more...

(Submitter supplied) Alternative splicing diversifies mRNA transcripts in human cells. While the spliceosome pairs exons with a high degree of accuracy, the rates of rare aberrant and non-canonical pre-mRNA splicing have not been evaluated at the nucleotide level to determine the quantity and identity of these events across splice junctions. Using ultra-deep sequencing the frequency of aberrant and non-canonical splicing events for three splice junctions flanking exon 7 of SMN1 were determined at single nucleotide resolution. more...
