Project description:RBM5, a regulator of alternative splicing of apoptotic genes, and its close homologues, RBM6 and RBM10, are RNA binding proteins frequently deleted or mutated in lung cancer. We report that RBM5/6 and RBM10 antagonistically regulate the proliferative capacity of cancer cells and display distinct positional effects in alternative splicing regulation. We identify the Notch pathway regulator NUMB as a key target of these factors in the control of cell proliferation. NUMB alternative splicing, which is frequently altered in lung cancer, can regulate colony and xenograft tumor formation and its modulation recapitulates or antagonizes the effects of RBM5, 6 and 10 in cell colony formation. RBM10 mutations identified in lung cancer cells disrupt NUMB splicing regulation to promote cell growth. Our results reveal a key genetic circuit in the control of cancer cell proliferation. CLIP-Seq analysis of RBM5, RBM6 and RBM10, with 2 biological replicates and one non-specific control for each protein.

RNA from 3 biological replicates of knockdowns of RBM5, 6 and 10 and a control set were used. Changes between the control and knockdowns were measured based on using a splice-junction array (Affymetrix HJAY).

Project description:RBM5 and RBM10 are RNA-binding proteins and splicing regulators. These two proteins are putative paralogs in mammalian cells, sharing common domain organization and extensive protein sequence similarity, but their RNA-binding preferences differ. We developed a sensitive system to identify splicing events regulated by RBM5 and/or RBM10, deleting all RBM5 alleles in 293Flp-In cells, and reducing the expression of RBM10, which is partially rescued by activation of a cryptic exon (CE) in one of the RBM10 alleles. RBM5 or RBM10 transgenes were then introduced in these RBM5-null, RBM10 mutant cells (RBM5-/-;RBM10-/CE), allowing controlled protein expression, induced with Doxycycline. Using this system we identify thousands of RBM5 and RBM10-regulated cassette exons, and note a substantial overlap between the two sets.

Project description:Mutations in the RNA-binding protein, RBM10, result in a human syndromic form of cleft palate, termed TARP syndrome. A role for RBM10 in alternative splicing regulation has been previously demonstrated in human cell lines. To uncover the cellular functions of RBM10 in a cell line that is relevant to the phenotype observed in TARP syndrome, we used iCLIP to identify its endogenous RNA targets in a mouse embryonic mandibular cell line. We observed that RBM10 binds to pre-mRNAs with significant enrichment in intronic regions, in agreement with a role for this protein in pre-mRNA splicing. In addition to protein-coding transcripts, RBM10 also binds to a variety of cellular RNAs, including non-coding RNAs, such as spliceosomal small nuclear RNAs, U2 and U12. RNA-seq was used to investigate changes in gene expression and alternative splicing in RBM10 KO mouse mandibular cells and also in mouse ES cells. We uncovered a role for RBM10 in the regulation of alternative splicing of common transcripts in both cell lines but also identified cell-type specific events. Importantly, those pre-mRNAs that display changes in alternative splicing also contain RBM10 iCLIP tags, suggesting a direct role of RBM10 in these events. Finally, we show that depletion of RBM10 in mouse ES cells leads to proliferation defects and to gross alterations in their differentiation potential. These results demonstrate a role for RBM10 in the regulation of alternative splicing in two cell models of mouse early development and suggests that mutations in RBM10 could lead to splicing changes that affect normal palate development and cause human disease.

Project description:RBM10 is an RNA-binding protein that plays an essential role in development and is frequently mutated in the context of human disease. RBM10 recognizes a diverse set of RNA motifs in introns and exons and regulates alternative splicing. However, the molecular mechanisms underlying this seemingly relaxed sequence specificity are not understood and functional studies have focused on 3’ intronic sites only. Here we dissect the RNA code recognized by RBM10 and relate it to the splicing regulatory function of this protein. We show that a two-domain RRM1-ZnF unit recognises a GGA-centred motif enriched in RBM10 exonic sites with high affinity and specificity and test that the interaction with these exonic sequences promotes exon skipping. Importantly, a second RRM domain (RRM2) of RBM10 recognises a C-rich sequence, which explains its known interaction with the intronic 3’ site of NUMB exon 9 contributing to regulation of the Notch pathway in cancer. Together, these findings explain RBM10’s broad RNA specificity and suggest that RBM10 functions as a splicing regulator using two RNA-binding units with different specificities to promote exon skipping.

Project description:RNA Binding Motif 5 (RBM5) is a nuclear splicing factor. Prior studies show that RBM5 overexpression in cancer cells alters gene splicing, gene expression, and induces cell death and/or growth arrest. The role of RBM5 in primary neurons is unknown, and its potential mRNA targets have not been identified. Using lentivirus based approaches we tested if RBM5 knockdown (i.e. by shRNA) or RBM5 overexpression (DDK-tagged rat open reading frame) alters whole genome expression in primary rat cortical neurons. We used microarrays to examine genes that are up-regulated vs. down-regulation in cortical neurons after RBM5 knockdown vs. overexpression.
