Genome-wide Analysis Reveals SR Protein Cooperation and Competition in Regulated Splicing

Project description:SR proteins are well-characterized RNA binding proteins that promote exon inclusion by binding to exonic splicing enhancers (ESEs). However, it has been unclear whether regulatory rules deduced on model genes apply generally to activities of SR proteins in the cell. Here, we report global analyses of two prototypical SR proteins SRSF1 (SF2/ASF) and SRSF2 (SC35) using splicing-sensitive arrays and CLIP-seq on mouse embryo fibroblasts (MEFs). Unexpectedly, we find that these SR proteins promote both inclusion and skipping of exons in vivo, but their binding patterns do not explain such opposite responses. Further analyses reveal that loss of one SR protein is accompanied by coordinated loss or compensatory gain in the interaction of other SR proteins at the affected exons. Therefore, specific effects on regulated splicing by one SR protein actually depend on a complex set of relationships with multiple other SR proteins in mammalian genomes. SRSF1 and SRSF2 CLIP-seq

Global Regulation of Alternative RNA Splicing by the SR-Rich Protein RBM39

Project description:RBM39 is extensively involved in alternative splicing of RNA and helps regulate transcript levels. RBM39 may modulate alternative splicing similarly to U2AF65 by either directly binding to RNA or recruiting other splicing factors, such as U2AF65.

Son Maintains Accurate Splicing of Pre-mRNAs Encoding Chromatin Modifiers

Project description:Exon and expression analysis of HeLa cells after knockdown of SON Serine-arginine-rich (SR) proteins play a key role in alternative pre-mRNA splicing in eukaryotes. Our laboratory recently showed that a large SR protein called Son has unique repeat motifs that are essential for maintaining the subnuclear organization of pre-mRNA processing factors in nuclear speckles. Motif analysis of Son highlights putative RNA interaction domains that suggest a direct role for Son in pre-mRNA splicing. A genome-wide screen was performed to identify putative human transcription and splicing targets of Son.

The Nuclear-retained non-coding RNA MALAT1 regulates alternative splicing by modulating SR splicing factor phosphorylation

Project description:Alternative splicing (AS) of pre-mRNA is utilized by higher eukaryotes to achieve increased transcriptome and proteomic complexity. The serine/arginine (SR) splicing factors regulate tissue- or cell type-specific AS in a concentration and phosphorylation dependent manner. However, the mechanisms that modulate the cellular levels of active SR proteins remain to be elucidated. In the present study, we provide evidence for a role for the long nuclear-retained regulatory RNA (nrRNA), MALAT1 in AS regulation. MALAT1 interacts with SR proteins and influences the distribution of these and other splicing factors in nuclear speckle domains. Depletion of MALAT1 changes AS of endogenous pre-mRNAs, similar to what was observed upon overexpression of SR proteins. Furthermore, MALAT1 regulates cellular levels of phosphorylated forms of SR proteins. Taken together, our results suggest that MALAT1 regulates AS by modulating the levels of active SR proteins. Our results further highlight a novel role for a nrRNA in the regulation of gene expression. Malat1 Antisense and control knockdowns evaluated on a microarray platform to profile alternative splicing levels for 5782 cassette-type alternative exons.

RNA-Seq of 293T cells depleted of U2AF-related proteins

Project description:Characterization of RNA processing events dependent on U2AF-related proteins PUF60 and RBM39. PUF60 (poly-U-binding factor 60 kDa, also known as FIR, Hfp or Ro-bp1) is a splicing factor homologous to the 65 kD subunit of the auxiliary factor of U2 small nuclear ribonucleoprotein (U2AF65). PUF60 has two central RNA recognition motifs and a C-terminal U2AF homology motif (UHM), but lacks the N terminal arginine/serine-rich (RS) and UHM ligand motif (ULM) domains present in U2AF65. PUF60 activity, in conjunction with U2AF, facilitates the association of U2 snRNP with the pre-mRNA. PUF60 and U2AF65 can bind SF3b155 ULMs simultaneously and noncompetitively. RBM39 (also known as CAPERα, HCC1, FSAP59 or RNPC2) is an RNA processing factor and a hormone-dependent transcriptional coactivator. RBM39 domain structure is similar to PUF60, except for the extra N-terminal RS domain with unknown function. To understand function of the two proteins on a genome-wide scale, each protein was individually depleted from human embryonic kidney cell line 293 using RNAi to systematically characterize the PUF60- and RBM39-dependent exon usage.
