Protein arginine methyltransferase AtPRMT5 is involved in pre-mRNA splicing in Arabidopsis thaliana

ABSTRACT: In this study, we analyzed the Arabidopsis homologue of PRMT5, AtPRMT5M-bM-^@M-^Ys function in RNA processing. RNA-seq analyses revealed that AtPRMT5 is involved in a subset of pre-mRNA splicing. Several RNA processing factors involved in regulating flowering time were validated that the corresponding intron retention surely exists in atprmt5 mutants. AtSm proteins can also be methylated by AtPRMT5 in vitro and in vivo, which may be the reasons for the pre-mRNA splicing defects in atprmt5.

Protein arginine methylation, one of the most abundant and important posttranslational modifications, is involved in a multitude of biological processes in eukaryotes, such as transcriptional regulation and RNA processing. Symmetric arginine dimethylation is required for snRNP biogenesis and is assumed to be essential for pre-mRNA splicing; however, except for in vitro evidence, whether it affects splicing in vivo remains elusive. Mutation in an Arabidopsis symmetric arginine dimethyltransferase ...[more]

SKIP Is a Component of the Spliceosome Linking Alternative Splicing and the Circadian Clock in Arabidopsis

Project description:Circadian clocks generate endogenous rhythms in most organisms from cyanobacteria to humans and facilitate entrainment to environmental diurnal cycles, thus conferring a fitness advantage. Both transcriptional and posttranslational mechanisms are prominent in the basic network architecture of circadian systems. Posttranscriptional regulation, including mRNA processing, is emerging as a critical step for the clock function. However, little is known about the molecular mechanisms linking RNA metabolism to the circadian clock network. Here we report that a conserved SNW/SKIP domain protein, SKIP, a splicing factor and component of the spliceosome, is involved in the posttranscriptional regulation of circadian clock genes in Arabidopsis. Mutation in SKIP lengthens the circadian period in a temperature sensitive manner, affects light input and the sensitivity of light resetting to the clock. SKIP physically interacts with the spliceosomal splicing factor SR45 and associates with the pre-mRNA of clock genes, such as PRR7 and PRR9, and is necessary for the regulation of their alternative splicing and mRNA maturation. Genome-wide investigations reveal that SKIP functions in regulating alternative splicing of many genes, presumably through modulating recognition or cleavage of 5' and 3' splicing site. Our study addresses a fundamental question on how the mRNA splicing machinery contributes to circadian clock functions at a posttranscriptional level. Our findings revealed that AtSKIP is a splicing factor and a component of spliceosome. To further investigate effects of mutation in SKIP on the genome-wide changes of alternative splicing, we performed ultra-highthroughput RNA sequencing, using 10-day old seedlings. Two biological replicates for both wild type (Col-0) and skip-2 were designed.

RNA-Seq of control and ELL2-depleted MPC11 plasmacytoma cell lines

Project description:We report RNA-Seq data from MPC11 plasmacytoma cell lines transduced with either control hairpins (shGFP) or hairpins targeting the transcriptional elongation factor ELL2. ELL2 has been identified as regulating the alternative splicing and polyadenylation of immunoglobulin pre-mRNA, and is highly expressed by plasma cells but not other B cells. Notably, ELL2 drives the accumulation of transcripts encoding secreted immunoglobulin at the expense of membrane-associated transcripts. This study sought to examine the impact of ELL2 on mRNA processing at the transcriptome level, and found that ELL2 controls the alternative processing of 12% of annotated transcripts in MPC11 cells.

Identification of human mRNA processing complexes bound to histone H2A.2 3’ untranslated region

Project description:Processing of 3’ untranslated region (3’-UTR) of precursor messenger RNAs (pre-mRNA) is a fundamental step in mRNA maturation, where the mRNA transcript is cleaved at a specific site, located downstream the open reading frame of the encoded gene. The position of the cleavage site is determined by cis-acting RNA sequence elements, which are recognized with high specificity by large 3’ end processing multiprotein complexes. Two main categories of metazoan 3’ pre-mRNA processing have been identified so far, describing elaboration of either canonical mRNAs – occurring during all phases of the cell cycle and containing a characteristic Poly-Adenylation Signal (PAS) element – or histone mRNAs – prevalently occurring during the S phase and containing a Histone Downstream Element (HDE). In this work, we isolate both human endogenous canonical and histone 3’ pre-mRNA processing complexes from human nuclear extracts by using a pre-mRNA containing the 3’UTR sequence of replication-dependent histone H2A.2. This H2A.2 pre-mRNA (H2A_4m), containing both an HDE sequence and a PAS element in a native overlaid position, was modified with a 5’ photocleavable biotin tag, and with modification of few bases to allow complex assembly and purification by affinity chromatography on streptavidin-agarose beads, elution by UV irradiation and subsequent mass spectrometric identification of bound 3’ mRNA processing factors.

SnapShot-Seq: a method for extracting genome-wide, in vivo mRNA dynamics from a single total RNA sample

Project description:mRNA synthesis, processing, and destruction involve a complex series of molecular steps that are incompletely understood.Â Because the RNA intermediates in each of these steps have finite lifetimes, extensive mechanistic and dynamical information is encoded in total cellular RNA. Here we report the development of SnapShot-Seq, a set of computational methods that allow the determination of in vivo rates of pre-mRNA synthesis, splicing, intron degradation, and mRNA decay from a single RNA-Seq snapshot of total cellular RNA. SnapShot-Seq can detect in vivo changes in the rates of specific steps of splicing, and it provides genome-wide estimates of pre-mRNA synthesis rates comparable to those obtained via labeling of newly synthesized RNA. We used SnapShot-Seq to investigate the origins of the intrinsic bimodality of metazoan gene expression levels, and our results suggest that this bimodality is partly due to spillover of transcriptional activation from highly expressed genes to their poorly expressed neighbors. SnapShot-Seq dramatically expands the information obtainable from a standard RNA-Seq experiment. These data are total RNA-Seq data, from RNA sequencing of rRNA-depleted total cellular RNA -- except the LCL 4SU data, which derive from 4SU-labeled RNA. Please see the associated paper for more details.

Proteomics identifies ubiquitin-proteasome targets and new roles for chromatin-remodelling in the Arabidopsis response to phosphate starvation

Project description:In order to identify new regulators of the phosphate (Pi) starvation signaling pathway in plants, we analyzed variation in the abundance of nuclear-enriched nuclear proteins isolated from Arabidopsis roots that depends on Pi supply. We used 2-D Fluorescence Difference Gel Electrophoresis and MALDI-TOF/TOF techniques for nuclear proteome separation, visualization and relative protein abundance quantification and identification. Pi-controlled proteins identified in our analysis included components of the chromatin remodeling, DNA replication, and mRNA splicing machineries. In addition, by combining Pi starvation conditions with proteasome inhibitor treatments, we characterized the role of the ubiquitin- (Ub)-proteasome system (UPS), a major mechanism for targeted protein degradation in eukaryotes, in the control of the stability of Pi-responsive proteins. Among Pi-responsive proteins, the histone chaperone NAP1;2 was selected for further characterization, and was shown to display differential nucleo-cytoplasmic accumulation in response to Pi deprivation. We also found that mutants affecting three members of the NAP1 family accumulate lower Pi levels and display reduced expression of Pi starvation-inducible genes, reflecting a regulatory role for these chromatin-remodelling proteins in Pi homeostasis.

Arabidopsis SME interactome reveals spliceosome components

Project description:Alternative splicing (AS) can produce multiple transcripts with different exon-intron structures from a single pre-mRNA. Pre-mRNA splicing is catalyzed by a dynamic macromolecular ribonucleoprotein (RNP) complex termed the spliceosome. The spliceosome consists of several small nuclear ribonucleoproteins (snRNPs) that bind uridine-rich small nuclear RNA (snRNA). In U1, U2, U4 and U5 snRNPs, snRNA interacts with the conserved Smith antigen (Sm) proteins via a bipartite Sm sequence motif. In eukaryotes, seven Sm proteins (B, D1/2/3, E, F and G) form a heptameric ring-shaped complex surrounding the snRNA. Here, we performed a tandem affinity purification using SMEB as a bait in Arabidopsis cell suspension cultures. At least 45 known/hypothesized and potential novel spliceosome components were identified in Arabidopsis.

The competition between splicing and 3′ processing shapes the human transcriptome

Project description:Eukaryotic pre-mRNA processing steps, including splicing and 3′ processing, are tightly coordinated, but the underlying mechanisms remain poorly understood. Previous studies proposed that the splicing factor U1 snRNP inhibits 3′ processing at intronic polyadenylation (IPA) sites through a splicing-independent mechanism, called telescripting. However, we found that global or gene-specific perturbation of splicing by targeting multiple splicing factors, including U1 snRNP, U2 snRNP, U2AF, and SF3b led to activation of 3′ processing at IPA sites. Inhibiting different splicing factors activated overlapping and distinct IPA sites and such specificity was determined, at least in part, by alterations in RNA polymerase II elongation and termination. Conversely, we showed that blocking pre-mRNA 3′ processing promoted splicing globally. These results strongly suggest that splicing and 3′ processing are competing processes that shape the transcriptome. Finally, as splicing inhibition-induced shifts to IPA site usage can lead to gene inactivation, including tumor suppressor genes, the use of general splicing inhibitors to treat human diseases may pose a significant risk.

Dysregulated RNA polyadenylation contributes to metabolic impairment in non-alcoholic fatty liver disease

Project description:Pre-mRNA processing is an essential mechanism for the generation of mature mRNA and the regulation of gene expression in eukaryotic cells. While defects in pre-mRNA processing have been implicated in a number of diseases their involvement in metabolic pathologies is still unclear. Here we show that both alternative splicing and alternative polyadenylation, two major steps in pre-mRNA processing, are significantly altered in non-alcoholic fatty liver disease (NAFLD). Moreover, we find that Serine and Arginine Rich Splicing Factor 10 (SRSF10) binding is enriched adjacent to consensus polyadenylation motifs and its expression is significantly decreased in NAFLD, suggesting a role mediating pre-mRNA dysregulation in this condition. Consistently, inactivation of SRSF10 in mouse and human hepatocytes in vitro, and in mouse liver in vivo, was found to dysregulate polyadenylation of key metabolic genes such as peroxisome proliferatoractivated receptor alpha (PPARA) and exacerbate diet-induced metabolic dysfunction. Collectively our work implicates dysregulated pre-mRNA polyadenylation in obesity-induced liver disease and uncovers a novel role for SRSF10 in this process.
