(Submitter supplied) During gene expression, RNA export factors are mainly known for driving nucleocytoplasmic transport. While early studies suggested that the Exon Junction Complex (EJC) may provide a binding platform for them, subsequent work proposed that they are only recruited by the Cap-Binding Complex (CBC) to the 5’ end of RNAs, as part of the TREX complex. Using iCLIP, we show that the export receptor Nxf1 and two TREX subunits, Alyref and Chtop, are actually recruited to the whole mRNA co-transcriptionally via splicing but before 3’-end processing. more...

(Submitter supplied) Alternative polyadenylation (APA) produces mRNA isoforms with different 3’UTR lengths. Previous studied indicated that 3’ end processing and mRNA nuclear export are intertwined in gene regulation. Here, we show that mRNA export factors generally facilitate usage of distal cleavage and polyadenylation sites (PASs), leading to expression of long 3’UTR isoforms. By focusing on the export receptor NXF1, which exhibits the most potent effect on APA in this study, we reveal a number of gene features that impact NXF1-dependent APA, including 3’UTR size, gene size and AT content. more...

(Submitter supplied) We report that knockdown of EJC core proteins, eIF4A3, Y14, Magoh, causes a transcript-wide changes in alternative splicing, as well as some transcriptional changes. These changes are specific to EJC core proteins, and KD of UPF1 protein caused different sets of alterantive splicing changes. These changes are linked to the rate of transcription.

(Submitter supplied) The nuclear export pathway transports long RNAs produced in the nucleus to the cytoplasm. The core components of this pathway are thought to be required for export of virtually all polyadenylated RNAs. Here, we depleted different proteins that act in nuclear export in human cells, and quantified the transcriptome-wide consequences on RNA localization. Different genes exhibited substantially variable sensitivities, with depletion of NXF1 and TREX components causing some transcripts to become strongly retained in the nucleus while others were not affected. more...

(Submitter supplied) Our data suggest that all SR proteins contribute to mRNA export via NXF1. To identify endogenous export targets we depleted all seven SR proteins individually from P19 WT cells prepared cytoplasmic fractions. We sequenced the cytoplasmic fraction and as a control whole celll RNA from the identical sample.

(Submitter supplied) We used GFP-tagged SR proteins expressed at endogenous levels and iCLIP to identify and compare endogenous RNA targets of individual SR proteins, map the preferential sites of binding, compare binding pattern and binding motifs between family members and to NXF1 and quantify binding of SR proteins and NXF1 to spliced versus unspliced RNAs to study the role of SR proteins in mRNA export via NXF1.

(Submitter supplied) To eliminate the possibility that for a particular gene the increased RNA level is an effect of enhanced transcription. We carried out ChIP-seq for RNAPII to compare transcription of mRNAs and lncRNAs in control, hRRP40 and hMTR4 knockdown cells. Among 15000 RNAPII binding peaks identified in these samples, only less than 50 peaks was significantly increased in hRRP40 or hMTR4 knockdown cells.

(Submitter supplied) The exon junction complex (EJC) is a central effector of mRNAs fate, linking nuclear processing to mRNA transport, translation and surveillance. Little is known about its transcriptome-wide targets. We used high-throughput sequencing after crosslinking and immunoprecipitation (HITS-CLIP) in human cells to identify the binding sites of the DEAD-box helicase eIF4AIII, an EJC core component. CLIP reads form peaks mainly located in spliced mRNAs. more...

(Submitter supplied) N6-methyladenosine (m6A) is the most abundant internal modification of eukaryotic mRNA. This modification has previously been shown to alter the export kinetics for mRNAs though the molecular details surrounding this phenomenon remain poorly understood. Here we show that the m6A complex (WTAP, KIAA1429, METTL3/14) drives recruitment of the TREX mRNA export complex onto m6A modified mRNAs and this process is essential for the efficient export of certain mRNAs. more...

(Submitter supplied) Nuclear export of mRNA is an essential process for eukaryotic gene expression. TREX complex couples the gene expression from transcription and splicing to mRNA export. Sub2, a core component of TREX complex in yeast is diversified to two closely related RNA helicases, UAP56 and URH49 in human.UAP56 and URH49 are required for bulk poly (A)+ RNA export but their target genes are quite different. In conclusion, UAP56 and URH49 have a different function in vivo despite the highly similarity.
