A 335-kDa protein complex (approx.) deposited 20–24 nucleotides upstream of the splice junction (see Fig. E61). DExH/D proteins are instrumental in separating the RNA from the EJC protein complex. The complex includes SRm160 and RNPS1 coactivators of splicing and SRm160 enhances the processing of the 3′-end. Exon junction complexes (EJCs) are deposited on mRNAs during splicing and displaced by ribosomes during the pioneer round of translation. Nonsense-mediated mRNA decay (NMD) degrades EJC-bound mRNA, but the lack of suitable methodology has prevented the identification of other degradation pathways. Exon junction complex.

One of the best-studied examples is the exon junction complex (EJC), a multiprotein complex deposited primarily 24 nucleotides upstream of exon-exon junctions as a consequence of pre-mRNA splicing. The EJC maintains a stable, sequence-independent, hold on the mRNA until its removal during translation in the cytoplasm. The exon junction complex (EJC) consists of four core proteins: Magoh, RNA-binding motif 8A (Rbm8a, also known as Y14), eukaryotic initiation factor 4A3 (eIF4A3, also known as DDX48), and metastatic lymph node 51 (MLN51, also known as Casc3 or Barentsz), which are involved in the regulation of many processes occurring between gene transcription and protein translation. 2018-02-19 · During splicing, the exon junction complex (EJC) is deposited upstream of exon-exon boundaries.

However, the exact sequence of EJC assembly and the involved factors during splicing remain elusive.

HUGO Gene Nomenclature Committee (HGNC) gene group report for Exon junction complex, containing 5 genes within the group. The exon junction complex (EJC) participates in the regulation of many post- transcriptional steps of gene expression. EJCs are deposited on messenger RNAs The exon junction complex core protein Y14 is required for nonsense-mediated mRNA decay (NMD) and promotes translation. Moreover, Y14 binds the cap Here, we identified Mago Nashi (Mago) and Y14 core Exon Junction Complex ( EJC) proteins, as well as the Srp54 splicing factor, as modifiers of Hh pathway The exon junction complex (EJC) is a protein complex that assembles near exon- exon junctions of mRNAs as a result of splicing.

role for the multiprotein exon–exon junction complex (EJC) in coordinating these mRNA-surveillance mechanisms1–3. When an intron is spliced out of a pre-mRNA molecule, the EJC is deposited approximately 20 nucleotides upstream of the resulting exon–exon junction, establishing a positional marker on the mRNA. Inside the nucleus, the EJC

24 nucleotides upstream of exon–exon junctions as a consequence of pre-mRNA. HUGO Gene Nomenclature Committee (HGNC) gene group report for Exon junction complex, containing 5 genes within the group. The exon junction complex (EJC) participates in the regulation of many post- transcriptional steps of gene expression.

An imbalance in EJC dosage alters mouse neural stem cell (mNSC) division and is linked to This nucleus-cytoplasm connection is currently explained by the so-called exon junction complex, which is thought to attach to mature mRNAs at the junction between two exons and stay bound until the mRNA moves to the cytoplasm. The exon junction complex (EJC) is deposited onto mRNAs following splicing and adopts a unique structure, which can both stably bind to mRNAs and function as an anchor for diverse processing The exon junction core complex consists of four proteins that form a dynamic binding platform for a variety of peripheral factors involved in mRNA metabolism. In the complex, mRNA binding is mediated by the DEAD-box protein eIF4AIII, and inhibition of its ATPase activity forms the mechanistic basis for the long-term stability of the complex. One of the best‐studied examples is the exon junction complex (EJC), a multiprotein complex deposited primarily 24 nucleotides upstream of exon–exon junctions as a consequence of pre‐mRNA splicing. The EJC maintains a stable, sequence‐independent, hold on the mRNA until its removal during translation in the cytoplasm. An exon junction complex (EJC) is a protein complex which forms on a pre-messenger RNA strand at the junction of two exons which have been joined together during RNA splicing. The EJC has major influences on translation, surveillance and localization of the spliced mRNA.

The proteins in the EJC have roles in mRNA export, localization and surveillance. The Exon Junction Complex keeps the amount of Dishevelled protein in check via an interaction with another protein referred to as Discs large. Further experiments indicated that Discs large binds to and protects Dishevelled from being degraded inside the cell.

During splicing, the exon junction complex (EJC) is deposited upstream of exon-exon boundaries. The EJC and its peripheral bound proteins play an essential role in mediating mRNA export, translation and turnover. However, the exact sequence of EJC assembly and the involved factors during splicing remain elusive. Recently published structures of the human C* spliceosome clarified the position

2017-07-07 2006-02-15 Nonsense-mediated decay has been observed with mRNAs that do not have an exon junction complex (EJC) downstream of the termination codon (reviewed in Isken and Maquat 2007, Chang et al. 2007, Behm-Ansmant et al. 2007, Rebbapragada and Lykke-Andersen 2009, Nicholson et al. 2010).
