The exon junction complex (EJC) is an abundant messenger ribonucleoprotein (mRNP) component that is assembled during splicing and binds to mRNAs upstream of exon-exon junctions. EJCs accompany the mRNA during its entire life in the nucleus and the cytoplasm and communicate the information about the splicing process and the position of introns.

The exon junction complex (EJC) is an essential constituent and regulator of spliced messenger ribonucleoprotein particles (mRNPs) in metazoans. As a core component of the EJC, CASC3 was described to be pivotal for EJC-dependent nuclear and cytoplasmic processes. 2017-11-09 · Export of mRNPs is enhanced by evolutionarily conserved multiprotein transcription-export complex (TREX) that is deposited on the pre-mRNA near the 5′-end cap . Also facilitating mRNP export is the exon-exon junction complex (EJC) that shares two proteins, Aly/REF and UAP56, with the TREX.

RNA. 10 (2 The exon junction complex (EJC) is a mainstay of spliced mRNPs in mammalian cells. Mabin et al. discovered that the EJC undergoes a switch in composition from RNPS1-containing complex to CASC3-containing complex. This compositional switch changes higher-order EJC and mRNP structure and specifies two distinct phases of EJC-dependent NMD. Brogna et al., 2016). Initially, the presence of an exon junction complex (EJC) downstream of a termination codon was thought to be essential to identify that termination codon as premature (Maquat, 2004).

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

An exon– exon junction complex (EJC) of proteins deposited ≈20- to 24- nucleotides upstream of exon–exon junctions during pre-mRNA splicing is considered to be a primary determinant of NMD in mammalian cells (Le Hir et al., 2000, 2001). 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.
