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.

This study demonstrates that cryptic exon retention and exon skipping are new VHL alterations and reveals a novel complex splicing regulation of the VHL gene. These findings open new avenues for diagnosis and research regarding the VHL-related hypoxia-signaling pathway. 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). However, it subsequently became clear that NMD can occur in the absence of an EJC (Bühler et al., 2006; exon(-exon) junction:エキソン-エキソン接合部 splicing でintron が除かれた後、exon とexon が結合した接合部。 exon-junction complex:エキソン接合部複合体 splicing でexon が結合された最、exon-exon junction*の上流20~24 nt付近に形成される蛋 白質複合体。 The exon-exon junction complex comprises proteins that bind mRNAs that are produced by splicing in the nucleus.

Its main role is to The exon junction complex (EJC) is a multi-protein complex and universal component of spliced messenger ribonucleoproteins (mRNPs) in metazoans that carries out important functions in mRNA metabolism (reviewed in [1–3]). EJCs consist of three invariable core factors (Figure1A) and many The exon junction complex regulates the cell polarity determinant Discs large 1, which acts independently from its role in cell polarity to protect Dishevelled protein from lysosomal degradation in Wingless/Wnt signaling. Here we find that the nuclear exon junction complex (pre-EJC) is a critical and conserved regulator of this process.

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.

Exon junction complex

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). The exon junction complex: structural insights into a faithful companion of mammalian mRNPs. Gerbracht JV (1), Gehring NH (2). Previous studies focused on cryptic RS-exons, and now we find that the exon junction complex (EJC) represses RS of hundreds of annotated, mainly constitutive RS-exons.

The EJC is deposited on nascent mRNAs during splicing in a sequence-independent manner 20–24 nucleotides (nts) upstream of exon–exon junctions [4]. The y-axis represents the number of exon/exon junctions detected. The total number of known exon/exon junctions are approximately 163,000, RefSeq (hg18). that can span a putative exon/exon junction, thus increasing the chances of detecting exon/exon junctions. However, the presence of an exon/exon junction is inferred and 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 exon junction complex (EJC) is an essential constituent and regulator of spliced messenger ribonucleoprotein particles (mRNPs) in metazoans.

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 2016-11-23 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. 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. Exon Junction Complex (EJC) refers to a complex of at least six proteins that is deposited upstream of exon-exon junctions on RNAs undergoing splicing.
