It is possible but not yet demonstrated that all components of the SURF complex (SMG1, UPF1, eRF1, eRF3) are assembled on an mRNA without an exon junction complex and that UPF1 is phosphorylated by SMG1. 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. 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.

2017-11-09 Exon junction complex. Protein complex which forms on a pre-messenger RNA strand at the junction of two exons which have been joined together during RNA splicing. Wikipedia. RNA splicing. Form of RNA processing in which a newly made precursor messenger RNA transcript is transformed into a mature messenger RNA (mRNA). 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 2016-08-18 2018-12-01 The Hierarchy of Exon-Junction Complex Assembly by the Spliceosome Explains Key Features of Mammalian Nonsense-Mediated mRNA Decay Niels H.

Gehring1,* The exon junction complex (EJC) is an RNA-binding protein complex that is assembled anddepositedontomRNAsduringsplicing.TheEJCcomprisesfour core components that bind to not only canonical sites upstream of exon–exon junctions, manner. 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 product of this gene is a core component of the exon junction complex (EJC), a protein complex that is deposited on spliced mRNAs at exon-exon junctions and functions in nonsense-mediated mRNA decay (NMD). The encoded protein binds RNA and interacts with two other EJC core components.

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 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.
