The EJC is a dynamic structure consisting of core proteins and several peripheral nuclear and cytoplasmic associated factors that join the complex only transiently either during EJC assembly or during subsequent mRNA metabolism. The EJC marks the position of the exon-exon junction in the mature mRNA for the gene expression machinery and the core components remain bound to spliced mRNAs throughout all stages of mRNA metabolism thereby influencing downstream processes including nuclear mRNA export, subcellular mRNA localization, translation efficiency and nonsense-mediated mRNA decay (NMD). The MAGOH-RBM8A heterodimer inhibits the ATPase activity of EIF4A3, thereby trapping the ATP- bound EJC core onto spliced mRNA in a stable conformation. The MAGOH-RBM8A heterodimer interacts with the EJC key regulator PYM1 leading to EJC disassembly in the cytoplasm and translation enhancement of EJC-bearing spliced mRNAs by recruiting them to the ribosomal 48S preinitiation complex. Involved in the splicing modulation of BCL2L1/Bcl-X (and probably other apoptotic genes); specifically inhibits formation of proapoptotic isoforms such as Bcl-X(S); the function is different from the established EJC assembly. {ECO:0000269|PubMed:12730685, ECO:0000269|PubMed:16209946, ECO:0000269|PubMed:22203037}. |Mago nashi| |exon-exon junction complex| |regulation of alternative mRNA splicing, via spliceosome| |mRNA 3-end processing| |catalytic step 2 spliceosome| |regulation of mRNA splicing, via spliceosome| |mRNA-containing ribonucleoprotein complex export from nucleus| |mRNA export from nucleus| |nuclear-transcribed mRNA catabolic process, nonsense-mediated decay| |ribonucleoprotein complex export from nucleus| |ribonucleoprotein complex localization| |RNA export from nucleus| |RNA 3-end processing| |regulation of RNA splicing| |regulation of mRNA processing| |protein export from nucleus| |mRNA transport| |nuclear export| |RNA transport| |nucleic acid transport| |establishment of RNA localization| |nuclear-transcribed mRNA catabolic process| |RNA localization| |mRNA catabolic process| |nucleobase-containing compound transport| |RNA catabolic process| |protein-containing complex localization| |nucleocytoplasmic transport| |nuclear transport| |RNA splicing, via transesterification reactions with bulged adenosine as nucleophile| |mRNA splicing, via spliceosome| |RNA splicing, via transesterification reactions| |regulation of mRNA metabolic process| |regulation of translation| |nucleobase-containing compound catabolic process| |RNA splicing| |nuclear speck| |regulation of cellular amide metabolic process| |heterocycle catabolic process| |cellular nitrogen compound catabolic process| |aromatic compound catabolic process| |mRNA processing| |organic cyclic compound catabolic process| |posttranscriptional regulation of gene expression| |mRNA metabolic process| |RNA processing| |cellular macromolecule catabolic process| |intracellular protein transport| |macromolecule catabolic process| |RNA binding| |protein transport| |intracellular transport| |peptide transport| |amide transport| |cellular protein localization| |cellular macromolecule localization| |establishment of protein localization| |RNA metabolic process| |negative regulation of gene expression| |organic substance catabolic process| |cellular catabolic process| |establishment of localization in cell| |nitrogen compound transport| |gene expression| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp518|RK-33 8μM R08 exp518]]|-1.77| |[[:results:exp351|Dexamethasone 0.006μM R07 exp351]]|1.82| No correlation found to any other genes in chemogenomics.
