General annotation (Comments)
| Function | Component of a splicing-dependent multiprotein exon junction complex (EJC) deposited at splice junction on mRNAs. The EJC is a dynamic structure consisting of a few core proteins and several more peripheral nuclear and cytoplasmic associated factors that join the complex only transiently either during EJC assembly or during subsequent mRNA metabolism. Core components of the EJC, that remains bound to spliced mRNAs throughout all stages of mRNA metabolism, functions to mark the position of the exon-exon junction in the mature mRNA and thereby influences downstream processes of gene expression including mRNA splicing, nuclear mRNA export, subcellular mRNA localization, translation efficiency and nonsense-mediated mRNA decay (NMD). Remains associated with the mRNA after its export to the cytoplasm and require translation of the mRNA for removal. The heterodimer MAGOH-RBM8A interacts with PYM that function to enhance the translation of EJC-bearing spliced mRNAs by recruiting them to the ribosomal 48S preinitiation complex. Ref.9 Ref.11 |
| Subunit structure | Heterodimer with RBM8A. Part of the EJC core complex that contains CASC3, EIF4A3, MAGOH and RBM8A. Found in a mRNA splicing-dependent exon junction complex (EJC), at least composed of ACIN1, CASC3, EIF4A3, MAGOH, NCBP1, NCBP2, PNN, RBM8A, RNPS1, SRRM1, NXF1, SAP18, UPF3B, UPF2 and ALYREF/THOC4. Interacts with WIBG/PYM; the interaction is direct and leads to dissociate the EJC from spliced mRNAs. Identified in the spliceosome C complex. Ref.7 Ref.8 Ref.9 Ref.10 Ref.12 Ref.13 Ref.14 Ref.15 |
| Subcellular location | Nucleus. Nucleus speckle. Cytoplasm. Note: Detected in granule-like structures in the dendroplasm By similarity. Travels to the cytoplasm as part of the exon junction complex (EJC) bound to mRNA. Colocalizes with the core EJC, ALYREF/THOC4, NXF1 and UAP56 in the nucleus and nuclear speckles. Ref.16 |
| Tissue specificity | Ubiquitous. |
| Sequence similarities | Belongs to the mago nashi family. |
