ID:RBM8A_HUMAN DESCRIPTION: RecName: Full=RNA-binding protein 8A; AltName: Full=Binder of OVCA1-1; Short=BOV-1; AltName: Full=RNA-binding motif protein 8A; AltName: Full=RNA-binding protein Y14; AltName: Full=Ribonucleoprotein RBM8A; 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). 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. Remains associated with mRNAs in the cytoplasm until the mRNAs engage the translation machinery. Its removal from cytoplasmic mRNAs requires translation initiation from EJC-bearing spliced mRNAs. Associates preferentially with mRNAs produced by splicing. Does not interact with pre-mRNAs, introns, or mRNAs produced from intronless cDNAs. Associates with both nuclear mRNAs and newly exported cytoplasmic mRNAs. Complex with MAGOH is a component of the nonsense mediated decay (NMD) pathway. SUBUNIT: Heterodimer with MAGOH. Part of the exon junction complex (EJC) core complex that contains CASC3, EIF4A3, MAGOH and RBM8A. Found in a mRNA splicing-dependent EJC, at least composed of ACIN1, CASC3, DEK, EIF4A3, MAGOH, NCBP1, NCBP2, PNN, NXF1, RBM8A, UPF2, UPF3A, UPF3B, RNPS1, SAP18, SRRM1 and ALYREF/THOC4. Found in a post-splicing complex with NXF1, RBM8A, UPF1, UPF2, UPF3A, UPF3B and RNPS1. Interacts with BAT1, MAGOH, OVCA1, UPF3B, RNPS1, SRRM1 and ALYREF/THOC4. Identified in the spliceosome C complex. Interacts with WIBG/PYM; the interaction is direct and leads to dissociate the EJC from spliced mRNAs. Associates with polysomes. INTERACTION: P38919:EIF4A3; NbExp=8; IntAct=EBI-447231, EBI-299104; P61326:MAGOH; NbExp=19; IntAct=EBI-447231, EBI-299134; Q9H1J1:UPF3A; NbExp=4; IntAct=EBI-447231, EBI-521530; Q9BZI7:UPF3B; NbExp=8; IntAct=EBI-447231, EBI-372780; SUBCELLULAR LOCATION: Nucleus. Nucleus speckle. Cytoplasm. Note=Nucleocytoplasmic shuttling protein. 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. TISSUE SPECIFICITY: Ubiquitous. SIMILARITY: Belongs to the RBM8A family. SIMILARITY: Contains 1 RRM (RNA recognition motif) domain. SEQUENCE CAUTION: Sequence=AAG14951.1; Type=Erroneous initiation; Sequence=AAG16782.1; Type=Erroneous initiation; Sequence=AAG16782.1; Type=Miscellaneous discrepancy; Note=Chimeric cDNA. A chimeric cDNA originating from chromosomes 1 and 5;
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
