CC -!- FUNCTION: Required for pre-mRNA splicing as component of the
CC spliceosome (By similarity). Core component of the splicing-dependent
CC multiprotein exon junction complex (EJC) deposited at splice junctions
CC on mRNAs. The EJC is a dynamic structure consisting of core proteins
CC and several peripheral nuclear and cytoplasmic associated factors that
CC join the complex only transiently either during EJC assembly or during
CC subsequent mRNA metabolism. The EJC marks the position of the exon-exon
CC junction in the mature mRNA for the gene expression machinery and the
CC core components remain bound to spliced mRNAs throughout all stages of
CC mRNA metabolism thereby influencing downstream processes including
CC nuclear mRNA export, subcellular mRNA localization, translation
CC efficiency and nonsense-mediated mRNA decay (NMD). Its removal from
CC cytoplasmic mRNAs requires translation initiation from EJC-bearing
CC spliced mRNAs. Associates preferentially with mRNAs produced by
CC splicing. Does not interact with pre-mRNAs, introns, or mRNAs produced
CC from intronless cDNAs. Associates with both nuclear mRNAs and newly
CC exported cytoplasmic mRNAs (By similarity).
CC {ECO:0000250|UniProtKB:Q9Y5S9}.
CC -!- SUBUNIT: Heterodimer with either MAGOH or MAGOHB. Part of the mRNA
CC splicing-dependent exon junction complex (EJC) complex; the core
CC complex contains CASC3, EIF4A3, MAGOH or MAGOHB, and RBM8A. Interacts
CC with PYM1; the interaction is direct and dissociates the EJC from
CC spliced mRNAs. Part of a complex that contains the EJC core components
CC CASC3, EIF4A3, MAGOH and RBM8A plus proteins involved in nonsense-
CC mediated mRNA decay, such as UPF1, UPF2, UPF3A and UPF3B. Found in a
CC post-splicing complex with NXF1, MAGOH, UPF1, UPF2, UPF3A, UPF3B and
CC RNPS1. Interacts with DDX39B, MAGOH, DPH1, UPF3B, RNPS1, SRRM1 and
CC ALYREF/THOC4. Interacts with IPO13; the interaction mediates the
CC nuclear import of the MAGOH-RBM8A heterodimer. Identified in the
CC spliceosome C complex. Associates with polysomes.
CC {ECO:0000250|UniProtKB:Q9Y5S9}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000269|PubMed:16275927}. Nucleus
CC speckle {ECO:0000269|PubMed:16275927}. Cytoplasm
CC {ECO:0000269|PubMed:16275927}. Note=Nucleocytoplasmic shuttling
CC protein. Travels to the cytoplasm as part of the exon junction complex
CC (EJC) bound to mRNA. Colocalizes with the core EJC, ALYREF/THOC4, NXF1
CC and UAP56 in the nucleus and nuclear speckles.
CC {ECO:0000250|UniProtKB:Q9Y5S9}.
CC -!- SIMILARITY: Belongs to the RBM8A family. {ECO:0000305}.
