CC   -!- FUNCTION: Core component of the splicing-dependent multiprotein exon
CC       junction complex (EJC) deposited at splice junctions on mRNAs. The EJC
CC       is a dynamic structure consisting of core proteins and several
CC       peripheral nuclear and cytoplasmic associated factors that join the
CC       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) (By similarity).
CC       {ECO:0000250|UniProtKB:P61326}.
CC   -!- SUBUNIT: Part of the EJC core complex that contains CASC3, EIF4A3,
CC       MAGOH and RBM8A. {ECO:0000250|UniProtKB:P61326}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:P61326}. Nucleus
CC       speckle {ECO:0000250|UniProtKB:P61326}. Cytoplasm
CC       {ECO:0000250|UniProtKB:P61326}. Note=Travels to the cytoplasm as part
CC       of the exon junction complex (EJC) bound to mRNA.
CC       {ECO:0000250|UniProtKB:P61326}.
CC   -!- SIMILARITY: Belongs to the mago nashi family. {ECO:0000305}.
