DESCRIPTION

Also known as RBM8A_DROME, tsu, Y14. Core component of the splicing-dependent multiprotein exon junction complex (EJC) deposited at splice junctions on mRNAs (PubMed:14973490, PubMed:24967911). Involved in exon definition of genes containing long introns, including the rolled/MAPK gene (PubMed:20946982, PubMed:20946983). The mago-tsu heterodimer interacts with the EJC key regulator Pym leading to EJC disassembly in the cytoplasm (PubMed:24967911). Has a role in oskar mRNA localization to the posterior pole of the developing oocyte (PubMed:11691839). Heterodimer (via RRM domain) with mago (PubMed:11691839, PubMed:12730685, PubMed:12704080). Part of the mRNA splicing-dependent exon junction complex (EJC) complex; the core complex contains btz/CASC3, eIF4AIII, mago and tsu/RBM8A (PubMed:14973490). Interacts with Pym (via N-terminus); the interaction is direct (PubMed:24967911, PubMed:14968132). Interacts with eIF4AIII (PubMed:14973490).
