Predicted to enable RNA binding activity. Predicted to be involved in RNA splicing; nuclear-transcribed mRNA catabolic process, nonsense-mediated decay; and regulation of alternative mRNA splicing, via spliceosome. Predicted to be located in nucleus. Predicted to be part of catalytic step 2 spliceosome and exon-exon junction complex. Orthologous to human MAGOH (mago homolog, exon junction complex subunit).
