Predicted to enable RNA binding activity. Predicted to be involved in mRNA splicing, via spliceosome and nuclear-transcribed mRNA catabolic process, nonsense-mediated decay. Predicted to act upstream of or within mRNA processing and mRNA transport. Predicted to be located in neuronal cell body and nucleus. Predicted to be part of exon-exon junction complex and spliceosomal complex. Orthologous to human MAGOHB (mago homolog B, exon junction complex subunit).
