Predicted to enable RNA binding activity and ribosome binding activity. Predicted to be involved in exon-exon junction complex disassembly; nuclear-transcribed mRNA catabolic process, nonsense-mediated decay; and positive regulation of translation. Predicted to act upstream of or within regulation of translation. Predicted to be located in nucleolus and nucleoplasm. Predicted to be part of exon-exon junction complex. Predicted to be active in cytoplasm. Orthologous to human PYM1 (PYM homolog 1, exon junction complex associated factor).
