Predicted to enable C5-methylcytidine-containing RNA binding activity; mRNA binding activity; and single-stranded DNA binding activity. Predicted to be involved in several processes, including mRNA export from nucleus; regulation of nucleobase-containing compound metabolic process; and viral mRNA export from host cell nucleus. Predicted to be located in cytoplasm and nuclear speck. Predicted to be part of catalytic step 2 spliceosome and transcription export complex. Predicted to be active in nucleus. Predicted to colocalize with chromosome, telomeric region. Orthologous to human ALYREF (Aly/REF export factor). [provided by Alliance of Genome Resources, Apr 2022]
