Enables RNA 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 act upstream of or within RNA splicing; mRNA processing; and mRNA transport. Predicted to be located in cytoplasm. Predicted to be part of catalytic step 2 spliceosome; exon-exon junction complex; and transcription export complex. Predicted to be active in nucleus. Predicted to colocalize with chromosome, telomeric region. Is expressed in several structures, including branchial arch; central nervous system; genitourinary system; hemolymphoid system gland; and sensory organ. Orthologous to human ALYREF (Aly/REF export factor). [provided by Alliance of Genome Resources, Apr 2022]
