Enables RNA folding chaperone; molecular adaptor activity; and nucleic acid binding activity. Predicted to be involved in mRNA export from nucleus. 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; future brain; genitourinary system; and sensory organ. Orthologous to human ALYREF (Aly/REF export factor).
