Predicted to enable RNA binding activity. Predicted to be involved in mRNA export from nucleus and viral mRNA export from host cell nucleus. Predicted to act upstream of or within RNA splicing and mRNA transport. Predicted to be located in cytosol and nuclear speck. Predicted to be part of THO complex part of transcription export complex. Predicted to colocalize with chromosome, telomeric region. Is expressed in inferior colliculus; midbrain ventricular layer; submandibular gland primordium; telencephalon ventricular layer; and vibrissa. Orthologous to human THOC7 (THO complex 7).
