Predicted to enable nuclear import signal receptor activity and nuclear localization sequence binding activity. Predicted to be involved in NLS-bearing protein import into nucleus. Predicted to act upstream of or within several processes, including entry of viral genome into host nucleus through nuclear pore complex via importin; positive regulation of macromolecule metabolic process; and protein import into nucleus. Predicted to be located in cytoplasm and host cell. Predicted to be active in nucleoplasm. Orthologous to human KPNA6 (karyopherin subunit alpha 6).
