    Summary
    Enables nuclear import signal receptor activity and nuclear localization sequence binding activity. Involved in nucleocytoplasmic transport; regulation of mitotic nuclear division; and regulation of protein desumoylation. Located in cytoplasm and nucleus. Used to study cancer. Orthologous to human RANBP6 (RAN binding protein 6) and IPO5 (importin 5). [provided by Alliance of Genome Resources, Dec 2024]
