    Summary
    Predicted to enable nuclear import signal receptor activity and nuclear localization sequence binding activity. Involved in NLS-bearing protein import into nucleus and regulation of nucleocytoplasmic transport. Located in P granule and nuclear envelope. Is expressed in several structures, including embryonic/larval central nervous system; germ layer derivative; gonad; and head. Orthologous to human KPNB1 (karyopherin subunit beta 1).
