CC -!- FUNCTION: Binds to conventional NLS motifs and mediates nuclear protein
CC import across the nuclear envelope (By similarity). Acts as cellular
CC receptor for the nuclear import of the virD2 protein of Agrobacterium,
CC but is not essential for Agrobacterium-mediated root transformation
CC (PubMed:18836040). {ECO:0000250|UniProtKB:Q96321,
CC ECO:0000269|PubMed:18836040}.
CC -!- SUBUNIT: Forms a complex with importin subunit beta-1.
CC {ECO:0000250|UniProtKB:Q96321}.

CC -!- SUBCELLULAR LOCATION: Nucleus envelope {ECO:0000250|UniProtKB:Q96321}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=1;
CC Comment=A number of isoforms are produced. According to EST
CC sequences. {ECO:0000305};
CC Name=1;
CC IsoId=Q9FWY7-1; Sequence=Displayed;
CC -!- SIMILARITY: Belongs to the importin alpha family. {ECO:0000305}.
