CC   -!- FUNCTION: Export receptor for importin alpha. Mediates importin-alpha
CC       re-export from the nucleus to the cytoplasm after import substrates
CC       have been released into the nucleoplasm (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Binds with high affinity to importin-alpha only in the
CC       presence of RanGTP. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Nucleus envelope
CC       {ECO:0000269|PubMed:10759889, ECO:0000269|PubMed:16823372}.
CC   -!- SIMILARITY: Belongs to the XPO2/CSE1 family. {ECO:0000305}.
