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 {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the XPO2/CSE1 family. {ECO:0000305}.
