S. pombe Rae1 is required for nuclear export of poly(A)+ RNA; rae1-1 temperature-sensitive mutant accumulates poly(A)+ RNA in the nucleus, and loss of rae1 also causes actin/tubulin disorganization and irreversible G2/M cell cycle arrest. Rae1 encodes a WD40-repeat protein. |

Mammalian RAE1 binds directly to a GLEBS-like motif in NUP98 at the nuclear pore complex through multiple domains including WD-repeats and C-terminal extension; RAE1 shuttles between nucleus and cytoplasm in a temperature-dependent, RanGTP-independent manner; overexpression of the GLEBS-like motif inhibits NUP98 binding of RAE1 and causes nuclear accumulation of poly(A)+ RNA, establishing direct RAE1-NUP98 interaction as required for mRNA export. |

RAE1 and H60 compete directly for NKG2D occupancy, with H60 binding ~25-fold more tightly; the two interactions have distinct thermodynamic profiles (RAE1 interaction less temperature-dependent and makes less use of electrostatics). |

Rae1 overexpression corrects both Rae1 and Bub3 haploinsufficiency. Combined Rae1/Bub3 haploinsufficiency greatly increases premature sister chromatid separation and tumorigenesis susceptibility. |

Rae1 and Nup98 form a complex with Cdh1-activated APC (APC-Cdh1) in early mitosis and specifically inhibit APC-Cdh1-mediated ubiquitination of securin (but not cyclin B); combined Rae1/Nup98 haploinsufficiency causes premature securin destruction, premature sister chromatid separation, and severe aneuploidy. Dissociation of Rae1-Nup98 from APC-Cdh1 coincides with BubR1 release from APC-Cdc20 at the metaphase-to-anaphase transition. |
