CC -!- FUNCTION: Mediates the nuclear export of encapsidated genomic RNAs CC (ribonucleoproteins, RNPs). Acts as an adapter between viral RNPs CC complexes and the nuclear export machinery of the cell. Possesses CC no intrinsic RNA-binding activity, but includes a C-terminal M1- CC binding domain. This domain is believed to allow recognition of CC RNPs bound to the protein M1. Since protein M1 is not available in CC large quantities before late stages of infection, such an indirect CC recognition mechanism probably ensures that genomic RNPs are not CC exported from the host nucleus until sufficient quantities of CC viral mRNA and progeny genomic RNA have been synthesized. CC Furthermore, the RNPs enter the host cytoplasm only when CC associated with the M1 protein that is necessary to guide them to CC the plasma membrane. May down-regulate viral RNA synthesis when CC overproduced. {ECO:0000256|HAMAP-Rule:MF_04067, CC ECO:0000256|RuleBase:RU362104, ECO:0000256|SAAS:SAAS00967765}. CC -!- SUBUNIT: Binds M1 protein.
