NSs forms large aggregates in the nucleus and impairs induction of the antiviral type I IFN system by several mechanisms, including degradation of subunit p62 of the general RNA polymerase II transcription factor TFIIH. Here, we show that depletion of the nuclear pore protein Nup98 affects the nuclear import of NSs. Nonetheless, NSs was still able to degrade TFIIH-p62 under these conditions. Depletion of Nup98, however, had a negative effect on Rift Valley fever virus multiplication. Our data thus indicate that NSs utilizes Nup98 for import into the nucleus, but also plays a general role in the viral replication cycle.", }
