SARS-Co V protein 6(P6) is one of the previously studied accessory proteins that have been documented to enhance viral replication and suppress host interferon(IFN) signaling pathways. Through yeast two-hybrid screening, we identified eight potential cellular P6-interacting proteins from a human spleen c DNA library. For further investigation, we targeted the IFN signaling pathway-mediating protein, N-Myc(and STAT) interactor(Nmi). Its interaction with P6 was confirmed within cells. The results showed that P6 can promote the ubiquitin-dependent proteosomal degradation of Nmi. This study revealed a new mechanism of SARS-Co V P6 in limiting the IFN signaling to promote SARS-Co V survival in host cells.展开更多
