靶點(diǎn)詳情

  • 功能：
    Prevents the establishment of the cellular antiviral state by inhibiting TRIM25-mediated DDX58 ubiquitination, which normally triggers the antiviral transduction signal that leads to the activation of type I IFN genes by transcription factors IRF3 and IRF7. Prevents human EIF2AK2/PKR activation, either by binding double-strand RNA, or by interacting directly with EIF2AK2/PKR. This function may be important at the very beginning of the infection, when NS1 is mainly present in the cytoplasm. Also binds poly(A) and U6 snRNA.; Inhibits post-transcriptional processing of cellular pre-mRNA, by binding and inhibiting two cellular proteins that are required for the 3'-end processing of cellular pre-mRNAs: the 30 kDa cleavage and polyadenylation specificity factor/CPSF4 and the poly(A)-binding protein 2/PABPN1. In turn, unprocessed 3' end pre-mRNAs accumulate in the host nucleus and are no longer exported to the cytoplasm. Cellular protein synthesis is thereby shut off very early after virus infection. Viral protein synthesis is not affected by the inhibition of the cellular 3' end processing machinery because the poly(A) tails of viral mRNAs are produced by the viral polymerase through a stuttering mechanism.
  • 基因功能參考文獻(xiàn)：
    1. A recombinant pandemic H1N1 virus containing PA, PA-X, and NS1 genes from currently circulating viruses is fitter in replication in cultured cells and in mice and is slightly more pathogenic than the original ancestor pandemic H1N1 virus. PMID: 30021892
    2. Results confirm that Influenza A virus (IAV) mutant lacking NS1 differs from wild-type in that it induces the production of readily detectable levels of Dicer-dependent viral siRNAs in infected human cells. However, data also demonstrate that these siRNAs have little if any inhibitory effect on IAV gene expression. This is likely due, at least in part, to their inefficient loading into RNA-induced silencing complexes. PMID: 29903832

    21. hnRNP A2/B1 plays an inhibitory role in the replication of influenza A virus through suppressing NS1 RNA/protein levels and NS1 mRNA nucleocytoplasmic translocation. PMID: 24418537
