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.\nInhibits 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 30KDA 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.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eReference\u003c\/b\u003e: \"The NIAID influenza genome sequencing project.\"\nSpiro D., Ghedin E., Sengamalay N., Halpin R., Boyne A., Zaborsky J., Feldblyum T., Subbu V., Sparenborg J., Shumway M., Sitz J., Katzel D., Koo H., Salzberg S.L., Griesemer S., St George K., Bennett R., Taylor J.
