Jr., Holloway B.P., Obijeski J.F.; RT "Molecular cloning and sequencing of the La Crosse virus S RNA."; RL Virology 128:463-468(1983). CC -!- FUNCTION: Inhibits host transcriptional machinery, by producing CC modifications to the phosphorylation state of the C-terminal domain CC (CTD) of RNA polymerase II. Inhibits phosphorylation at serine 2 in the CC heptapeptide repeat (YSPTSPS) of the CTD of RNA polymerase II, CC suggesting that the elongation step of transcription and/or 3'-end CC processing is prevented. Inhibition of host transcription machinery CC leads to shut off of host cell protein synthesis and inhibition of the CC host innate immune response. NSs also seems to be involved in the CC nuclear relocalization of host PABP1 (By similarity). {ECO:0000250}. CC -!- ALTERNATIVE PRODUCTS: CC Event=Alternative initiation; Named isoforms=2; CC Name=NSS; CC IsoId=P04874-1; Sequence=Displayed; CC Name=N; CC IsoId=P04873-1; Sequence=External; CC -!- MISCELLANEOUS: [Isoform NSS]: Produced by alternative initiation in the CC N gene, but encoded on another frame. CC -!- SIMILARITY: Belongs to the orthobunyavirus NS-S protein family. CC {ECO:0000305}.
