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=N;
CC         IsoId=P03513-1; 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}.
