Names and origin
|Sequence length||109 AA.|
|Protein existence||Inferred from homology|
General annotation (Comments)
Inhibits host transcriptional machinery, by producing modifications to the phosphorylation state of the C-terminal domain (CTD) of RNA polymerase II. Inhibits phosphorylation at serine 2 in the heptapeptide repeat (YSPTSPS) of the CTD of RNA polymerase II, suggesting that the elongation step of transcription and/or 3'-end processing is prevented. Inhibition of host transcription machinery leads to shut off of host cell protein synthesis and inhibition of the host innate immune response. NSs also seems to be involved in the nuclear relocalization of host PABP1 By similarity.
Belongs to the orthobunyavirus NS-S protein family.

|This entry describes 2 isoforms produced by alternative initiation. [Align] [Select]|
|Isoform NSS (identifier: P16992-1) |
This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.
|Note: Produced by alternative initiation in the N gene, but encoded on another frame.|
|Isoform N (identifier: P16993-1) |
The sequence of this isoform can be found in the external entry P16993.
Isoforms of the same protein are often annotated in two different entries if their sequences differ significantly.
