Protein
Non-structural protein 1
Gene
N/A
Organism
Rotavirus A (isolate Equine/United Kingdom/L338/1988 G13-P12[18]-I6-Rx-Cx-M6-A6-Nx-Tx-Ex-Hx) (RV-A)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

Seems to induce the proteasome-dependent degradation of IRF3, IRF5 and IRF7, thereby antagonizing the cellular interferon response and establishment of the antiviral state. Binds and targets IRF3 early post-infection and suppresses IRF3 nuclear translocation By similarity.

Domaini

The zinc-finger domain is important, but not sufficient for binding and degrading IRF3. It is sometimes described as a RING zinc-finger, but it is atypical and it is unclear whether it is related with ubiquitin ligase activity By similarity.

Sequence similaritiesi

Belongs to the rotavirus A NSP1 family.
