Protein
Non-structural protein 1
Gene
N/A
Organism
Rotavirus A (strain Human/United Kingdom/ST3/1975 G4-P2A[6]-I1-R1-C1-M1-A1-N1-T1-E1-H1) (RV-A) (Rotavirus A (strain St. Thomas 3))
Status
Reviewed - Annotation score: 3 out of 5 - Experimental evidence at transcript leveli

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.
