Gene
N/A
Organism
Rotavirus A (isolate Human/United States/WI61/1983 G9-P1A[8]-I1-R1-C1-M1-A1-N1-T1-E1-H1) (RV-A)
Status
Reviewed-Annotation score: 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).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).By similarity

Sequence similaritiesi

Belongs to the rotavirus A NSP1 family.Curated

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into Uniref entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
