Sequence statusComplete.
Protein existenceInferred from homology

General annotation (Comments)

Function

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.

Subunit structure

Interacts (via C-terminus) with host IRF3; this interaction leads to IRF3 degradation. Interacts with host IRF7; this interaction leads to IRF7 degradation By similarity.

Subcellular location

Host cytoplasmhost cytoskeleton By similarity.

Domain

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 similarities

Belongs to the rotavirus A NSP1 family.
