UniProtKB - P21605 (E3_VACCW)
Protein
Protein E3
Gene
VACWR059
Organism
Vaccinia virus (strain Western Reserve) (VACV) (Vaccinia virus (strain WR))
Status
Functioni
Plays a role in the inhibition of multiple cellular antiviral responses activated by dsRNA, such as inhibition of PKR activation, apoptosis, and IFN-mediated antiviral activities (PubMed:1681618, PubMed:18604270, PubMed:24257616, PubMed:25740987). Blocks also the phosphorylation and subsequent activation of IRF3 and IRF7 kinases that are required for interferon-alpha gene expression (By similarity). Inhibits NF-kappa-B activation and the ubiquitin-like protein ISG15, which is an early antiviral protein (PubMed:18604270, PubMed:24257616). The binding with host ISG15 subsequently blocks host ISGylation (PubMed:18604270, PubMed:24257616). Inhibits ZBP1-dependent necroptosis via interaction with host ZBP1 (PubMed:29073079).By similarity5 Publications
