== Function ==
[https://www.uniprot.org/uniprot/VP35_EBOZM VP35_EBOZM] Acsts as a polymerase cofactor in the RNA polymerase transcription and replication complex. Prevents establishment of cellular antiviral state by blocking virus-induced phosphorylation and activation of interferon regulatory factor 3 (IRF3), a transcription factor critical for the induction of interferons alpha and beta. The mechanism by which this blockage occurs remains incompletely defined, a hypothesis suggests that VP35 dsRNA-binding activity prevents activation of IRF3 by sequestering dsRNA. Also inhibits the antiviral effect mediated by the interferon-induced, double-stranded RNA-activated protein kinase EIF2AK2/PKR.<ref>PMID:9971816</ref> <ref>PMID:11027311</ref> <ref>PMID:12829834</ref> <ref>PMID:16495261</ref> <ref>PMID:17065211</ref>
