== Function ==
[[http://www.uniprot.org/uniprot/NCAP_EBOZM NCAP_EBOZM]] Encapsidates the genome, protecting it from nucleases. The encapsidated genomic RNA is termed the nucleocapsid and serves as template for transcription and replication. During replication, encapsidation by NP is coupled to RNA synthesis and all replicative products are resistant to nucleases. [[http://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>
