What is the function of this protein?
Replicates the viral (+) and (-) RNA genome, and performs the capping of genomes in the cytoplasm (PubMed:31090058).  Methylates viral RNA cap at guanine N-7 and ribose 2'-O positions.  Once sufficient NS5 is expressed, binds to the cap-proximal structure and inhibits further translation of the viral genome (PubMed:32313955).  Besides its role in RNA genome replication, also prevents the establishment of a cellular antiviral state by blocking the interferon-alpha/beta (IFN-alpha/beta) signaling pathway.  Mechanistically, interferes with host kinases TBK1 and IKKE upstream of interferon regulatory factor 3/IRF3 to inhibit the RIG-I pathway (PubMed:31690057, PubMed:30530224).  Antagonizes also type I interferon signaling by targeting STAT2 for degradation by the proteasome thereby preventing activation of JAK-STAT signaling pathway (PubMed:27212660, PubMed:27797853).  Within the host nucleus, disrupts host SUMO1 and STAT2 co-localization with PML, resulting in PML degradation (By similarity).  May also reduce immune responses by preventing the recruitment of the host PAF1 complex to interferon-responsive genes (By similarity).
What are the official names of this protein?
