    GO:0039549    suppression by virus of host IRF3 activity by inhibition of IRF3 phosphorylation    Any process in which a virus stops, prevents, or reduces the rate or extent of the phosphorylation of IRF3 (interferon regulatory factor-3), thereby inhibiting IRF3 activation. In response to signaling from RIG-1/MDA-5 receptors, IRF3 is phosphorylated on multiple serine and threonine residues; phosphorylation results in the cytoplasm-to-nucleus translocation of IRF3, DNA binding, and increased transcriptional activation of interferon-encoding genes.
    GO:0039579    suppression by virus of host ISG15 activity    Any process in which a virus stops, prevents, or reduces the frequency, rate or extent of host ubiquitin-like protein ISG15 activity. ISG15 is a ubiquitin-like protein that is conjugated to lysine residues on various target proteins. Viruses escape from the antiviral activity of ISG15 by using different mechanisms; the influenza B virus NS1 protein for instance blocks the covalent linkage of ISG15 to its target proteins by directly interacting with ISG15. The papain-like protease from the coronavirus cleaves ISG15 derivatives.
    GO:0039644    suppression by virus of host NF-kappaB transcription factor activity    Any process in which a virus stops, prevents, or reduces the activity of host NF-kappaB activity.
    GO:0039657    suppression by virus of host gene expression    Any process in which a virus stops, prevents, or reduces the frequency, rate or extent of gene expression in the host organism. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA (for protein-coding genes) and the translation of that mRNA into protein. Some protein processing events may be included when they are required to form an active form of a product from an inactive precursor form.
