biological process
    GO:0090503    RNA phosphodiester bond hydrolysis, exonucleolytic    The chemical reactions and pathways involving the hydrolysis of terminal 3',5'-phosphodiester bonds in one or two strands of ribonucleotides.
    GO:0030683    evasion or tolerance by virus of host immune response    Any process, either active or passive, by which a virus avoids the effects of the host organism's immune response. The host is defined as the larger of the organisms involved in a symbiotic interaction.
    GO:0039595    induction by virus of catabolism of host mRNA    The process in which a virus increases the frequency, rate or extent of the breakdown of host messenger RNA (mRNA).
    GO:0039520    induction by virus of host autophagy    Any process in which a virus activates or increases the frequency, rate or extent of autophagy in the host.
    GO:0032259    methylation    The process in which a methyl group is covalently attached to a molecule.
    GO:0039648    modulation by virus of host protein ubiquitination    Any process in which a virus modulates the frequency, rate or extent of protein ubiquitination in the host organism. Ubiquitination is the process in which one or more ubiquitin groups are added to a protein.
    GO:0090305    nucleic acid phosphodiester bond hydrolysis    The nucleic acid metabolic process in which the phosphodiester bonds between nucleotides are cleaved by hydrolysis.
    GO:0006508    proteolysis    The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds.
    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.
    GO:0039503    suppression by virus of host innate immune response    Any process in which a virus stops, prevents, or reduces the frequency, rate or extent of the innate immune response of the host organism, the host's first line of defense.

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.

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.
