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.

	GO:0039502	suppression by virus of host type I interferon-mediated signaling pathway	Any process in which a virus stops, prevents, or reduces the frequency, rate or extent of type I interferon-mediated signaling in the host organism.

	GO:0016032	viral process	A multi-organism process in which a virus is a participant. The other participant is the host. Includes infection of a host cell, replication of the viral genome, and assembly of progeny virus particles. In some cases the viral genetic material may integrate into the host genome and only subsequently, under particular circumstances, 'complete' its life cycle.

	GO:0008242	omega peptidase activity	Catalysis of the removal of terminal peptide residues that are substituted, cyclized or linked by isopeptide bonds (peptide linkages other than those of alpha-carboxyl to alpha-amino groups).
	GO:0008233	peptidase activity	Catalysis of the hydrolysis of a peptide bond. A peptide bond is a covalent bond formed when the carbon atom from the carboxyl group of one amino acid shares electrons with the nitrogen atom from the amino group of a second amino acid.
	GO:0036459	thiol-dependent ubiquitinyl hydrolase activity	Catalysis of the thiol-dependent hydrolysis of an ester, thioester, amide, peptide or isopeptide bond formed by the C-terminal glycine of ubiquitin.
	GO:0016740	transferase activity	Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
	GO:0008270	zinc ion binding	Interacting selectively and non-covalently with zinc (Zn) ions.
biological process
	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: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:0039548	suppression by virus of host IRF3 activity	Any process in which a virus stops, prevents, or reduces the activity of host IRF3 (interferon regulatory factor-3), a transcription factor in the RIG-I/MDA-5 signaling pathway. Viral infection triggers phosphorylation of cytoplasmic IRF3, which allows IRF3 to form a homodimer, migrate to the nucleus, and activate transcription of IFN-alpha and IFN-beta 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: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.
	GO:0039502	suppression by virus of host type I interferon-mediated signaling pathway	Any process in which a virus stops, prevents, or reduces the frequency, rate or extent of type I interferon-mediated signaling in the host organism. Type I interferons include the interferon-alpha, beta, delta, episilon, zeta, kappa, tau, and omega gene families.
	GO:0001172	transcription, RNA-templated	The cellular synthesis of RNA on a template of RNA.
	GO:0019079	viral genome replication	Any process involved directly in viral genome replication, including viral nucleotide metabolism.
	GO:0016032	viral process	A multi-organism process in which a virus is a participant. The other participant is the host. Includes infection of a host cell, replication of the viral genome, and assembly of progeny virus particles. In some cases the viral genetic material may integrate into the host genome and only subsequently, under particular circumstances, 'complete' its life cycle.
	GO:0019082	viral protein processing	Any protein maturation process achieved by the cleavage of a peptide bond or bonds within a viral protein.
cellular component
	GO:0030430	host cell cytoplasm	The cytoplasm of a host cell.
	GO:0033644	host cell membrane	Double layer of lipid molecules as it encloses host cells, and, in eukaryotes, many organelles; may be a single or double lipid bilayer; also includes associated proteins. The host is defined as the larger of the organisms involved in a symbiotic interaction.
	GO:0044220	host cell perinuclear region of cytoplasm	The host cell cytoplasm situated near, or occurring around, the host nucleus.
	GO:0016021	integral component of membrane	The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
	GO:0016020	membrane	A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
