	GO:0006508	proteolysis	The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds.
	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.
	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:0006351	transcription, DNA-templated	The cellular synthesis of RNA on a template of DNA.
	GO:0001172	transcription, RNA-templated	The cellular synthesis of RNA on a template of RNA.
	GO:0039694	viral RNA genome replication	The replication of a viral RNA genome.
	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.
	GO:0019083	viral transcription	The process by which a viral genome, or part of a viral genome, is transcribed within the host cell.
cellular component
	GO:0030430	host cell cytoplasm	The cytoplasm of a host cell.
	GO:0044172	host cell endoplasmic reticulum-Golgi intermediate compartment	A complex system of membrane-bounded compartments located between host cell endoplasmic reticulum (ER) and the host Golgi complex, with a distinctive membrane protein composition; involved in ER-to-Golgi transport.
	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.
