    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: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: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.
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.
