Chain A,B   (R1A_BCHK4 | P0C6T4)
molecular function
    GO:0003723    RNA binding    Interacting selectively and non-covalently with an RNA molecule or a portion thereof.
    GO:0003968    RNA-directed 5'-3' RNA polymerase activity    Catalysis of the reaction: nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1); uses an RNA template, i.e. the catalysis of RNA-template-directed extension of the 3'-end of an RNA strand by one nucleotide at a time.
    GO:0004197    cysteine-type endopeptidase activity    Catalysis of the hydrolysis of internal, alpha-peptide bonds in a polypeptide chain by a mechanism in which the sulfhydryl group of a cysteine residue at the active center acts as a nucleophile.
    GO:0008234    cysteine-type peptidase activity    Catalysis of the hydrolysis of peptide bonds in a polypeptide chain by a mechanism in which the sulfhydryl group of a cysteine residue at the active center acts as a nucleophile.
    GO:0016787    hydrolase activity    Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0003676    nucleic acid binding    Interacting selectively and non-covalently with any nucleic acid.
    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: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.
