    GO:0000166    nucleotide binding    Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose.

Transferase is the systematic name for any enzyme of EC class 2.
biological process
    GO:0006260    DNA replication    The cellular metabolic process in which a cell duplicates one or more molecules of DNA. DNA replication begins when specific sequences, known as origins of replication, are recognized and bound by initiation proteins, and ends when the original DNA molecule has been completely duplicated and the copies topologically separated. The unit of replication usually corresponds to the genome of the cell, an organelle, or a virus. The template for replication can either be an existing DNA molecule or RNA.
    GO:0018144    RNA-protein covalent cross-linking    The formation of a covalent cross-link between RNA and a protein.
    GO:0075509    endocytosis involved in viral entry into host cell    Any endocytosis that is involved in the uptake of a virus into a host cell.
    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: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:0034220    ion transmembrane transport    A process in which an ion is transported from one side of a membrane to the other by means of some agent such as a transporter or pore.
    GO:0006811    ion transport    The directed movement of charged atoms or small charged molecules into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
    GO:0039707    pore formation by virus in membrane of host cell    The aggregation, arrangement and bonding together of a set of components by a virus to form a pore complex in a membrane of a host organism.
    GO:0044694    pore-mediated entry of viral genome into host cell    Injection by a non-enveloped virus of the viral genome into the host cytoplasm through creation of a pore or channel in the host cell membrane(s). Usually mediated by a viral pore-forming peptide associated with the viral capsid or bacteriophage tail.
    GO:0039690    positive stranded viral RNA replication    A viral genome replication process where the template genome is positive stranded, single stranded RNA ((+)ssRNA). Replication of the positive strand leads to dsRNA formation, which in turn is transcribed into positive single stranded RNA.
    GO:0051259    protein oligomerization    The process of creating protein oligomers, compounds composed of a small number, usually between three and ten, of component monomers; protein oligomers may be composed of different or identical monomers. Oligomers may be formed by the polymerization of a number of monomers or the depolymerization of a large protein polymer.
    GO:0006508    proteolysis    The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds.
    GO:0039540    suppression by virus of host RIG-I activity    Any process in which a virus stops, prevents, or reduces the activity of RIG-1 (also known as DDX58). The cytoplasmic pattern recognition RIG-I recognizes viral RNA synthesized during active viral replication and signals to protect the host against viral infection, for example by inducing the expression of antiviral cytokines.
    GO:0039544    suppression by virus of host RIG-I activity by RIG-I proteolysis    The chemical reactions and pathways performed by a virus resulting in the hydrolysis of the host RIG-I protein (also known as DDX58) by cleavage of peptide bonds, thereby inhibiting RIG-I signal transduction.
    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:0039522    suppression by virus of host mRNA export from nucleus    Any process in which a virus stops, prevents, or reduces the frequency, rate or extent of movement of mRNA from the nucleus to the cytoplasm in the host organism.
    GO:0039611    suppression by virus of host translation initiation factor activity    Any process in which a virus prevents or reduces the frequency, rate or extent of activity of a host translation initiation factor.
    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:0006810    transport    The directed movement of substances (such as macromolecules, small molecules, ions) or cellular components (such as complexes and organelles) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter, pore or motor protein.
    GO:0039694    viral RNA genome replication    The replication of a viral RNA genome.
    GO:0046718    viral entry into host cell    The process that occurs after viral attachment by which a virus, or viral nucleic acid, breaches the plasma membrane or cell envelope and enters the host cell. The process ends when the viral nucleic acid is released into the host cell cytoplasm.
    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:0019062    virion attachment to host cell    The process by which a virion protein binds to molecules on the host cellular surface or host cell surface projection.
cellular component
    GO:0039618    T=pseudo3 icosahedral viral capsid    The protein coat that surrounds the infective nucleic acid in some virus particles where the subunits (capsomeres) are arranged to form an icosahedron with pseudo T=3 symmetry.
