Asymmetric/Biological Unit(hide GO term definitions)
Chain A   (NCAP_LASSJ | P13699)
molecular function
    GO:0008408    3'-5' exonuclease activity    Catalysis of the hydrolysis of ester linkages within nucleic acids by removing nucleotide residues from the 3' end.
    GO:0003723    RNA binding    Interacting selectively and non-covalently with an RNA molecule or a portion thereof.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
biological process
    GO:0039696    RNA-templated viral transcription    A transcription process that uses viral RNA as a template.
    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:0039689    negative stranded viral RNA replication    A viral genome replication process where the template genome is negative stranded, single stranded RNA ((-)ssRNA).
    GO:0090305    nucleic acid phosphodiester bond hydrolysis    The nucleic acid metabolic process in which the phosphodiester bonds between nucleotides are cleaved by hydrolysis.
    GO:0039724    suppression by virus of host IKBKE activity    Any process in which a virus stops, prevents, or reduces the activity of the host I-kappa-B kinase epsilon (IKBKE/IKK-epsilon/IKK-E).
    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: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.
cellular component
    GO:0019029    helical viral capsid    The protein coat that surrounds the infective nucleic acid in some virus particles; the subunits are arranged to form a protein helix with the genetic material contained within. Tobacco mosaic virus has such a capsid structure.
    GO:0030430    host cell cytoplasm    The cytoplasm of a host cell.
    GO:0019028    viral capsid    The protein coat that surrounds the infective nucleic acid in some virus particles. It comprises numerous regularly arranged subunits, or capsomeres.
    GO:0019013    viral nucleocapsid    The complete protein-nucleic acid complex that is the packaged form of the genome in a virus particle.
    GO:0019012    virion    The complete fully infectious extracellular virus particle.
