Asymmetric/Biological Unit(hide GO term definitions)
Chain A   (Q2LG68_9INFA | Q2LG68)
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.
biological process
    GO:0006370    7-methylguanosine mRNA capping    Addition of the 7-methylguanosine cap to the 5' end of a nascent messenger RNA transcript.
    GO:0075526    cap snatching    A transcription initiation process during which a nucleotide sequence between 10 and 20 nucleotides in size is cleaved from the 5' end of host mRNAs by a viral RNA-dependent polymerase. The capped leader sequence obtained is subsequently used to prime transcription on the viral genome, which ultimately leads to the synthesis of capped, translatable viral mRNAs.
    GO:0006397    mRNA processing    Any process involved in the conversion of a primary mRNA transcript into one or more mature mRNA(s) prior to translation into polypeptide.
    GO:0006351    transcription, DNA-templated    The cellular synthesis of RNA on a template of DNA.
cellular component
    GO:0033650    host cell mitochondrion    A semiautonomous, self replicating organelle as found in host cells that occurs in varying numbers, shapes, and sizes in the cell cytoplasm. The host is defined as the larger of the organisms involved in a symbiotic interaction.
    GO:0042025    host cell nucleus    A membrane-bounded organelle as it is found in the host cell in which chromosomes are housed and replicated. The host is defined as the larger of the organisms involved in a symbiotic interaction.
    GO:0019012    virion    The complete fully infectious extracellular virus particle.
