Chain A,B,C,D   (C3W5Z1_I09A0 | C3W5Z1)
molecular function
    GO:0003723    RNA binding    Interacting selectively and non-covalently with an RNA molecule or a portion thereof.
    GO:0039660    structural constituent of virion    The action of a molecule that contributes to the structural integrity of a virion.
    GO:0005198    structural molecule activity    The action of a molecule that contributes to the structural integrity of a complex or its assembly within or outside a cell.
biological process
    GO:0039573    suppression by virus of host complement activation    Any process in which a virus stops, prevents, or reduces the frequency, rate or extent of complement activation. The activation of complement involves the sequential proteolysis of proteins to generate enzymes with catalytic activities. The biological functions of the complement include opsonization, inflammation, lysis of immune complexes, or enhancement of the humoral immune response. For example, the virus complement control protein (VCP) of vaccinia virus, and the complement control protein of herpesvirus inhibit C3 convertase.
    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: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:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    GO:0019012    virion    The complete fully infectious extracellular virus particle.
    GO:0055036    virion membrane    The lipid bilayer surrounding a virion.
