Asymmetric/Biological Unit(hide GO term definitions)
Chain A,B   (M1_I34A1 | P03485)
molecular function
    GO:0003723    RNA binding    Interacting selectively and non-covalently with an RNA molecule or a portion thereof.
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
    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: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:0019064    fusion of virus membrane with host plasma membrane    Fusion of a viral membrane with the host cell membrane during viral entry. Results in release of the virion contents into the cytoplasm.
    GO:0075733    intracellular transport of virus    The directed movement of a virus, or part of a virus, within the host cell.
    GO:0019065    receptor-mediated endocytosis of virus by host cell    Any receptor-mediated endocytosis that is involved in the uptake of a virus into a host cell; successive instances of virus endocytosis result in the accumulation of virus particles within the cell.
    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:0019061    uncoating of virus    The process by which an incoming virus is disassembled in the host cell to release a replication-competent viral genome.
    GO:0046761    viral budding from plasma membrane    A viral budding that starts with formation of a membrane curvature in the host plasma membrane.
    GO:0019070    viral genome maturation    The processes involved in creating a mature, stable viral genome. Begins after genome replication with a newly synthesized nucleic acid and ends when the genome is ready to be packaged. Includes the addition of proteins to the newly synthesized genome, and DNA repair processes.
    GO:0019072    viral genome packaging    The encapsulation of the viral genome within the capsid.
    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:0019076    viral release from host cell    The dissemination of mature viral particles from the host cell, e.g. by cell lysis or the budding of virus particles from the cell membrane.
    GO:0019083    viral transcription    The process by which a viral genome, or part of a viral genome, is transcribed within the host cell.
    GO:0019068    virion assembly    A late phase of the viral life cycle during which all the components necessary for the formation of a mature virion collect at a particular site in the cell and the basic structure of the virus particle is formed.
    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:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
    GO:0030666    endocytic vesicle membrane    The lipid bilayer surrounding an endocytic vesicle.
    GO:0031904    endosome lumen    The volume enclosed by the membrane of an endosome.
    GO:0005576    extracellular region    The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
    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:0005654    nucleoplasm    That part of the nuclear content other than the chromosomes or the nucleolus.
    GO:0005886    plasma membrane    The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
    GO:0019012    virion    The complete fully infectious extracellular virus particle.
    GO:0055036    virion membrane    The lipid bilayer surrounding a virion.
