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.
