Asymmetric/Biological Unit(hide GO term definitions)
Chain A,B,C   (ENV_HV1LW | Q70626)
molecular function
    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:0075512    clathrin-dependent endocytosis of virus by host cell    Any clathrin-mediated endocytosis that is involved in the uptake of a virus into a host cell. Begins by invagination of a specific region of the host cell plasma membrane around the bound virus to form a clathrin-coated pit, which then pinches off to form a clathrin-coated endocytic vesicle containing the virus.
    GO:0075509    endocytosis involved in viral entry into host cell    Any endocytosis that is involved in the uptake of a virus into a host cell.
    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:0039654    fusion of virus membrane with host endosome membrane    Fusion of a virus membrane with a host endosome membrane. Occurs after internalization of the virus through the endosomal pathway, and results in release of the virus contents into the cell.
    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:0039663    membrane fusion involved in viral entry into host cell    Merging of the virion membrane and a host membrane (host plasma membrane or host organelle membrane) that is involved in the uptake of a virus into a host cell.
    GO:0002223    stimulatory C-type lectin receptor signaling pathway    Any series of molecular signals generated as a consequence of binding to a C-type lectin receptor capable of cellular activation.
    GO:0046718    viral entry into host cell    The process that occurs after viral attachment by which a virus, or viral nucleic acid, breaches the plasma membrane or cell envelope and enters the host cell. The process ends when the viral nucleic acid is released into the host cell cytoplasm.
    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:0019082    viral protein processing    Any protein maturation process achieved by the cleavage of a peptide bond or bonds within a viral protein.
    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:0044174    host cell endosome    A membrane-bounded organelle that carries materials newly ingested by endocytosis. It passes many of the materials to host cell lysosomes for degradation.
    GO:0044175    host cell endosome membrane    The lipid bilayer surrounding a host cell endosome.
    GO:0033644    host cell membrane    Double layer of lipid molecules as it encloses host cells, and, in eukaryotes, many organelles; may be a single or double lipid bilayer; also includes associated proteins. The host is defined as the larger of the organisms involved in a symbiotic interaction.
    GO:0020002    host cell plasma membrane    The plasma membrane surrounding a host cell.
    GO:0016021    integral component of membrane    The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    GO:0019031    viral envelope    The lipid bilayer of a virion that surrounds the protein capsid. May also contain glycoproteins.
    GO:0019012    virion    The complete fully infectious extracellular virus particle.
    GO:0055036    virion membrane    The lipid bilayer surrounding a virion.
