NMR Structure(hide GO term definitions)
Chain A   (GAG_MMTVC | P11284)
molecular function
    GO:0003677    DNA binding    Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0003676    nucleic acid binding    Interacting selectively and non-covalently with any nucleic acid.
    GO:0000166    nucleotide binding    Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose.
    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.
    GO:0008270    zinc ion binding    Interacting selectively and non-covalently with zinc (Zn) ions.
biological process
    GO:0046755    viral budding    A viral process by which enveloped viruses acquire a host-derived membrane enriched in viral proteins to form their external envelope. The process starts when nucleocapsids, assembled or in the process of being built, induce formation of a membrane curvature in the host plasma or organelle membrane and wrap up in the forming bud. The process ends when the bud is eventually pinched off by membrane scission to release the enveloped particle into the lumenal or extracellular space.
    GO:0039702    viral budding via host ESCRT complex    Viral budding which uses a host ESCRT protein complex, or complexes, to mediate the budding process.
    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.
cellular component
    GO:0019028    viral capsid    The protein coat that surrounds the infective nucleic acid in some virus particles. It comprises numerous regularly arranged subunits, or capsomeres.
    GO:0019013    viral nucleocapsid    The complete protein-nucleic acid complex that is the packaged form of the genome in a virus particle.
    GO:0019012    virion    The complete fully infectious extracellular virus particle.
