Asymmetric Unit(hide GO term definitions)
Chain A,B   (VE7_HPV1 | P06465)
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: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:0003700    transcription factor activity, sequence-specific DNA binding    Interacting selectively and non-covalently with a specific DNA sequence in order to modulate transcription. The transcription factor may or may not also interact selectively with a protein or macromolecular complex.
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:0039645    modulation by virus of host G1/S transition checkpoint    Any viral process that modulates the frequency, rate or extent of the host cell G1/S transition checkpoint.
    GO:0060153    modulation by virus of host cell cycle    Any viral process that modulates the rate or extent of progression through the cell cycle.
    GO:0006355    regulation of transcription, DNA-templated    Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.
    GO:0039503    suppression by virus of host innate immune response    Any process in which a virus stops, prevents, or reduces the frequency, rate or extent of the innate immune response of the host organism, the host's first line of defense.
    GO:0039502    suppression by virus of host type I interferon-mediated signaling pathway    Any process in which a virus stops, prevents, or reduces the frequency, rate or extent of type I interferon-mediated signaling in the host organism. Type I interferons include the interferon-alpha, beta, delta, episilon, zeta, kappa, tau, and omega gene families.
    GO:0006351    transcription, DNA-templated    The cellular synthesis of RNA on a template of DNA.
    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:0030430    host cell cytoplasm    The cytoplasm of a host cell.
    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.
