molecular function |
| 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:0039657 | | suppression by virus of host gene expression | | Any process in which a virus stops, prevents, or reduces the frequency, rate or extent of gene expression in the host organism. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA (for protein-coding genes) and the translation of that mRNA into protein. Some protein processing events may be included when they are required to form an active form of a product from an inactive precursor form. |
| GO:0039522 | | suppression by virus of host mRNA export from nucleus | | Any process in which a virus stops, prevents, or reduces the frequency, rate or extent of movement of mRNA from the nucleus to the cytoplasm in the host organism. |
| 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:0033645 | | host cell endomembrane system | | A collection of membranous structures involved in transport within the host cell. The main components of the endomembrane system are endoplasmic reticulum, Golgi bodies, vesicles, cell membrane and nuclear envelope. Members of the endomembrane system pass materials through each other or though the use of vesicles. The host is defined as the larger of the organisms involved in a symbiotic interaction. |
| 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:0044200 | | host cell nuclear membrane | | Either of the lipid bilayers that surround the host nucleus and form the nuclear envelope; excludes the intermembrane space. |
| 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: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. |
