molecular function |

| GO:0008026 | | ATP-dependent helicase activity | | Catalysis of the reaction: ATP + H2O = ADP + phosphate, to drive the unwinding of a DNA or RNA helix. |
| GO:0003723 | | RNA binding | | Interacting selectively and non-covalently with an RNA molecule or a portion thereof. |
| GO:0003724 | | RNA helicase activity | | Catalysis of the reaction: NTP + H2O = NDP + phosphate, to drive the unwinding of a RNA helix. |
| GO:0003725 | | double-stranded RNA binding | | Interacting selectively and non-covalently with double-stranded RNA. |
| GO:0016787 | | hydrolase activity | | Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3. |
| GO:0017111 | | nucleoside-triphosphatase activity | | Catalysis of the reaction: a nucleoside triphosphate + H2O = nucleoside diphosphate + phosphate. |
| 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:0008233 | | peptidase activity | | Catalysis of the hydrolysis of a peptide bond. A peptide bond is a covalent bond formed when the carbon atom from the carboxyl group of one amino acid shares electrons with the nitrogen atom from the amino group of a second amino acid. |
| GO:0046983 | | protein dimerization activity | | The formation of a protein dimer, a macromolecular structure consists of two noncovalently associated identical or nonidentical subunits. |
| GO:0008236 | | serine-type peptidase activity | | Catalysis of the hydrolysis of peptide bonds in a polypeptide chain by a catalytic mechanism that involves a catalytic triad consisting of a serine nucleophile that is activated by a proton relay involving an acidic residue (e.g. aspartate or glutamate) and a basic residue (usually histidine). |
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: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: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:0006508 | | proteolysis | | The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds. |
| 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:0019079 | | viral genome replication | | Any process involved directly in viral genome replication, including viral nucleotide metabolism. |
| 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: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: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:0044165 | | host cell endoplasmic reticulum | | The irregular network of unit membranes, visible only by electron microscopy, that occurs in the host cell cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The host ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached). |
| GO:0044167 | | host cell endoplasmic reticulum membrane | | The lipid bilayer surrounding the host cell endoplasmic reticulum. |
| 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: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: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:0019031 | | viral envelope | | The lipid bilayer of a virion that surrounds the protein capsid. May also contain glycoproteins. |
| 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. |
| GO:0055036 | | virion membrane | | The lipid bilayer surrounding a virion. |
