| molecular function |
|---|
| | GO:0030369 | | ICAM-3 receptor activity | | Combining with ICAM-3, intercellular adhesion molecule 3, and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity. ICAM-3, or CD50, are constitutively expressed on monocytes, granulocytes and lymphocytes; on physiological stimulation, they become transiently phosphorylated on serine residues. |
| | GO:0048306 | | calcium-dependent 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), in the presence of calcium. |
| | GO:0030246 | | carbohydrate binding | | Interacting selectively and non-covalently with any carbohydrate, which includes monosaccharides, oligosaccharides and polysaccharides as well as substances derived from monosaccharides by reduction of the carbonyl group (alditols), by oxidation of one or more hydroxy groups to afford the corresponding aldehydes, ketones, or carboxylic acids, or by replacement of one or more hydroxy group(s) by a hydrogen atom. Cyclitols are generally not regarded as carbohydrates. |
| | GO:0005537 | | mannose binding | | Interacting selectively and non-covalently with mannose, a monosaccharide hexose, stereoisomeric with glucose, that occurs naturally only in polymerized forms called mannans. |
| | GO:0046872 | | metal ion binding | | Interacting selectively and non-covalently with any metal ion. |
| | GO:0042605 | | peptide antigen binding | | Interacting selectively and non-covalently with an antigen peptide. |
| | GO:0004872 | | receptor activity | | Combining with an extracellular or intracellular messenger to initiate a change in cell activity. |
| | GO:0046790 | | virion binding | | Interacting selectively and non-covalently with a virion, either by binding to components of the capsid or the viral envelope. |
| | GO:0001618 | | virus receptor activity | | Combining with a virus component and mediating entry of the virus into the cell. |
| biological process |
|---|
| | GO:0002250 | | adaptive immune response | | An immune response mediated by cells expressing specific receptors for antigen produced through a somatic diversification process, and allowing for an enhanced secondary response to subsequent exposures to the same antigen (immunological memory). |
| | GO:0019882 | | antigen processing and presentation | | The process in which an antigen-presenting cell expresses antigen (peptide or lipid) on its cell surface in association with an MHC protein complex. |
| | GO:0009988 | | cell-cell recognition | | Cell recognition between cells. May involve the formation of specialized cell junctions. |
| | GO:0006897 | | endocytosis | | A vesicle-mediated transport process in which cells take up external materials or membrane constituents by the invagination of a small region of the plasma membrane to form a new membrane-bounded vesicle. |
| | GO:0002376 | | immune system process | | Any process involved in the development or functioning of the immune system, an organismal system for calibrated responses to potential internal or invasive threats. |
| | GO:0045087 | | innate immune response | | Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens. |
| | GO:0035556 | | intracellular signal transduction | | The process in which a signal is passed on to downstream components within the cell, which become activated themselves to further propagate the signal and finally trigger a change in the function or state of the cell. |
| | GO:0075733 | | intracellular transport of virus | | The directed movement of a virus, or part of a virus, within the host cell. |
| | GO:0007159 | | leukocyte cell-cell adhesion | | The attachment of a leukocyte to another cell via adhesion molecules. |
| | GO:0019048 | | modulation by virus of host morphology or physiology | | The process in which a virus effects a change in the structure or processes of its host organism. |
| | GO:0046968 | | peptide antigen transport | | The directed movement of a peptide antigen into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. The peptide antigen is typically, but not always, processed from an endogenous or exogenous protein. |
| | GO:0030193 | | regulation of blood coagulation | | Any process that modulates the frequency, rate or extent of blood coagulation. |
| | GO:0010468 | | regulation of gene expression | | Any process that modulates the frequency, rate or extent of gene expression. 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 or circRNA (for protein-coding genes) and the translation of that mRNA or circRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form. |
| | 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:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| | 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: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:0005887 | | integral component of plasma membrane | | The component of the plasma 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:0005886 | | plasma membrane | | The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. |
