molecular function |
| GO:0003823 | | antigen binding | | Interacting selectively and non-covalently with an antigen, any substance which is capable of inducing a specific immune response and of reacting with the products of that response, the specific antibody or specifically sensitized T-lymphocytes, or both. Binding may counteract the biological activity of the antigen. |
| GO:0030881 | | beta-2-microglobulin binding | | Interacting selectively and non-covalently with beta-2-microglobulin. |
| GO:0046703 | | natural killer cell lectin-like receptor binding | | Interacting selectively and non-covalently with a lectin-like natural killer cell receptor. |
| 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). |
biological process |
| GO:0001913 | | T cell mediated cytotoxicity | | The directed killing of a target cell by a T cell through the release of granules containing cytotoxic mediators or through the engagement of death receptors. |
| 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:0006974 | | cellular response to DNA damage stimulus | | Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus indicating damage to its DNA from environmental insults or errors during metabolism. |
| GO:0019835 | | cytolysis | | The rupture of cell membranes and the loss of cytoplasm. |
| GO:0042742 | | defense response to bacterium | | Reactions triggered in response to the presence of a bacterium that act to protect the cell or organism. |
| GO:0051607 | | defense response to virus | | Reactions triggered in response to the presence of a virus that act to protect the cell or organism. |
| GO:0046629 | | gamma-delta T cell activation | | The change in morphology and behavior of a gamma-delta T cell resulting from exposure to a mitogen, cytokine, chemokine, cellular ligand, or an antigen for which it is specific. |
| GO:0006955 | | immune response | | Any immune system process that functions in the calibrated response of an organism to a potential internal or invasive threat. |
| GO:0002418 | | immune response to tumor cell | | An immune system process that functions in the response of an organism to a tumor cell. |
| 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:0042267 | | natural killer cell mediated cytotoxicity | | The directed killing of a target cell by a natural killer cell through the release of granules containing cytotoxic mediators or through the engagement of death receptors. |
| GO:0032815 | | negative regulation of natural killer cell activation | | Any process that stops, prevents, or reduces the frequency, rate or extent of natural killer cell activation. |
| GO:0045953 | | negative regulation of natural killer cell mediated cytotoxicity | | Any process that stops, prevents, or reduces the rate of natural killer mediated cytotoxicity. |
| GO:0050776 | | regulation of immune response | | Any process that modulates the frequency, rate or extent of the immune response, the immunological reaction of an organism to an immunogenic stimulus. |
| GO:0009408 | | response to heat | | Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a heat stimulus, a temperature stimulus above the optimal temperature for that organism. |
| 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:0009986 | | cell surface | | The external part of the cell wall and/or plasma membrane. |
| GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| GO:0005615 | | extracellular space | | That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid. |
| 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. |
