molecular function |
| GO:0005509 | | calcium ion binding | | Interacting selectively and non-covalently with calcium ions (Ca2+). |
| GO:0046872 | | metal ion binding | | Interacting selectively and non-covalently with any metal ion. |
| GO:0022829 | | wide pore channel activity | | Enables the transport of a solute across a membrane via a large pore, un-gated channel. Examples include gap junctions, which transport substances from one cell to another; and porins which transport substances in and out of bacteria, mitochondria and chloroplasts. |
biological process |
| GO:0019835 | | cytolysis | | The rupture of cell membranes and the loss of cytoplasm. |
| GO:0002357 | | defense response to tumor cell | | Reactions triggered in response to the presence of a tumor cell 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:0002418 | | immune response to tumor cell | | An immune system process that functions in the response of an organism to a tumor cell. |
| GO:0001771 | | immunological synapse formation | | The formation of an area of close contact between a lymphocyte (T-, B-, or natural killer cell) and a target cell through the clustering of particular signaling and adhesion molecules and their associated membrane rafts on both the lymphocyte and target cell, which facilitates activation of the lymphocyte, transfer of membrane from the target cell to the lymphocyte, and in some situations killing of the target cell through release of secretory granules and/or death-pathway ligand-receptor interaction. |
| GO:0051260 | | protein homooligomerization | | The process of creating protein oligomers, compounds composed of a small number, usually between three and ten, of identical component monomers. Oligomers may be formed by the polymerization of a number of monomers or the depolymerization of a large protein polymer. |
| GO:0055085 | | transmembrane transport | | The process in which a solute is transported across a lipid bilayer, from one side of a membrane to the other |
cellular component |
| GO:0044194 | | cytolytic granule | | A specialized secretory lysosome that is present in cells with cytolytic capability such as cytotoxic T lymphocytes and natural killer cells. Cytolytic granules mediate the storage and regulated excretion of lytic molecules for killing of target cells. |
| GO:0005768 | | endosome | | A vacuole to which materials ingested by endocytosis are delivered. |
| GO:0031904 | | endosome lumen | | The volume enclosed by the membrane of an endosome. |
| 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: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. |
