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:0050839 | | cell adhesion molecule binding | | Interacting selectively and non-covalently with a cell adhesion molecule. |
| GO:0046872 | | metal ion binding | | Interacting selectively and non-covalently with any metal ion. |
| 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). |
| GO:0032403 | | protein complex binding | | Interacting selectively and non-covalently with any protein complex (a complex of two or more proteins that may include other nonprotein molecules). |
| GO:0046982 | | protein heterodimerization activity | | Interacting selectively and non-covalently with a nonidentical protein to form a heterodimer. |
biological process |
| GO:0002291 | | T cell activation via T cell receptor contact with antigen bound to MHC molecule on antigen presenting cell | | The change in morphology and behavior of a mature or immature T cell resulting from exposure to an antigen for which its T cell receptor is specific bound to an MHC molecule on an antigen presenting cell, leading to the initiation or perpetuation of an immune response. |
| GO:0007155 | | cell adhesion | | The attachment of a cell, either to another cell or to an underlying substrate such as the extracellular matrix, via cell adhesion molecules. |
| GO:0007160 | | cell-matrix adhesion | | The binding of a cell to the extracellular matrix via adhesion molecules. |
| GO:0030198 | | extracellular matrix organization | | A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of an extracellular matrix. |
| GO:0007157 | | heterophilic cell-cell adhesion via plasma membrane cell adhesion molecules | | The attachment of an adhesion molecule in one cell to a nonidentical adhesion molecule in an adjacent cell. |
| GO:0006954 | | inflammatory response | | The immediate defensive reaction (by vertebrate tissue) to infection or injury caused by chemical or physical agents. The process is characterized by local vasodilation, extravasation of plasma into intercellular spaces and accumulation of white blood cells and macrophages. |
| GO:0007229 | | integrin-mediated signaling pathway | | A series of molecular signals initiated by the binding of extracellular ligand to an integrin on the surface of a target cell, and ending with regulation of a downstream cellular process, e.g. transcription. |
| GO:0007159 | | leukocyte cell-cell adhesion | | The attachment of a leukocyte to another cell via adhesion molecules. |
| GO:0050900 | | leukocyte migration | | The movement of a leukocyte within or between different tissues and organs of the body. |
| GO:0006928 | | movement of cell or subcellular component | | The directed, self-propelled movement of a cell or subcellular component without the involvement of an external agent such as a transporter or a pore. |
| GO:0043113 | | receptor clustering | | The receptor metabolic process that results in grouping of a set of receptors at a cellular location, often to amplify the sensitivity of a signaling response. |
| 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:0007165 | | signal transduction | | The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell. |
| GO:0016337 | | single organismal cell-cell adhesion | | The attachment of one cell to another cell via adhesion molecules, where both cells are part of the same organism. |
cellular component |
| GO:0009986 | | cell surface | | The external part of the cell wall and/or plasma membrane. |
| GO:0070062 | | extracellular exosome | | A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm. |
| 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:0034687 | | integrin alphaL-beta2 complex | | An integrin complex that comprises one alphaL subunit and one beta2 subunit. |
| GO:0008305 | | integrin complex | | A protein complex that is composed of one alpha subunit and one beta subunit, both of which are members of the integrin superfamily of cell adhesion receptors; the complex spans the plasma membrane and binds to extracellular matrix ligands, cell-surface ligands, and soluble ligands. |
| 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. |
