molecular function |
| GO:0042169 | | SH2 domain binding | | Interacting selectively and non-covalently with a SH2 domain (Src homology 2) of a protein, a protein domain of about 100 amino-acid residues and belonging to the alpha + beta domain class. |
| GO:0017124 | | SH3 domain binding | | Interacting selectively and non-covalently with a SH3 domain (Src homology 3) of a protein, small protein modules containing approximately 50 amino acid residues found in a great variety of intracellular or membrane-associated proteins. |
| GO:0005070 | | SH3/SH2 adaptor activity | | Interacting selectively and non-covalently and simultaneously with one or more signal transduction molecules, usually acting as a scaffold to bring these molecules into close proximity either using their own SH2/SH3 domains (e.g. Grb2) or those of their target molecules (e.g. SAM68). |
| 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:0019901 | | protein kinase binding | | Interacting selectively and non-covalently with a protein kinase, any enzyme that catalyzes the transfer of a phosphate group, usually from ATP, to a protein substrate. |
| GO:0019903 | | protein phosphatase binding | | Interacting selectively and non-covalently with any protein phosphatase. |
biological process |
| GO:0050852 | | T cell receptor signaling pathway | | A series of molecular signals initiated by the cross-linking of an antigen receptor on a T cell. |
| 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: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:0045785 | | positive regulation of cell adhesion | | Any process that activates or increases the frequency, rate or extent of cell adhesion. |
| GO:0009967 | | positive regulation of signal transduction | | Any process that activates or increases the frequency, rate or extent of signal transduction. |
| GO:0045944 | | positive regulation of transcription from RNA polymerase II promoter | | Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter. |
| GO:0045893 | | positive regulation of transcription, DNA-templated | | Any process that activates or increases the frequency, rate or extent of cellular DNA-templated transcription. |
| GO:0072659 | | protein localization to plasma membrane | | A process in which a protein is transported to, or maintained in, a specific location in the plasma membrane. |
cellular component |
| GO:0042101 | | T cell receptor complex | | A protein complex that contains a disulfide-linked heterodimer of T cell receptor (TCR) chains, which are members of the immunoglobulin superfamily, and mediates antigen recognition, ultimately resulting in T cell activation. The TCR heterodimer is associated with the CD3 complex, which consists of the nonpolymorphic polypeptides gamma, delta, epsilon, zeta, and, in some cases, eta (an RNA splice variant of zeta) or Fc epsilon chains. |
| GO:0005911 | | cell-cell junction | | A cell junction that forms a connection between two or more cells in a multicellular organism; excludes direct cytoplasmic junctions such as ring canals. |
| GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| GO:0005829 | | cytosol | | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. |
| GO:0016020 | | membrane | | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
| GO:0005634 | | nucleus | | A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. |
| 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. |
