| GO:0003674 | molecular_function | molecular_function | A molecular process that can be carried out by the action of a single macromolecular machine, usually via direct physical interactions with other molecular entities. Function in this sense denotes an action, or activity, that a gene product (or a complex) performs. [GOC:pdt] |
| GO:0008150 | biological_process | biological_process | A biological process is the execution of a genetically-encoded biological module or program. It consists of all the steps required to achieve the specific biological objective of the module. A biological process is accomplished by a particular set of molecular functions carried out by specific gene products (or macromolecular complexes), often in a highly regulated manner and in a particular temporal sequence. [GOC:pdt] |
| GO:0009986 | cell surface | cellular_component | The external part of the cell wall and/or plasma membrane. [GOC:jl, GOC:mtg_sensu, GOC:sm] |
| GO:0002373 | plasmacytoid dendritic cell cytokine production | biological_process | Any process that contributes to cytokine production by a plasmacytoid dendritic cell. [GOC:add, ISBN:0781735149] |
| GO:0009897 | external side of plasma membrane | cellular_component | The leaflet of the plasma membrane that faces away from the cytoplasm and any proteins embedded or anchored in it or attached to its surface. [GOC:dos, GOC:tb] |
| GO:0042110 | T cell activation | biological_process | The change in morphology and behavior of a mature or immature T cell resulting from exposure to a mitogen, cytokine, chemokine, cellular ligand, or an antigen for which it is specific. [GOC:mgi_curators, ISBN:0781735149] |
