| GO:0002250 | adaptive immune response | biological_process | 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_REF:0000022, GOC:add, ISBN:0781735149] |
| GO:0002768 | immune response-regulating cell surface receptor signaling pathway | biological_process | A series of molecular signals initiated by the binding of an extracellular ligand to a receptor on the surface of the target cell capable of activating, perpetuating, or inhibiting an immune response. [GOC:add, ISBN:0781735149, PMID:15771571] |
| GO:0006955 | immune response | biological_process | Any immune system process that functions in the calibrated response of an organism to a potential internal or invasive threat. [GO_REF:0000022, GOC:add] |
| GO:0007166 | cell surface receptor signaling pathway | biological_process | A series of molecular signals initiated by activation of a receptor on the surface of a cell. The pathway begins with binding of an extracellular ligand to a cell surface receptor, or for receptors that signal in the absence of a ligand, by ligand-withdrawal or the activity of a constitutively active receptor. The pathway ends with regulation of a downstream cellular process, e.g. transcription. [GOC:bf, GOC:mah, GOC:pr, GOC:signaling] |
| GO:0048583 | regulation of response to stimulus | biological_process | Any process that modulates the frequency, rate or extent of a response to a stimulus. Response to stimulus is 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 stimulus. [GOC:jid] |
| GO:0002764 | immune response-regulating signaling pathway | biological_process | The cascade of processes by which a signal interacts with a receptor, causing a change in the level or activity of a second messenger or other downstream target, and ultimately leading to the activation, perpetuation, or inhibition of an immune response. [GOC:add, ISBN:0781735149, PMID:15771571] |
| GO:0098588 | bounding membrane of organelle | cellular_component | The lipid bilayer that forms the outer-most layer of an organelle. [GOC:dos] |
| GO:0038023 | signaling receptor activity | molecular_function | Receiving a signal and transmitting it in the cell to initiate a change in cell activity. A signal is a physical entity or change in state that is used to transfer information in order to trigger a response. [GOC:bf, GOC:signaling] |

| GO:0050794 | regulation of cellular process | biological_process | Any process that modulates the frequency, rate or extent of a cellular process, any of those that are carried out at the cellular level, but are not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level. [GOC:go_curators] |
| GO:0030662 | coated vesicle membrane | cellular_component | The lipid bilayer surrounding a coated vesicle. [GOC:mah] |
| GO:0010008 | endosome membrane | cellular_component | The lipid bilayer surrounding an endosome. [GOC:mah] |
| GO:0004888 | transmembrane signaling receptor activity | molecular_function | Combining with an extracellular or intracellular signal and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity or state as part of signal transduction. [GOC:go_curators, Wikipedia:Transmembrane_receptor] |
| GO:0044877 | protein-containing complex binding | molecular_function | Binding to a macromolecular complex. [GOC:jl] |
| GO:0050776 | regulation of immune response | biological_process | Any process that modulates the frequency, rate or extent of the immune response, the immunological reaction of an organism to an immunogenic stimulus. [GOC:ai] |
| GO:0005887 | integral component of plasma membrane | cellular_component | 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. [GOC:dos, GOC:go_curators] |
| GO:0031090 | organelle membrane | cellular_component | A membrane that is one of the two lipid bilayers of an organelle envelope or the outermost membrane of single membrane bound organelle. [GOC:dos, GOC:mah] |
| GO:0050789 | regulation of biological process | biological_process | Any process that modulates the frequency, rate or extent of a biological process. Biological processes are regulated by many means; examples include the control of gene expression, protein modification or interaction with a protein or substrate molecule. [GOC:ai, GOC:go_curators] |
| GO:0012506 | vesicle membrane | cellular_component | The lipid bilayer surrounding any membrane-bounded vesicle in the cell. [GOC:mah, GOC:vesicle] |
| GO:0007165 | signal transduction | biological_process | 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. [GOC:go_curators, GOC:mtg_signaling_feb11] |
| GO:0009987 | cellular process | biological_process | Any process that is carried out at the cellular level, but not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level. [GOC:go_curators, GOC:isa_complete] |

Or, a substance produced by a cellular organism with granularity above the level of a protein complex. [GOC:kmv] |
