|
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:0008152
|
metabolic process
|
The chemical reactions and pathways, including anabolism and catabolism, by which living organisms transform chemical substances. Metabolic processes typically transform small molecules, but also include macromolecular processes such as DNA repair and replication, and protein synthesis and degradation. |
GO:0006952
|
defense response
|
Reactions, triggered in response to the presence of a foreign body or the occurrence of an injury, which result in restriction of damage to the organism attacked or prevention/recovery from the infection caused by the attack. |
GO:0009607
|
response to biotic stimulus
|
Any process that results in 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 biotic stimulus, a stimulus caused or produced by a living organism. |
GO:0044237
|
cellular metabolic process
|
The chemical reactions and pathways by which individual cells transform chemical substances. |
GO:0016567

protein ubiquitination
|
The process in which one or more ubiquitin groups are added to a protein. |
GO:0006950
|
response to stress
|
Any process that results in 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 disturbance in organismal or cellular homeostasis, usually, but not necessarily, exogenous (e.g. temperature, humidity, ionizing radiation). |
GO:0035556
|
intracellular signal transduction
|
The process in which a signal is passed on to downstream components within the cell, which become activated themselves to further propagate the signal and finally trigger a change in the function or state of the cell. |
GO:0019538
|
protein metabolic process
|
The chemical reactions and pathways involving a specific protein, rather than of proteins in general. Includes protein modification. |
GO:0006464
|
cellular protein modification process
|
The covalent alteration of one or more amino acids occurring in proteins, peptides and nascent polypeptides (co-translational, post-translational modifications) occurring at the level of an individual cell. Includes the modification of charged tRNAs that are destined to occur in a protein (pre-translation modification). |
GO:0071704
|
organic substance metabolic process
|
The chemical reactions and pathways involving an organic substance, any molecular entity containing carbon. |
GO:0009966
|
regulation of signal transduction
|
Any process that modulates the frequency, rate or extent of signal transduction. |
GO:0006955
|
immune response
|
Any immune system process that functions in the calibrated response of an organism to a potential internal or invasive threat. |
GO:0043412
|
macromolecule modification
|
The covalent alteration of one or more monomeric units in a polypeptide, polynucleotide, polysaccharide, or other biological macromolecule, resulting in a change in its properties. |
GO:0044238
|
primary metabolic process
|
The chemical reactions and pathways involving those compounds which are formed as a part of the normal anabolic and catabolic processes. These processes take place in most, if not all, cells of the organism. |
GO:0031347
|
regulation of defense response
|
Any process that modulates the frequency, rate or extent of a defense response. |
GO:0051716
|
cellular response to stimulus
|
Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus. The process begins with detection of the stimulus by a cell and ends with a change in state or activity or the cell. |
GO:0044260
|
cellular macromolecule metabolic process
|
The chemical reactions and pathways involving macromolecules, any molecule of high relative molecular mass, the structure of which essentially comprises the multiple repetition of units derived, actually or conceptually, from molecules of low relative molecular mass, as carried out by individual cells. |
GO:0016032
|
viral process
|
A multi-organism process in which a virus is a participant. The other participant is the host. Includes infection of a host cell, replication of the viral genome, and assembly of progeny virus particles. In some cases the viral genetic material may integrate into the host genome and only subsequently, under particular circumstances, 'complete' its life cycle. |
GO:0030683
|
evasion or tolerance by virus of host immune response
|
Any process, either active or passive, by which a virus avoids the effects of the host organism's immune response. The host is defined as the larger of the organisms involved in a symbiotic interaction. |
GO:0007154
|
cell communication
|
Any process that mediates interactions between a cell and its surroundings. Encompasses interactions such as signaling or attachment between one cell and another cell, between a cell and an extracellular matrix, or between a cell and any other aspect of its environment. |
GO:0045087
|
innate immune response
|
Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens. |
GO:0044267
|
cellular protein metabolic process
|
The chemical reactions and pathways involving a specific protein, rather than of proteins in general, occurring at the level of an individual cell. Includes cellular protein modification. |
GO:0009987
|
cellular 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. |
