| | GO:0042802 | | identical protein binding | | Interacting selectively and non-covalently with an identical protein or proteins. |
| | GO:0030145 | | manganese ion binding | | Interacting selectively and non-covalently with manganese (Mn) ions. |
| | GO:0046872 | | metal ion binding | | Interacting selectively and non-covalently with any metal ion. |
| | GO:0016491 | | oxidoreductase activity | | Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced. |
| | GO:0004784 | | superoxide dismutase activity | | Catalysis of the reaction: 2 superoxide + 2 H+ = O2 + hydrogen peroxide. |
| biological process |

| | GO:0003069 | | acetylcholine-mediated vasodilation involved in regulation of systemic arterial blood pressure | | The process in which acetylcholine signaling causes vasodilation, resulting in a change in blood pressure. |
| | GO:0001315 | | age-dependent response to reactive oxygen species | | 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 reactive oxygen species, where the change varies according to the age of the cell or organism. |
| | GO:0008285 | | negative regulation of cell proliferation | | Any process that stops, prevents or reduces the rate or extent of cell proliferation. |
| | GO:0043524 | | negative regulation of neuron apoptotic process | | Any process that stops, prevents, or reduces the frequency, rate or extent of cell death by apoptotic process in neurons. |
| | GO:1902176 | | negative regulation of oxidative stress-induced intrinsic apoptotic signaling pathway | | Any process that stops, prevents or reduces the frequency, rate or extent of an oxidative stress-induced intrinsic apoptotic signaling pathway. |
| | GO:0055114 | | oxidation-reduction process | | A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons. |
| | GO:0032364 | | oxygen homeostasis | | A homeostatic process involved in the maintenance of an internal steady state of oxygen within an organism or cell. |
| | GO:0051289 | | protein homotetramerization | | The formation of a protein homotetramer, a macromolecular structure consisting of four noncovalently associated identical subunits. |
| | GO:0008217 | | regulation of blood pressure | | Any process that modulates the force with which blood travels through the circulatory system. The process is controlled by a balance of processes that increase pressure and decrease pressure. |
| | GO:0006357 | | regulation of transcription from RNA polymerase II promoter | | Any process that modulates the frequency, rate or extent of transcription from an RNA polymerase II promoter. |
| | GO:0001836 | | release of cytochrome c from mitochondria | | The process that results in the movement of cytochrome c from the mitochondrial intermembrane space into the cytosol, which is part of the apoptotic signaling pathway and leads to caspase activation. |
| | GO:0019430 | | removal of superoxide radicals | | Any process, acting at the cellular level, involved in removing superoxide radicals (O2-) from a cell or organism, e.g. by conversion to dioxygen (O2) and hydrogen peroxide (H2O2). |
| | GO:0000302 | | response to reactive oxygen species | | 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 reactive oxygen species stimulus. Reactive oxygen species include singlet oxygen, superoxide, and oxygen free radicals. |
| | GO:0000303 | | response to superoxide | | 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 superoxide stimulus. Superoxide is the anion, oxygen-, formed by addition of one electron to dioxygen (O2) or any compound containing the superoxide anion. |
| | GO:0006801 | | superoxide metabolic process | | The chemical reactions and pathways involving superoxide, the superoxide anion O2- (superoxide free radical), or any compound containing this species. |
| cellular component |
|---|
| | 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:0005759 | | mitochondrial matrix | | The gel-like material, with considerable fine structure, that lies in the matrix space, or lumen, of a mitochondrion. It contains the enzymes of the tricarboxylic acid cycle and, in some organisms, the enzymes concerned with fatty acid oxidation. |
| | GO:0005739 | | mitochondrion | | A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration. |
