molecular function |
| GO:0051537 | | 2 iron, 2 sulfur cluster binding | | Interacting selectively and non-covalently with a 2 iron, 2 sulfur (2Fe-2S) cluster; this cluster consists of two iron atoms, with two inorganic sulfur atoms found between the irons and acting as bridging ligands. |
| GO:0008794 | | arsenate reductase (glutaredoxin) activity | | Catalysis of the reaction: arsenate + reduced glutaredoxin = arsenite + oxidized glutaredoxin. Glutaredoxin functions as the electron donor for arsenate reduction. The electron flow therefore is ( NADPH -> glutathione reductase (EC:1.6.4.2) -> ) glutathione -> glutaredoxin -> arsenate reductase, i.e. glutathione is reduced by glutathione reductase and glutaredoxin is reduced by glutathione. |
| GO:0009055 | | electron carrier activity | | Any molecular entity that serves as an electron acceptor and electron donor in an electron transport chain. An electron transport chain is a process in which a series of electron carriers operate together to transfer electrons from donors to any of several different terminal electron acceptors to generate a transmembrane electrochemical gradient. |
| GO:0015038 | | glutathione disulfide oxidoreductase activity | | Catalysis of the reaction: 2 glutathione + electron acceptor = glutathione disulfide + electron donor. |
| GO:0051536 | | iron-sulfur cluster binding | | Interacting selectively and non-covalently with an iron-sulfur cluster, a combination of iron and sulfur atoms. |
| GO:0046872 | | metal ion binding | | Interacting selectively and non-covalently with any metal ion. |
| GO:0003756 | | protein disulfide isomerase activity | | Catalysis of the rearrangement of both intrachain and interchain disulfide bonds in proteins. |
| GO:0015035 | | protein disulfide oxidoreductase activity | | Catalysis of the reaction: a protein with reduced sulfide groups = a protein with oxidized disulfide bonds. |
biological process |
| GO:0042262 | | DNA protection | | Any process in which DNA is protected from damage by, for example, oxidative stress. |
| GO:0007568 | | aging | | A developmental process that is a deterioration and loss of function over time. Aging includes loss of functions such as resistance to disease, homeostasis, and fertility, as well as wear and tear. Aging includes cellular senescence, but is more inclusive. May precede death and may succeed developmental maturation (GO:0021700). |
| GO:0006915 | | apoptotic process | | A programmed cell death process which begins when a cell receives an internal (e.g. DNA damage) or external signal (e.g. an extracellular death ligand), and proceeds through a series of biochemical events (signaling pathway phase) which trigger an execution phase. The execution phase is the last step of an apoptotic process, and is typically characterized by rounding-up of the cell, retraction of pseudopodes, reduction of cellular volume (pyknosis), chromatin condensation, nuclear fragmentation (karyorrhexis), plasma membrane blebbing and fragmentation of the cell into apoptotic bodies. When the execution phase is completed, the cell has died. |
| GO:0030154 | | cell differentiation | | The process in which relatively unspecialized cells, e.g. embryonic or regenerative cells, acquire specialized structural and/or functional features that characterize the cells, tissues, or organs of the mature organism or some other relatively stable phase of the organism's life history. Differentiation includes the processes involved in commitment of a cell to a specific fate and its subsequent development to the mature state. |
| GO:0045454 | | cell redox homeostasis | | Any process that maintains the redox environment of a cell or compartment within a cell. |
| GO:0071451 | | cellular response to superoxide | | 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 superoxide stimulus. Superoxide is the anion, oxygen-, formed by addition of one electron to dioxygen (O2) or any compound containing the superoxide anion. |
| GO:0006749 | | glutathione metabolic process | | The chemical reactions and pathways involving glutathione, the tripeptide glutamylcysteinylglycine, which acts as a coenzyme for some enzymes and as an antioxidant in the protection of sulfhydryl groups in enzymes and other proteins; it has a specific role in the reduction of hydrogen peroxide (H2O2) and oxidized ascorbate, and it participates in the gamma-glutamyl cycle. |
| 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:0009966 | | regulation of signal transduction | | Any process that modulates the frequency, rate or extent of signal transduction. |
| GO:0006355 | | regulation of transcription, DNA-templated | | Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription. |
| GO:0042542 | | response to hydrogen peroxide | | 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 hydrogen peroxide (H2O2) stimulus. |
| GO:0010033 | | response to organic substance | | 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 an organic substance stimulus. |
| GO:0051775 | | response to redox state | | 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 stimulus indicating redox state. Redox state refers to the balance of oxidized versus reduced forms of electron donors and acceptors in an organelle, cell or organ; plastoquinone, glutathione (GSH/GSSG), and nicotinamide nucleotides (NAD+/NADH and NADP+/NADPH) are among the most important. |
| GO:0009266 | | response to temperature 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 temperature stimulus. |
cellular component |
| GO:0030425 | | dendrite | | A neuron projection that has a short, tapering, often branched, morphology, receives and integrates signals from other neurons or from sensory stimuli, and conducts a nerve impulse towards the axon or the cell body. In most neurons, the impulse is conveyed from dendrites to axon via the cell body, but in some types of unipolar neuron, the impulse does not travel via the cell body. |
| GO:0043231 | | intracellular membrane-bounded organelle | | Organized structure of distinctive morphology and function, bounded by a single or double lipid bilayer membrane and occurring within the cell. Includes the nucleus, mitochondria, plastids, vacuoles, and vesicles. Excludes the plasma membrane. |
| 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. |
| GO:0043025 | | neuronal cell body | | The portion of a neuron that includes the nucleus, but excludes cell projections such as axons and dendrites. |
| GO:0005654 | | nucleoplasm | | That part of the nuclear content other than the chromosomes or the nucleolus. |
| 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. |
