Chain A,B,C,D   (TRXR1_HUMAN | Q16881)
molecular function
    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:0050660    flavin adenine dinucleotide binding    Interacting selectively and non-covalently with FAD, flavin-adenine dinucleotide, the coenzyme or the prosthetic group of various flavoprotein oxidoreductase enzymes, in either the oxidized form, FAD, or the reduced form, FADH2.
    GO:0098626    methylseleninic acid reductase activity    Catalysis of the reaction: NADPH + H+ + CH3SeO2H => NADP+ + CH3SeOH + H2O.
    GO:0098625    methylselenol reductase activity    Catalysis of the reaction: NADPH + H+ + CH3SeOH => NADP+ + CH3SeH + H2O
    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:0016668    oxidoreductase activity, acting on a sulfur group of donors, NAD(P) as acceptor    Catalysis of an oxidation-reduction (redox) reaction in which a sulfur-containing group acts as a hydrogen or electron donor and reduces NAD or NADP.
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
    GO:0015035    protein disulfide oxidoreductase activity    Catalysis of the reaction: a protein with reduced sulfide groups = a protein with oxidized disulfide bonds.
    GO:0004791    thioredoxin-disulfide reductase activity    Catalysis of the reaction: NADP(+) + thioredoxin = H(+) + NADPH + thioredoxin disulfide.
biological process
    GO:0008283    cell proliferation    The multiplication or reproduction of cells, resulting in the expansion of a cell population.
    GO:0045454    cell redox homeostasis    Any process that maintains the redox environment of a cell or compartment within a cell.
    GO:0098869    cellular oxidant detoxification    Any process carried out at the cellular level that reduces or removes the toxicity superoxide radicals or hydrogen peroxide.
    GO:0007369    gastrulation    A complex and coordinated series of cellular movements that occurs at the end of cleavage during embryonic development of most animals. The details of gastrulation vary from species to species, but usually result in the formation of the three primary germ layers, ectoderm, mesoderm and endoderm.
    GO:0001707    mesoderm formation    The process that gives rise to the mesoderm. This process pertains to the initial formation of the structure from unspecified parts.
    GO:0015949    nucleobase-containing small molecule interconversion    The chemical reactions and pathways by which a nucleobase, nucleoside or nucleotide small molecule is synthesized from another nucleobase, nucleoside or nucleotide small molecule.
    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: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:0001887    selenium compound metabolic process    The chemical reactions and pathways involving compounds that contain selenium, such as selenocysteine.
    GO:0007165    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.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
    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: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: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.
