NMR Structure(hide GO term definitions)
Chain A   (GLRX1_HUMAN | P35754)
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:0015038    glutathione disulfide oxidoreductase activity    Catalysis of the reaction: 2 glutathione + electron acceptor = glutathione disulfide + electron donor.
    GO:0097573    glutathione oxidoreductase activity    Catalysis of the reaction: protein-S-S-glutathione + glutathione-SH = protein-SH + glutathione-S-S-glutathione.
    GO:0047485    protein N-terminus binding    Interacting selectively and non-covalently with a protein N-terminus, the end of any peptide chain at which the 2-amino (or 2-imino) function of a constituent amino acid is not attached in peptide linkage to another amino-acid residue.
    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:0045454    cell redox homeostasis    Any process that maintains the redox environment of a cell or compartment within a cell.
    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:0045838    positive regulation of membrane potential    Any process that activates or increases the frequency, rate or extent of establishment or extent of a membrane potential, the electric potential existing across any membrane arising from charges in the membrane itself and from the charges present in the media on either side of the membrane.
    GO:2000651    positive regulation of sodium ion transmembrane transporter activity    Any process that activates or increases the frequency, rate or extent of sodium ion transmembrane transporter activity.
    GO:0080058    protein deglutathionylation    The protein modification process in which a glutathione molecule is removed from a protein amino acid by breaking a disulfide linkage.
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.
