molecular function
    GO:0016531    copper chaperone activity    Assists in the delivery of copper ions to target proteins or compartments.
    GO:0005507    copper ion binding    Interacting selectively and non-covalently with copper (Cu) ions.
    GO:0005375    copper ion transmembrane transporter activity    Catalysis of the transfer of copper (Cu) ions from one side of a membrane to the other.
    GO:0032767    copper-dependent 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), in the presence of copper.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0016530    metallochaperone activity    Assists in the delivery of metal ions to target proteins or compartments.
    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).
biological process
    GO:0006878    cellular copper ion homeostasis    Any process involved in the maintenance of an internal steady state of copper ions at the level of a cell.
    GO:0035434    copper ion transmembrane transport    The directed movement of copper cation across a membrane.
    GO:0006825    copper ion transport    The directed movement of copper (Cu) ions into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
    GO:0015680    intracellular copper ion transport    The directed movement of copper (Cu) ions within a cell.
    GO:0006811    ion transport    The directed movement of charged atoms or small charged molecules into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
    GO:0030001    metal ion transport    The directed movement of metal ions, any metal ion with an electric charge, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
    GO:0006979    response to oxidative 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 oxidative stress, a state often resulting from exposure to high levels of reactive oxygen species, e.g. superoxide anions, hydrogen peroxide (H2O2), and hydroxyl radicals.
    GO:0006810    transport    The directed movement of substances (such as macromolecules, small molecules, ions) or cellular components (such as complexes and organelles) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter, pore or motor protein.
cellular component
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
