molecular function
    GO:0004033    aldo-keto reductase (NADP) activity    Catalysis of the reaction: an alcohol + NADP+ = an aldehyde or a ketone + NADPH + H+.
    GO:0044325    ion channel binding    Interacting selectively and non-covalently with one or more specific sites on an ion channel, a protein complex that spans a membrane and forms a water-filled channel across the phospholipid bilayer allowing selective ion transport down its electrochemical gradient.
    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:0015459    potassium channel regulator activity    Modulates potassium channel activity via direct interaction interaction with a potassium channel (binding or modification).
    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:0005244    voltage-gated ion channel activity    Enables the transmembrane transfer of an ion by a voltage-gated channel. An ion is an atom or group of atoms carrying an electric charge by virtue of having gained or lost one or more electrons. A voltage-gated channel is a channel whose open state is dependent on the voltage across the membrane in which it is embedded.
    GO:0005249    voltage-gated potassium channel activity    Enables the transmembrane transfer of a potassium ion by a voltage-gated channel. A voltage-gated channel is a channel whose open state is dependent on the voltage across the membrane in which it is embedded.
biological process
    GO:0070995    NADPH oxidation    A metabolic process that results in the oxidation of reduced nicotinamide adenine dinucleotide, NADPH, to the oxidized form, NADP.
    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:0045445    myoblast differentiation    The process in which a relatively unspecialized cell acquires specialized features of a myoblast. A myoblast is a mononucleate cell type that, by fusion with other myoblasts, gives rise to the myotubes that eventually develop into striated muscle fibers.
    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:0071805    potassium ion transmembrane transport    A process in which a potassium ion is transported from one side of a membrane to the other.
    GO:0006813    potassium ion transport    The directed movement of potassium ions (K+) into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
    GO:0051291    protein heterooligomerization    The process of creating protein oligomers, compounds composed of a small number, usually between three and ten, of component monomers that are not all identical.
