Asymmetric Unit(hide GO term definitions)
Chain A,B,C,D   (A8WHX9_DANRE | A8WHX9)
molecular function
    GO:0030551    cyclic nucleotide binding    Interacting selectively and non-covalently with a cyclic nucleotide, a nucleotide in which the phosphate group is in diester linkage to two positions on the sugar residue.
    GO:0043855    cyclic nucleotide-gated ion channel activity    Enables the transmembrane transfer of an ion by a channel that opens when a cyclic nucleotide has been bound by the channel complex or one of its constituent parts.
    GO:0005216    ion channel activity    Enables the facilitated diffusion of an ion (by an energy-independent process) by passage through a transmembrane aqueous pore or channel without evidence for a carrier-mediated mechanism. May be either selective (it enables passage of a specific ion only) or non-selective (it enables passage of two or more ions of same charge but different size).
    GO:0000155    phosphorelay sensor kinase activity    Catalysis of the phosphorylation of a histidine residue in response to detection of an extracellular signal such as a chemical ligand or change in environment, to initiate a change in cell state or activity. The two-component sensor is a histidine kinase that autophosphorylates a histidine residue in its active site. The phosphate is then transferred to an aspartate residue in a downstream response regulator, to trigger a response.
    GO:0005267    potassium channel activity    Enables the facilitated diffusion of a potassium ion (by an energy-independent process) involving passage through a transmembrane aqueous pore or channel without evidence for a carrier-mediated mechanism.
    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:0034220    ion transmembrane transport    A process in which an ion is transported from one side of a membrane to the other by means of some agent such as a transporter or pore.
    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:0000160    phosphorelay signal transduction system    A conserved series of molecular signals found in prokaryotes and eukaryotes; involves autophosphorylation of a histidine kinase and the transfer of the phosphate group to an aspartate that then acts as a phospho-donor to response regulator proteins.
    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:0042391    regulation of membrane potential    Any process that modulates the 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:0023014    signal transduction by protein phosphorylation    A process in which the transfer of one or more phosphate groups to a substrate transmits a signal to the phosphorylated substrate.
    GO:0055085    transmembrane transport    The process in which a solute is transported across a lipid bilayer, from one side of a membrane to the other
    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:0016021    integral component of membrane    The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
    GO:0005887    integral component of plasma membrane    The component of the plasma membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
    GO:0005622    intracellular    The living contents of a cell; the matter contained within (but not including) the plasma membrane, usually taken to exclude large vacuoles and masses of secretory or ingested material. In eukaryotes it includes the nucleus and cytoplasm.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
