NMR Structure(hide GO term definitions)
Chain A   (PRRG_PRB01 | Q9F7P4)
molecular function
    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:0010461    light-activated ion channel activity    Enables the transmembrane transfer of an ion by a channel that opens in response to a light stimulus.
    GO:0009881    photoreceptor activity    The function of absorbing and responding to incidental electromagnetic radiation, particularly visible light. The response may involve a change in conformation.
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:0007602    phototransduction    The sequence of reactions within a cell required to convert absorbed photons into a molecular signal.
    GO:0018298    protein-chromophore linkage    The covalent or noncovalent attachment of a chromophore to a protein.
    GO:0015992    proton transport    The directed movement of protons (hydrogen ions) into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
    GO:0050896    response to stimulus    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 stimulus. The process begins with detection of the stimulus and ends with a change in state or activity or the cell or organism.
    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:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    GO:0005886    plasma membrane    The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
