| 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: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. |
