| Identifier | Name | Description |
|---|---|---|
| GO:0022857 | transmembrane transporter activity | Enables the transfer of a substance from one side of a membrane to the other. |
| GO:0022891 | substrate-specific transmembrane transporter activity | Enables the transfer of a specific substance or group of related substances from one side of a membrane to the other. |
| GO:0005215 | transporter activity | Enables the directed movement of substances (such as macromolecules, small molecules, ions) into, out of or within a cell, or between cells. |
| 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:0008324 | cation transmembrane transporter activity | Enables the transfer of cation from one side of the membrane to the other. |
| GO:0015075 | ion transmembrane transporter activity | Enables the transfer of an ion from one side of a membrane to the other. |
| GO:0003674 | molecular_function | Elemental activities, such as catalysis or binding, describing the actions of a gene product at the molecular level. A given gene product may exhibit one or more molecular functions. |
| GO:0022892 | substrate-specific transporter activity | Enables the directed movement of a specific substance or group of related substances (such as macromolecules, small molecules, ions) into, out of or within a cell, or between cells. |
| GO:0022803 | passive transmembrane transporter activity | Enables the transfer of a solute from one side of the membrane to the other, down the solute's concentration gradient. |
| GO:0015267 | channel activity | Enables the energy-independent facilitated diffusion, mediated by passage of a solute through a transmembrane aqueous pore or channel. Stereospecificity is not exhibited but this transport may be specific for a particular molecular species or class of molecules. |
| GO:0005261 | cation channel activity | Enables the selective, energy-independent passage of cations across a lipid bilayer down a concentration gradient. |
| GO:0022834 | ligand-gated channel activity | Enables the transmembrane transfer of a solute by a channel that opens when a specific ligand has been bound by the channel complex or one of its constituent parts. |
| GO:0022836 | gated channel activity | Enables the transmembrane transfer of a solute by a channel that opens in response to a specific stimulus. |
| GO:0022838 | substrate-specific channel activity | Enables the energy-independent facilitated diffusion, mediated by passage of a specific solute through a transmembrane aqueous pore or channel. Stereospecificity is not exhibited but this transport may be specific for a particular molecular species or class of molecules. |
| GO:0015276 | ligand-gated ion channel activity | Enables the transmembrane transfer of an ion by a channel that opens when a specific ligand has been bound by the channel complex or one of its constituent parts. |
| GO:0005217 | intracellular ligand-gated ion channel activity | Enables the transmembrane transfer of an ion by a channel that opens when a specific intracellular ligand has been bound by the channel complex or one of its constituent parts. |
| GO:0005221 | intracellular cyclic nucleotide activated cation channel activity | Enables the transmembrane transfer of a cation by a channel that opens when intracellular cyclic nucleotide has been bound by the channel complex or one of its constituent parts. |
| 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. |
