| 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:0008519 | ammonium transmembrane transporter activity | Enables the transfer of ammonium from one side of a membrane to the other. Ammonium is the cation NH4+ which is formed from N2 by root-nodule bacteria in leguminous plants and is an excretory product in ammonotelic animals. |
| 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:0022890 | inorganic cation transmembrane transporter activity | Enables the transfer of inorganic cations from one side of a membrane to the other. Inorganic cations are atoms or small molecules with a positive charge that do not contain carbon in covalent linkage. |
| 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:0022804 | active transmembrane transporter activity | Catalysis of the transfer of a specific substance or related group of substances from one side of a membrane to the other, up the solute's concentration gradient. The transporter binds the solute and undergoes a series of conformational changes. Transport works equally well in either direction. |
| 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:0015077 | monovalent inorganic cation transmembrane transporter activity | Enables the transfer of a inorganic cations with a valency of one from one side of a membrane to the other. Inorganic cations are atoms or small molecules with a positive charge that do not contain carbon in covalent linkage. |
| GO:0005261 | cation channel activity | Enables the selective, energy-independent passage of cations across a lipid bilayer down a concentration gradient. |
| 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:0005275 | amine transmembrane transporter activity | Enables the transfer of amines, including polyamines, from one side of the membrane to the other. Amines are organic compounds that are weakly basic in character and contain an amino (-NH2) or substituted amino group. |
| GO:0015101 | organic cation transmembrane transporter activity | Enables the transfer of organic cations from one side of a membrane to the other. Organic cations are atoms or small molecules with a positive charge that contain carbon in covalent linkage. |
| GO:0015200 | methylammonium transmembrane transporter activity | Enables directed movement of methylammonium, CH3NH2, into, out of or within a cell, or between cells. |
| GO:0015251 | ammonium channel activity | Enables the selective, facilitated diffusion of ammonium (by an energy-independent process) involving passage through a transmembrane aqueous pore or channel without evidence for a carrier-mediated mechanism. |
| GO:0015264 | methylammonium channel activity | Enables the selective, facilitated diffusion of methylammonium (by an energy-independent process) involving passage through a transmembrane aqueous pore or channel without evidence for a carrier-mediated mechanism. Methylammonium is CH3NH2. |
