| Identifier | Name | Description |
|---|---|---|
| GO:0022857 | transmembrane transporter activity | Enables the transfer of a substance 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: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:0000269 | toxin export channel activity | Enables the energy independent passage of toxins, sized less than 1000 Da, across a membrane towards the outside of the cell. The transmembrane portions of porins consist exclusively of beta-strands which form a beta-barrel. They are found in the outer membranes of Gram-negative bacteria, mitochondria, plastids and possibly acid-fast Gram-positive bacteria. |
| GO:0015288 | porin activity | Catalysis of the transfer of substances, sized less than 1000 Da, from one side of the membrane to the other. The transmembrane portions of porins consist exclusively of beta-strands which form a beta-barrel. They are found in the outer membranes of Gram-negative bacteria, mitochondria, plastids and possibly acid-fast Gram-positive bacteria. |
| GO:0019534 | toxin transporter activity | Enables the directed movement of a toxin into, out of or within a cell, or between cells. A toxin is a poisonous compound (typically a protein) that is produced by cells or organisms and that can cause disease when introduced into the body or tissues of an organism. |
| 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:0022829 | wide pore channel activity | Enables the transport of a solute across a membrane via a large pore, un-gated channel. Examples include gap junctions, which transport substances from one cell to another; and porins which transport substances in and out of bacteria, mitochondria and chloroplasts. |
| 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. |
