| GO:0006821 | chloride transport | biological_process | The directed movement of chloride into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. [GOC:krc] |
| GO:0022803 | passive transmembrane transporter activity | molecular_function | Enables the transfer of a single solute from one side of a membrane to the other by a mechanism involving conformational change, either by facilitated diffusion or in a membrane potential dependent process if the solute is charged. [GOC:mtg_transport, ISBN:0815340729] |
| GO:0005216 | ion channel activity | molecular_function | 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:0015103 | inorganic anion transmembrane transporter activity | molecular_function | Enables the transfer of inorganic anions from one side of a membrane to the other. Inorganic anions are atoms or small molecules with a negative charge which do not contain carbon in covalent linkage. [GOC:ai] |
| GO:0005254 | chloride channel activity | molecular_function | Enables the facilitated diffusion of a chloride (by an energy-independent process) involving passage through a transmembrane aqueous pore or channel without evidence for a carrier-mediated mechanism.

| GO:0008509 | anion transmembrane transporter activity | molecular_function | Enables the transfer of a negatively charged ion from one side of a membrane to the other. [GOC:dgf, GOC:mtg_transport, ISBN:0815340729] |
| GO:0005215 | transporter activity | molecular_function | Enables the directed movement of substances (such as macromolecules, small molecules, ions) into, out of or within a cell, or between cells. [GOC:ai, GOC:dgf] |
| GO:0005515 | protein binding | molecular_function | Binding to a protein. [GOC:go_curators] |
| GO:0022836 | gated channel activity | molecular_function | Enables the transmembrane transfer of a solute by a channel that opens in response to a specific stimulus. [GOC:mtg_transport] |
| GO:1902495 | transmembrane transporter complex | cellular_component | A transmembrane protein complex which enables the transfer of a substance from one side of a membrane to the other. [GOC:bhm, GOC:TermGenie, PMID:18024586] |
| GO:0015075 | ion transmembrane transporter activity | molecular_function | Enables the transfer of an ion from one side of a membrane to the other. [GOC:dgf, GOC:mtg_transport, ISBN:0815340729] |
| GO:0015267 | channel activity | molecular_function | 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. [GOC:mtg_transport, ISBN:0815340729] |
| GO:0022857 | transmembrane transporter activity | molecular_function | Enables the transfer of a substance, usually a specific substance or a group of related substances, from one side of a membrane to the other. [GOC:jid, GOC:mtg_transport, ISBN:0815340729] |
| GO:0034702 | ion channel complex | cellular_component | A protein complex that spans a membrane and forms a water-filled channel across the phospholipid bilayer allowing selective ion transport down its electrochemical gradient. [GOC:mah, ISBN:071673706X] |
| GO:0005887 | integral component of plasma membrane | cellular_component | The component of the plasma 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. [GOC:dos, GOC:go_curators] |
| GO:0032991 | protein-containing complex | cellular_component | A stable assembly of two or more macromolecules, i.e. proteins, nucleic acids, carbohydrates or lipids, in which at least one component is a protein and the constituent parts function together. [GOC:dos, GOC:mah] |
