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: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: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: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. |
GO:0008381
|
mechanically-gated ion channel activity
|
Enables the transmembrane transfer of an ion by a channel that opens in response to a mechanical stress. |
GO:0022833
|
mechanically gated channel activity
|
Enables the transmembrane transfer of a solute by a channel that opens in response to a mechanical stress. |
GO:0043854
|
cyclic nucleotide-gated mechanosensitive ion channel activity
|
Enables the transmembrane transfer of an ion by a channel that opens in response to a mechanical stress and when a cyclic nucleotide has been bound by the channel complex or one of its constituent parts. |
