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:0046873 metal ion transmembrane transporter activity Enables the transfer of metal ions 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: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.
