GO Term : GO:0015467 G-protein activated inward rectifier potassium channel activity GO
Namespace:  molecular_function Obsolete:  false
description  Enables the transmembrane transfer of a potassium ion by an inwardly-rectifying voltage-gated channel, where the inward rectification is due to a voltage-dependent block of the channel pore by a G protein. An inwardly rectifying current-voltage relation is one where at any given driving force the inward flow of K+ ions exceeds the outward flow for the opposite driving force.

GO:0006810 transport The directed movement of substances (such as macromolecules, small molecules, ions) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter or pore.
GO:0055085 transmembrane transport The process in which a solute is transported across a lipid bilayer, from one side of a membrane to the other
GO:0006812 cation transport The directed movement of cations, atoms or small molecules with a net positive charge, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
GO:0022857 transmembrane transporter activity Enables the transfer of a substance from one side of a membrane to the other.
GO:0015079 potassium ion transmembrane transporter activity Enables the transfer of potassium ions (K+) from one side of a membrane to the other.
GO:0071805 potassium ion transmembrane transport A process in which a potassium ion is transported 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: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: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:0006811 ion transport The directed movement of charged atoms or small charged molecules into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
GO:0030001 metal ion transport The directed movement of metal ions, any metal ion with an electric charge, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
GO:0005242 inward rectifier potassium channel activity Enables the transmembrane transfer of a potassium ion by an inwardly-rectifying voltage-gated channel. An inwardly rectifying current-voltage relation is one where at any given driving force the inward flow of K+ ions exceeds the outward flow for the opposite driving force. The inward-rectification is due to a voltage-dependent block of the channel pore by a specific ligand or ligands, and as a result the macroscopic conductance depends on the difference between membrane voltage and the K+ equilibrium potential rather than on membrane voltage itself.
GO:0006813 potassium ion transport The directed movement of potassium ions (K+) into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

GO:0005267 potassium channel activity Enables the selective, facilitated diffusion of a potassium ion (by an energy-independent process) involving passage through a transmembrane aqueous pore or channel without evidence for a carrier-mediated mechanism.
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:0005249 voltage-gated potassium channel activity Enables the transmembrane transfer of a potassium ion by a voltage-gated channel. A voltage-gated channel is a channel whose open state is dependent on the voltage across the membrane in which it is embedded.
GO:0005261 cation channel activity Enables the selective, energy-independent passage of cations across a lipid bilayer down a concentration gradient.
GO:0015672 monovalent inorganic cation transport The directed movement of inorganic cations with a valency of one into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. Inorganic cations are atoms or small molecules with a positive charge which do not contain carbon in covalent linkage.
GO:0098655 cation transmembrane transport A process in which a cation is transported from one side of a membrane to the other by means of some agent such as a transporter or pore.
GO:0009987 cellular process Any process that is carried out at the cellular level, but not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level.
GO:0022843 voltage-gated cation channel activity Enables the transmembrane transfer of a cation by a voltage-gated channel. A cation is a positively charged ion. A voltage-gated channel is a channel whose open state is dependent on the voltage across the membrane in which it is embedded.
GO:0034765 regulation of ion transmembrane transport Any process that modulates the frequency, rate or extent of the directed movement of ions from one side of a membrane to the other.
