GO term | GO name | GO namespace | GO def |
GO:0005524 | ATP binding | molecular_function | Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator. [ISBN:0198506732] |
GO:0070089 | chloride-activated potassium channel activity | molecular_function | Enables the chloride concentration-regulatable energy-independent passage of potassium ions across a lipid bilayer down a concentration gradient. [GOC:kmv, GOC:mtg_transport] |
GO:0097623 | potassium ion export across plasma membrane | biological_process | The directed movement of potassium ions from inside of a cell, across the plasma membrane and into the extracellular region. [GOC:vw, PMID:11932440] |
GO:0005886 | plasma membrane | cellular_component | The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. [ISBN:0716731363] |
GO:0015271 | outward rectifier potassium channel activity | molecular_function | Enables the transmembrane transfer of a potassium ion by an outwardly-rectifying voltage-gated channel. An outwardly rectifying current-voltage relation is one where at any given driving force the outward flow of K+ ions exceeds the inward flow for the opposite driving force. [GOC:mah] |
GO:0071805 | potassium ion transmembrane transport | biological_process | A process in which a potassium ion is transported from one side of a membrane to the other. [GOC:mah] |
GO:0005228 | intracellular sodium-activated potassium channel activity | molecular_function | Enables the transmembrane transfer of potassium by a channel that opens in response to stimulus by a sodium ion or ions. Transport by a channel involves facilitated diffusion of a solute (by an energy-independent process) involving passage through a transmembrane aqueous pore or channel, without evidence for a carrier-mediated mechanism. Sodium activated potassium channels have distinctive properties, including a large single channel conductance, subconductance states, and a block of single channel currents at positive potentials, similar to inward rectification.
