Enables
This protein enables 3 target(s):
| Target | Category | Definition |
|---|
| calcium-activated potassium channel activity | molecular function | Enables the calcium concentration-regulatable energy-independent passage of potassium ions across a lipid bilayer down a concentration gradient. [GOC:dph, GOC:mtg_transport] |
| 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] |
| potassium ion leak channel activity | molecular function | Enables the transport of a potassium ion across a membrane via a narrow pore channel that is open even in an unstimulated or 'resting' state. [GOC:mtg_transport, ISBN:0815340729] |
Located In
This protein is located in 1 target(s):
| Target | Category | Definition |
|---|
| 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] |
Active In

| Target | Category | Definition |
|---|
| 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] |
Involved In
This protein is involved in 5 target(s):
| Target | Category | Definition |
|---|
| potassium ion transport | biological process | 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. [GOC:ai] |
| cellular response to pH | biological process | Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a pH stimulus. pH is a measure of the acidity or basicity of an aqueous solution. [GOC:mah, Wikipedia:PH] |
| 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] |
| stabilization of membrane potential | biological process | The accomplishment of a non-fluctuating membrane potential, the electric potential existing across any membrane arising from charges in the membrane itself and from the charges present in the media on either side of the membrane. [GOC:jl, ISBN:0198506732] |
| 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] |
