This protein enables 3 target(s):
| Target | Category | Definition |
|---|---|---|
| potassium channel activity | molecular function | Enables the 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. [GOC:BHF, GOC:mtg_transport, GOC:pr, ISBN:0815340729] |
| 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] |
| 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] |
This protein is located in 2 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] |
| synaptic vesicle | cellular component | A secretory organelle, typically 50 nm in diameter, of presynaptic nerve terminals; accumulates in high concentrations of neurotransmitters and secretes these into the synaptic cleft by fusion with the 'active zone' of the presynaptic plasma membrane. [PMID:10099709, PMID:12563290] |

This protein is involved in 3 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] |
| 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] |
