Enables
This protein enables 4 target(s):
| Target | Category | Definition |
|---|---|---|
| inward rectifier potassium channel activity | molecular function | 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. [GOC:cb, GOC:mah, PMID:14977398] |
| ATP binding | molecular function | Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator. [ISBN:0198506732] |
| phosphatidylinositol-4,5-bisphosphate binding | molecular function | Binding to phosphatidylinositol-4,5-bisphosphate, a derivative of phosphatidylinositol in which the inositol ring is phosphorylated at the 4' and 5' positions. [GOC:bf, GOC:jl] |
| ATP-activated inward rectifier potassium channel activity | molecular function | 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 ATP. 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. [GOC:cb, GOC:mah] |
