ATP-sensitive inward rectifier potassium channel 15

Gene

Kcnj15

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: -Experimental evidence at transcript leveli

Functioni

Inward rectifier potassium channels are characterized by a greater tendency to allow potassium to flow into the cell rather than out of it. Their voltage dependence is regulated by the concentration of extracellular potassium; as external potassium is raised, the voltage range of the channel opening shifts to more positive voltages. The inward rectification is mainly due to the blockage of outward current by internal magnesium.
