KCNJ14

Gene
KCNJ14
Protein
ATP-sensitive inward rectifier potassium channel 14
Organism
Homo sapiens
Length
436 amino acids
Function
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. KCNJ14 gives rise to low-conductance channels with a low affinity to the channel blockers Barium and Cesium (By similarity).
Similarity
Belongs to the inward rectifier-type potassium channel (TC 1.A.2.1) family. KCNJ14 subfamily.
