KCNJ9

Gene
KCNJ9
Protein
G protein-activated inward rectifier potassium channel 3
Organism
Homo sapiens
Length
393 amino acids
Function
This receptor is controlled by G proteins. 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 (By similarity).
Similarity
Belongs to the inward rectifier-type potassium channel (TC 1.A.2.1) family. KCNJ9 subfamily.
