|Function||This potassium channel 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. This receptor plays a crucial role in regulating the heartbeat.|
|Cellular Location||Membrane; Multi-pass membrane protein.|

Potassium channels are present in most mammalian cells,where they participate in a wide range of physiologic responses.The protein encoded by this gene is an integral membrane proteinand inward-rectifier type potassium channel. The encoded protein,which has a greater tendency to allow potassium to flow into a cellrather than out of a cell, is controlled by G-proteins and plays animportant role in regulating heartbeat. It associates with threeother G-protein-activated potassium channels to form aheteromultimeric pore-forming complex.
