CC -!- FUNCTION: This receptor is controled by G proteins. Inward
CC rectifier potassium channels are characterized by a greater
CC tendancy to allow potassium to flow into the cell rather than out
CC of it. Their voltage dependence is regulated by the concentration
CC of extracellular potassium; as external potassium is raised, the
CC voltage range of the channel opening shifts to more positive
CC voltages. The inward rectification is mainly due to the blockage
CC of outward current by internal magnesium. Can be blocked by
CC extracellular barium (By similarity).
CC -!- SUBUNIT: Associates with SUR (By similarity).
CC -!- SUBCELLULAR LOCATION: Integral membrane protein (By similarity).
CC -!- SIMILARITY: Belongs to the inward rectifier-type potassium channel
CC family.
