The ABCs of ATP-sensitive Potassium Channels: More Pieces of the Puzzle

Curr Opin Cell Biol. 1997 Aug;9(4):553-9. doi: 10.1016/s0955-0674(97)80033-6.


ATP-sensitive potassium channels, KATP channels are critical for the normal regulation of insulin secretion. The cloning of cDNAs encoding the subunits of these channels shows that they are a novel combination of an ATP-binding protein and a small inward rectifier. Loss of pancreatic beta-cell KATP channels has been shown to cause familial hyperinsulinism.
