Abstract excerpt
ATP-sensitive potassium (K(ATP)) channels of pancreatic beta-cells mediate glucose-induced insulin secretion by linking glucose metabolism to membrane excitability. The number of plasma membrane K(ATP) channels determines the sensitivity of beta-cells to glucose stimulation. The K(ATP) channel is formed in the endoplasmic reticulum (ER) on coassembly of four inwardly rectifying potassium channel Kir6.2 subunits...
