Critical Role of Gap Junction Coupled K(ATP)Channel Activity for Regulated Insulin Secretion.
Pancreatic beta-cells secrete insulin in response to closure of ATP-sensitive K(+) (K(ATP)) channels, which causes membrane depolarization and a concomitant rise in intracellular Ca(2+) (Ca(i)). In intact islets, beta-cells are coupled by gap junctions, which are proposed to synchronize electrical a...
