The pharmacological properties of slow Ca(2+)-activated K(+) current (K(slow)) were investigated in mouse pancreatic beta-cells and islets to understand how K(slow) contributes to the control of islet bursting, [Ca(2+)](i) oscillations, and insulin secretion. K(slow) was insensitive to apamin or the K(ATP) channel inhibitor tolbutamide, but UCL 1684, a potent and selective nonpeptide SK channel...
