Gi2 proteins couple somatostatin receptors to low-conductance K+ channels in rat pancreatic alpha-cells.

Gi2 proteins couple somatostatin receptors to low-conductance K+ channels in rat pancreatic alpha-cells.

Somatostatin hyperpolarized rat pancreatic alpha-cells and inhibited spontaneous electrical activity by activating a low-conductance K+ channel (0.9 pS with physiological ionic gradients). This channel was insensitive to tolbutamide (a blocker of ATP-sensitive K+ channels) and apamin (an inhibitor o...
