Separate processes mediate nucleotide-induced inhibition and stimulation of the ATP-regulated K(+)-channels in mouse pancreatic beta-cells.
The mechanisms by which nucleotides stimulate the activity of the ATP-regulated K(+)-channel (KATP-channel) were investigated using inside-out patches from mouse pancreatic beta-cells. ATP produces a concentration-dependent inhibition of channel activity with a Ki of 18 microns. The inhibitory actio...
