Residue 39 of Kir6.2 drives a difference in ATP sensitivity in human and canine beta-cell K<sub>ATP</sub> channels. [PDF]
ATP-sensitive potassium (KATP) channels link beta-cell metabolism to electrical activity. By modulating the beta-cell membrane potential, they finely regulate glucose-stimulated insulin secretion.

Cardiac ventricular Kir6.1 ATP-sensitive potassium channels: an overlooked effector of cardioprotection. [PDF]
IntroductionAdenosine triphosphate (ATP)-sensitive potassium (KATP) channels are octameric structures, comprising a pore-forming homotetramer of Kir6.1 or Kir6.2, with 4 accessory sulphonylurea receptor (SUR) subunits.

The Structural Basis for the Binding of Repaglinide to the Pancreatic KATP Channel
Summary: Repaglinide (RPG) is a short-acting insulin secretagogue widely prescribed for the treatment of type 2 diabetes. It boosts insulin secretion by inhibiting the pancreatic ATP-sensitive potassium channel (KATP).
