Functional analysis of six Kir6.2 (KCNJ11) mutations causing neonatal diabetes.

Functional analysis of six Kir6.2 (KCNJ11) mutations causing neonatal diabetes.

ATP-sensitive potassium (K(ATP)) channels, composed of pore-forming Kir6.2 and regulatory sulphonylurea receptor (SUR) subunits, play an essential role in insulin secretion from pancreatic beta cells. Binding of ATP to Kir6.2 inhibits, whereas interaction of Mg-nucleotides with SUR, activates the ch...
