ATP-sensitive potassium channelopathies: focus on insulin secretion

- nih.gov
FM Ashcroft - Journal of Clinical Investigation, 2005 - Am Soc Clin Investig
ATP-sensitive potassium (K ATP ) channels, so named because they are inhibited
by intracellular ATP , play key physiological roles in many tissues. In
pancreatic β cells, these channels regulate glucose-dependent insulin ...

KATP channels as molecular sensors of cellular metabolism


CG Nichols - Nature, 2006 - nature.com
Even in the absence of ATP, the single-channel kinetics of K ATP are complex,
but certain key features are clearly discernible and can be modelled by assuming
a single 'fast' gate and ligand-operated 'slow' gates within each subunit ...

Mutations in the genes encoding the pancreatic beta-cell KATP channel subunits Kir6. 2 ( …


AL Gloyn, J Siddiqui, S Ellard - Human mutation, 2006 - interscience.wiley.com
The beta-cell ATP-sensitive potassium channel is a key component of
stimulus-secretion coupling in the pancreatic beta-cell. The channel couples
metabolism to membrane electrical events, bringing about insulin secretion. ...

Insight in eukaryotic ABC transporter function by mutation analysis


A Frelet, M Klein - FEBS letters, 2006 - Elsevier
With regard to structure–function relations of ATP-binding cassette (ABC)
transporters several intriguing questions are in the spotlight of active
research: Why do functional ABC transporters possess two ATP binding and ...

Increased ATPase activity produced by mutations at arginine-1380 in nucleotide-binding …

- nih.gov
H de Wet, MG Rees, K Shimomura, J … - Proceedings of the National Academy of Sciences, 2007 - National Acad Sciences
Gain-of-function mutations in the genes encoding the ATP-sensitive potassium (K
ATP ) channel subunits Kir6.2 (KCNJ11) and SUR1 (ABCC8) are a common cause of
neonatal diabetes mellitus. Here we investigate the molecular mechanism by ...

Studies of the ATPase activity of the ABC protein SUR1


H de Wet, MV Mikhailov, C Fotinou, M Dreger, … - FEBS JOURNAL, 2007 - interscience.wiley.com
The ATP-sensitive potassium (K ATP ) channel couples glucose metabolism to
insulin secretion in pancreatic β-cells. It comprises regulatory sulfonylurea
receptor 1 and pore-forming Kir6.2 subunits. Binding and/or hydrolysis of ...
