Alternative Targets for Modulators of Mitochondrial Potassium Channels

open access: yesMolecules, 2022
Mitochondrial potassium channels control potassium influx into the mitochondrial matrix and thus regulate mitochondrial membrane potential, volume, respiration, and synthesis of reactive oxygen species (ROS).

Drunk potassium channels [PDF]

open access: yesEuropace, 2011
We report the case of a 42-year-old woman who was admitted due to alcohol induced dehydration leading to cardiac symptoms. On physical examination severe hypokalaemia and long QT syndrome were apparent. During potassium (K+) supplementation we simultaneously observed QT interval recovery.

Hydrogen Sulfide-Induced Vasodilation: The Involvement of Vascular Potassium Channels

open access: yesFrontiers in Pharmacology, 2022
Hydrogen sulfide (H2S) has been highlighted as an important gasotransmitter in mammals. A growing number of studies have indicated that H2S plays a key role in the pathophysiology of vascular diseases and physiological vascular homeostasis. Alteration in

Potassium channels [PDF]

open access: yesFEBS Letters, 2003
The atomic structures of K+ channels have added a new dimension to our understanding of K+ channel function. I will briefly review how structures have influenced our views on ion conduction, gating of the pore, and voltage sensing.

Potassium channel regulation [PDF]

open access: yesEMBO reports, 2003
The sulphonylurea receptor (SUR) is a member of the ATP-binding cassette (ABC) family of membrane proteins. It functions as the regulatory subunit of the ATP-sensitive potassium (KATP) channel, which comprises SUR and Kir6.x proteins. Here, we review data demonstrating functional differences between the two nucleotide binding domains (NBDs) of SUR1. In

ATP-Sensitive Potassium Channels and Their Physiological and Pathophysiological Roles.

open access: yesComprehensive Physiology, 2018
ATP sensitive potassium channels (KATP ) are so named because they open as cellular ATP levels fall. This leads to membrane hyperpolarization and thus links cellular metabolism to membrane excitability.

Potassium Ion Channels in Glioma: From Basic Knowledge into Therapeutic Applications

open access: yesMembranes, 2023
Ion channels, specifically those controlling the flux of potassium across cell membranes, have recently been shown to exhibit an important role in the pathophysiology of glioma, the most common primary central nervous system tumor with a poor prognosis ...

Potassium Channel Mechanics [PDF]

open access: yesNeuron, 2001
What is the moving part that switches an ion channel's current on and off? In this issue of Neuron del Camino and Yellen (2001) exploit scanning cysteine mutagenesis and sulfhydryl reagents to show that the intracellular end of the S6 helices forms a mechanical gate for the Shaker potassium channel.
