Molecular mechanisms of the coupling of gating to voltage sensing in transmembrane proteins [PDF]
, 2014 Voltage gated potassium ion (Kv) channels regulate action potentials of the nervous system by responding to changes in transmembrane voltage, enabling K+ transport across the membrane to restore cells to their resting potential.

Patch clamp studies of human sperm under physiological ionic conditions reveal three functionally and pharmacologically distinct cation channels [PDF]
, 2014 Whilst fertilizing capacity depends upon a K+ conductance G? that allows the spermatozoon membrane potential Vm to be held at a negative value, the characteristics of this conductance in human sperm are virtually unknown.

Membrane trafficking of ATP-sensitive potassium channels [PDF]
, 2005 ATP-sensitive potassium (KATp) channels are known to play a vital role in the regulation of insulin secretion from pancreatic 0-cells. Changes in the ratio of [ATP]/[ADP] within the cell are known to regulate the activity of channels, but very little is ...

Effects of cromakalim (BRL 34915) on potassium conductances in CA3 neurons of the guinea-pig hippocampus in vitro [PDF]
, 1989 The action of the potassium channel activator, cromakalim (BRL 34915), on membrane potential, input resistance and current-voltage-relationship of CA3 neurons in a slice preparation of the guinea-pig hippocampus was investigated by means of intracellular

Self-organized enhancement of conductivity in biological ion channels [PDF]
, 2013 We discuss an example of self-organization in a biological system. It arises from long-range ion–ion interactions, and it leads us to propose a new kind of enhanced conduction in ion channels.

Do KATP channels open as a prominent and early feature during ischaemia in the Langendorff-perfused rat heart? [PDF]
, 2000 The objective was to investigate whether myocardial adenosine triphosphate-sensitive K<sup>+</sup> (K<sub>ATP</sub>) channels open during the first 10 min of regional ischaemia in Langendorff-perfused rat hearts.

Structural and functional studies of K2P channels
, 2015 Two-pore domain potassium channels (K2Ps) are a family of dimeric potassium channels responsible for regulation of cellular excitability. In 2012, crystal structures of TREK-2 were solved revealing this channel in two different conformational states. In

Extracellular blockade of K(+) channels by TEA : results from molecular dynamics simulations of the KcsA channel [PDF]
, 2001 TEA is a classical blocker of K(+) channels. From mutagenesis studies, it has been shown that external blockade by TEA is strongly dependent upon the presence of aromatic residue at Shaker position 449 which is located near the extracellular entrance to ...
