Oxidative Modulation of Voltage-Gated Potassium Channels [PDF]
Antioxidants & Redox Signaling, 2014 Voltage-gated K+ channels are a large family of K+-selective ion channel protein complexes that open on membrane depolarization. These K+ channels are expressed in diverse tissues and their function is vital for numerous physiological processes, in particular of neurons and muscle cells.

Lipid ion channels and the role of proteins [PDF]
, 2013 Synthetic lipid membranes in the absence of proteins can display quantized conduction events for ions that are virtually indistinguishable from those of protein channel. By indistinguishable we mean that one cannot decide based on the current trace alone

Ion channel gating: a first passage time analysis of the Kramers type [PDF]
, 2001 The opening rate of voltage-gated potassium ion channels exhibits a characteristic, knee-like turnover where the common exponential voltage-dependence changes suddenly into a linear one.

Photochromic Blockers of Voltage‐Gated Potassium Channels [PDF]
Angewandte Chemie International Edition, 2009 Photochromic ligands (PCLs) can be optically switchedbetween isomers that show different biological activities. Assuch, they offer an opportunity to convert ligand-actuatedpathways into light-actuated pathways, thus making it possi-ble to control a wide range of biological processes with light.PCLs have been explored for various classes of ...

Voltage-dependent gating of KCNH potassium channels lacking a covalent link between voltage-sensing and pore domains [PDF]
, 2015 Voltage-gated channels open paths for ion permeation upon changes in membrane potential, but how voltage changes are coupled to gating is not entirely understood.

Outward Rectification of Voltage-Gated K+ Channels Evolved at Least Twice in Life History. [PDF]
PLoS ONE, 2015 Voltage-gated potassium (K+) channels are present in all living systems. Despite high structural similarities in the transmembrane domains (TMD), this K+ channel type segregates into at least two main functional categories-hyperpolarization-activated ...
