Polyunsaturated fatty acids modify the gating of Kv channels
Frontiers in Pharmacology, 2012 Polyunsaturated fatty acids (PUFAs) have been reported to exhibit antiarrhythmic properties, which are attributed to their capability to modulate ion channels.

Distinct gating mechanisms revealed by the structures of a multi-ligand gated K+ channel
eLife, 2012 The gating ring-forming RCK domain regulates channel gating in response to various cellular chemical stimuli in eukaryotic Slo channel families and the majority of ligand-gated prokaryotic K+ channels and transporters.

The selectivity, voltage-dependence and acid sensitivity of the tandem pore potassium channel TASK-1 : contributions of the pore domains [PDF]
, 2007 We have investigated the contribution to ionic selectivity of residues in the selectivity filter and pore helices of the P1 and P2 domains in the acid sensitive potassium channel TASK-1.

Structure, dynamics and implied gating mechanism of a human cyclic nucleotide-gated channel.
PLoS Computational Biology, 2014 Cyclic nucleotide-gated (CNG) ion channels are nonselective cation channels, essential for visual and olfactory sensory transduction. Although the channels include voltage-sensor domains (VSDs), their conductance is thought to be independent of the ...

Glutamate-gated Chloride Channels [PDF]
Journal of Biological Chemistry, 2012 Glutamate-gated chloride channels (GluCls) are found only in protostome invertebrate phyla but are closely related to mammalian glycine receptors. They have a number of roles in these animals, controlling locomotion and feeding and mediating sensory inputs into behavior.

Effects of ionic strength on gating and permeation of TREK-2 K2P channels.
PLoS ONE, 2021 In addition to the classical voltage-dependent behavior mediated by the voltage-sensing-domains (VSD) of ion channels, a growing number of voltage-dependent gating behaviors are being described in channels that lack canonical VSDs.

Voltage-Gated Calcium Channels [PDF]
Cold Spring Harbor Perspectives in Biology, 2010 Voltage-gated calcium (Ca(2+)) channels are key transducers of membrane potential changes into intracellular Ca(2+) transients that initiate many physiological events. There are ten members of the voltage-gated Ca(2+) channel family in mammals, and they serve distinct roles in cellular signal transduction.

Cytoplasmic domains and voltage-dependent potassium channel gating
Frontiers in Pharmacology, 2012 The basic architecture of the voltage-dependent K+ channels (Kv channels) corresponds to a transmembrane protein core in which the permeation pore, the voltage sensing components and the gating machinery (cytoplasmic facing gate and sensor-gate coupler ...

Voltage-gated proton channels [PDF]
Cellular and Molecular Life Sciences, 2008 Voltage-gated proton channels, HV1, have vaulted from the realm of the esoteric into the forefront of a central question facing ion channel biophysicists, namely, the mechanism by which voltage-dependent gating occurs. This transformation is the result of several factors.

Ion channels gated by heat [PDF]
Proceedings of the National Academy of Sciences, 1999 All animals need to sense temperature to avoid hostile environments and to regulate their internal homeostasis. A particularly obvious example is that animals need to avoid damagingly hot stimuli. The mechanisms by which temperature is sensed have until recently been mysterious, but in the last couple of years, we have begun to understand how ...
