A new polymodal gating model of the proton-activated chloride channel.
The proton-activated chloride (PAC) channel plays critical roles in ischemic neuron death, but its activation mechanisms remain elusive. Here, we investigated the gating of PAC channels using its novel bifunctional modulator C77304.

Bubbles, Gating, and Anesthetics in Ion Channels [PDF]
We suggest that bubbles are the bistable hydrophobic gates responsible for the on-off transitions of single channel currents. In this view, many types of channels gate by the same physical mechanism-dewetting by capillary evaporation-but different types of channels use different sensors to modulate hydrophobic properties of the channel wall and thereby

Understanding the gating mechanism of ion channel proteins is key to understanding the regulation of cell signaling through these channels. Channel opening and closing are regulated by diverse environmental factors that include temperature, electrical ...

Molecular mechanisms of the coupling of gating to voltage sensing in transmembrane proteins [PDF]
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.

Effects of ionic strength on gating and permeation of TREK-2 K2P channels.
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.

Flexibility of the N-Terminal mVDAC1 Segment Controls the Channel’s Gating Behavior [PDF]
Since the solution of the molecular structures of members of the voltage dependent anion channels (VDACs), the N-terminal α-helix has been the main focus of attention, since its strategic location, in combination with its putative conformational ...

Mechanistic Insight into Subunit Stoichiometry for KIR Channel Gating: Ligand Binding, Gating, Binding-Gating Coupling, Coordination, and Cooperativity [PDF]
Ligand-gated ion channels couple intra- and extracellular chemical signals to cellular excitability. In response to a specific ligand, these channels change their permeability to certain ions by opening or closing their ion conductive pathway, a ...

Studies of NMDA receptor function and stoichiometry with truncated and tandem subunits [PDF]
The subunits that compose eukaryotic glutamate ion channel receptors have three transmembrane domains (TMs) and terminate with intracellular tails that are important for controlling channel expression and localization.
