Hydrophobic Gating in Ion Channels
Journal of Molecular Biology, 2015 Biological ion channels are nanoscale transmembrane pores. When water and ions are enclosed within the narrow confines of a sub-nanometer hydrophobic pore, they exhibit behavior not evident from macroscopic descriptions. At this nanoscopic level, the unfavorable interaction between the lining of a hydrophobic pore and water may lead to stochastic ...

Optical control of an ion channel gate [PDF]
Proceedings of the National Academy of Sciences, 2013 Significance Engineered light-sensitive ion channels offer the opportunity to govern electrical activity of neurons. To date, developed strategies have relied on specific actions on either ligand-binding or permeation pathways. Here we developed a unique and versatile method, in which the gating machinery of an ATP-activated channel ...

Sodium channel inactivation kinetics of rat sensory and motor nerve fibres and their modulation by glutathione [PDF]
, 1993 Na+ channel currents of rat motor and sensory nerve fibres were studied with the patch-clamp technique on enzymatically demyelinated axons. Differences between motor and sensory fibres in multi-channel inactivation kinetics and the gating of late single ...

A nomenclature for ligand-gated ion channels [PDF]
Neuropharmacology, 2009 The ligand-gated ion channels that participate in fast synaptic transmission comprise the nicotinic acetylcholine, 5-hydroxytryptamine3 (5-HT3), gamma-aminobutyric acidA (GABA(A)), glycine, ionotropic glutamate and P2X receptor families. A consistent and systematic nomenclature for the individual subunits that comprise these receptors and the receptors

PLoS Computational Biology, 2010 Neuronal activity is mediated through changes in the probability of stochastic transitions between open and closed states of ion channels. While differences in morphology define neuronal cell types and may underlie neurological disorders, very little is ...

An Unorthodox Mechanism Underlying Voltage Sensitivity of TRPV1 Ion Channel
Advanced Science, 2020 While the capsaicin receptor transient receptor potential vanilloid 1 (TRPV1) channel is a polymodal nociceptor for heat, capsaicin, and protons, the channel's responses to each of these stimuli are profoundly regulated by membrane potential, damping or ...

Studies of NMDA receptor function and stoichiometry with truncated and tandem subunits [PDF]
, 2003 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.

Molecular simulations of ion channel gating [PDF]
, 2022 Ion channels are membrane proteins that facilitate ion permeation across the membrane down the concentration gradient. Recently, many structures of the ion channels were solved using cryo-electron microscopy.

Implications of stochastic ion channel gating and dendritic spine plasticity for neural information processing and storage [PDF]
, 2012 On short timescales, the brain represents, transmits, and processes information through the electrical activity of its neurons. On long timescales, the brain stores information in the strength of the synaptic connections between its neurons.

Piezo’s membrane footprint and its contribution to mechanosensitivity
eLife, 2018 Piezo1 is an ion channel that gates open when mechanical force is applied to a cell membrane, thus allowing cells to detect and respond to mechanical stimulation.
