Ligand recognition and gating mechanism through three ligand-binding sites of human TRPM2 channel
eLife, 2019 TRPM2 is critically involved in diverse physiological processes including core temperature sensing, apoptosis, and immune response. TRPM2’s activation by Ca2+ and ADP ribose (ADPR), an NAD+-metabolite produced under oxidative stress and neurodegenerative

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.

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 ...

Site-directed spin labeling reveals pentameric ligand-gated ion channel gating motions. [PDF]
PLoS Biology, 2013 Pentameric ligand-gated ion channels (pLGICs) are neurotransmitter-activated receptors that mediate fast synaptic transmission. In pLGICs, binding of agonist to the extracellular domain triggers a structural rearrangement that leads to the opening of an ...

The ligand gated ion channel database [PDF]
Nucleic Acids Research, 1999 The ligand gated ion channels (LGICs) are ionotropic receptors to neurotransmitters. Their physiological effect is carried out by the opening of an ionic channel upon binding of a particular neurotransmitter. These LGICs constitute superfamilies of receptors formed by homologous subunits.

Role of the Ion Channel Extracellular Collar in AMPA Receptor Gating
Scientific Reports, 2017 AMPA subtype ionotropic glutamate receptors mediate fast excitatory neurotransmission and are implicated in numerous neurological diseases. Ionic currents through AMPA receptor channels can be allosterically regulated via different sites on the receptor ...

Monod-Wyman-Changeux Analysis of Ligand-Gated Ion Channel Mutants [PDF]
, 2017 We present a framework for computing the gating properties of ligand-gated ion channel mutants using the Monod-Wyman-Changeux (MWC) model of allostery. We derive simple analytic formulas for key functional properties such as the leakiness, dynamic range,

A biomimetic chiral-driven ionic gate constructed by pillar[6]arene-based host–guest systems
Nature Communications, 2018 Uptake and release of glucose is regulated by glucose-sensitive ion channels, but complexity of the system impedes investigation of the gating behavior under physiological conditions.

Optical control of PIEZO1 channels
Nature Communications, 2023 PIEZO proteins are large, mechanically-activated trimeric ion channels. Here the authors report a light-gated mouse PIEZO1 channel, mOP1, whereby an azobenzene-based photoswitch covalently localised at the extracellular apex of a transmembrane helix ...
