Mechanistic Insight into Subunit Stoichiometry for KIR Channel Gating: Ligand Binding, Gating, Binding-Gating Coupling, Coordination, and Cooperativity [PDF]
, 2005 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 ...

Conformational changes in the catalytically inactive nucleotide-binding site of CFTR. [PDF]
, 2013 A central step in the gating of the cystic fibrosis transmembrane conductance regulator (CFTR) chloride channel is the association of its two cytosolic nucleotide-binding domains (NBDs) into a head-to-tail dimer, with two nucleotides bound at the ...

Gating Transition of Pentameric Ligand-Gated Ion Channels [PDF]
Biophysical Journal, 2009 Pentameric ligand-gated ion channels are an important family of membrane proteins and play key roles in physiological processes, including signal transduction at chemical synapses. Here, we study the conformational changes associated with the opening and closing of the channel pore.

The response of the tandem pore potassium channel TASK-3 (K2P9.1) to voltage : gating at the cytoplasmic mouth [PDF]
, 2009 Although the tandem pore potassium channel TASK-3 is thought to open and shut at its selectivity filter in response to changes of extracellular pH, it is currently unknown whether the channel also shows gating at its inner, cytoplasmic mouth through ...

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

Transcending Markov: non-Markovian rate processes of thermosensitive TRP ion channels
Royal Society Open Science, 2023 The Markov state model (MSM) is a popular theoretical tool for describing the hierarchy of time scales involved in the function of many proteins especially ion channel gating. An MSM is a particular case of the general non-Markovian model, where the rate

Palmitoylation of Voltage-Gated Ion Channels
International Journal of Molecular Sciences, 2022 Protein lipidation is one of the most common forms of posttranslational modification. This alteration couples different lipids, such as fatty acids, phospho- and glycolipids and sterols, to cellular proteins. Lipidation regulates different aspects of the protein’s physiology, including structure, stability and affinity for cellular membranes and ...
