Electric fingerprint of voltage sensor domains [PDF]

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2014
Significance A central paradigm in the subject of cellular excitability is whether or not a dynamic membrane voltage field contributes to the operation of voltage sensor proteins. This issue has challenged an entire generation of scientists because static and dynamic contributions of the field cannot be discriminated from electrophysiology ...

Similar voltage-sensor movement in spHCN channels can cause closing, opening, or inactivation. [PDF]

open access: yesJ Gen Physiol, 2023
Hyperpolarization-activated cyclic nucleotide-gated (HCN) channels contribute to the rhythmic firing of pacemaker neurons and cardiomyocytes. Mutations in HCN channels are associated with cardiac arrhythmia and epilepsy.

A Voltage-Sensor Water Pore [PDF]

open access: yesBiophysical Journal, 2006
Voltage-sensor (VS) domains cause the pore of voltage-gated ion channels to open and close in response to changes in transmembrane potential. Recent experimental studies suggest that VS domains are independent structural units. This independence is revealed dramatically by a voltage-dependent proton-selective channel (Hv), which has a sequence ...

Voltage Sensor Movements [PDF]

open access: yesThe Journal of General Physiology, 2002
The voltage dependence of K+, Na+, and Ca2+ channels is brought about by a voltage sensor that moves ∼12–13 e across the entire electric field ([Schoppa et al., 1992][1]; [Hirschberg et al., 1996][2]; [Noceti et al., 1996][3]).

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

open access: yes, 2014
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.

Uncooperative Voltage Sensors [PDF]

open access: yesJournal of General Physiology, 2009
A typical voltage-gated potassium (Kv) or sodium channel is exquisitely sensitive to small changes of membrane potential, so much so that a depolarization of

Voltage Sensor Inactivation in Potassium Channels [PDF]

open access: yesFrontiers in Pharmacology, 2012
In voltage-gated potassium (Kv) channels membrane depolarization causes movement of a voltage sensor domain. This conformational change of the protein is transmitted to the pore domain and eventually leads to pore opening. However, the voltage sensor domain may interact with two distinct gates in the pore domain: the activation gate (A-gate), involving

Epidermal Passive RFID Strain Sensor for Assisted Technologies [PDF]

open access: yes, 2014
An epidermal passive wireless strain sensor using RFID tags is presented. The tag is intended to detect eyebrow or neck skin stretch where paraplegic patients have the capability to tweak facial muscles.

Optimization of soot deposition by high-temperature prepolarization of a resistive particulate matter sensor [PDF]

open access: yes, 2020
For the purposes of the onboard diagnosis (OBD) of diesel particulate filters (DPFs) in diesel exhaust treatment systems, a particulate matter (PM) sensor is applied downstream from the DPFs to detect small amounts of diesel soot that passed through the ...
