Similarity of the ion occupations of K+ and Tl+ in the selectivity filter of a K+ channel, as verified by single-channel currents

Channels
Voltage-dependent gating in the selectivity filter of potassium channels is modulated by the permeating ions binding within the filter. In the viral Kcv channel, filter gating occurs on the sub-millisecond time scale.

The Hydrophobic Effect Contributes to the Closed State of a Simplified Ion Channel through a Conserved Hydrophobic Patch at the Pore-Helix Crossing.

Frontiers in Pharmacology, 2015
Ion selectivity-filter structures are strikingly similar throughout the large family of K+ channels and other p-loop-like receptors (i.e., glutamate receptors). At the same time, the triggers for opening these channels, or gating, are diverse.

FKBP12 activates the cardiac ryanodine receptor Ca2+-release channel and is antagonised by FKBP12.6 [PDF]

, 2012
Changes in FKBP12.6 binding to cardiac ryanodine receptors (RyR2) are implicated in mediating disturbances in Ca2+-homeostasis in heart failure but there is controversy over the functional effects of FKBP12.6 on RyR2 channel gating.

Structure‐Guided Balancing of Ambipolar Transport Enables Symmetric Switching in Heterojunction Bilayer Organic Transistor Inverters

Advanced Functional Materials, EarlyView.
Balancing the spatially separated p‐ and n‐type transport pathways in heterojunction‐bilayer OTFTs enables symmetric inverter switching (VM ≈ 0.5VDD), whereas discrete integration of unipolar OTFTs gives polarity‐dependent and resistive responses. ABSTRACT High inverter performance in ambipolar organic electronics requires balanced channel strengths ...

An Adaptive Inhibitory WSe2 Transistor for Retinomorphic In‐Sensor Image Processing

Advanced Functional Materials, EarlyView.
Conventional retinomorphic devices typically require deliberate gate‐bias tuning for each illumination condition. In this paper, we demonstrate an adaptive inhibitory WSe2 transistor that uses photo‐induced regime shift between the subthreshold and accumulation modes to achieve decision‐free, intensity‐adaptive image processing within a single pixel ...

Kinetic model based on molecular mechanism for action potential [PDF]

, 2011
The Hodgkin-Huxley model for action potentials has been widely used but was not built on a microscopic description of the neuronal membrane. Through molecular dynamics simulations, the molecular mechanism of the channel currents is becoming clear ...

Genetically Programmed Shape‐Morphing of Engineered Living Materials

Advanced Functional Materials, EarlyView.
Here, bacterial and mammalian engineered living materials (ELMs) are presented, in which living cells direct genetically programmed and enzymatically mediated shape‐morphing. The resulting deformation and shape‐recovery can be actuated in a genetically controlled manner by an ELM incorporating out‐of‐equilibrium counteracting biochemical reactions with
