Gating and selectivity mechanisms for the lysosomal K+ channel TMEM175
eLife, 2020 Transmembrane protein 175 (TMEM175) is a K+-selective ion channel expressed in lysosomal membranes, where it establishes a membrane potential essential for lysosomal function and its dysregulation is associated with the development of Parkinson’s Disease.

Un-gating and allosteric modulation of a pentameric ligand-gated ion channel captured by molecular dynamics. [PDF]
PLoS Computational Biology, 2017 Pentameric ligand-gated ion channels (pLGICs) mediate intercellular communication at synapses through the opening of an ion pore in response to the binding of a neurotransmitter. Despite the increasing availability of high-resolution structures of pLGICs,

Investigation of K2P channel permeation and gating [PDF]
, 2020 The ability to conduct potassium ions (K+) selectively in the abundant presence of other ion species is crucial to the function of K+ channels. While the mechanism of ion selectivity has been an in- tensely studied and debated topic, the protein ...

Advanced Functional Materials, EarlyView.Monolithic UV‐ozone oxidation of Ta forms an ultrathin Ta2O5/TaOx bilayer enabling resistive switching with a vertical defect gradient. A stoichiometric surface layer over an oxygen‐deficient sublayer promotes localized filament nucleation near the top interface, enabling low‐voltage operation, and reduced cycle‐to‐cycle variability.
