An Anion Selective Aminocyclodextrin Ion Channel: Ion Selectivity, pH Sensitivity and Potential as a Scaffold for Light Gating
… also indicated that the ion channel was highly anion selective with anion transport rates being ClO4- > I- > NO3- > Br- > Cl-. The rates for the transport of ClO4 -, I-, NO3- and Br- ions were ca. 20, 9, 3.1 and 2.6 times that for Na + ions, respectively. The anion selectivity for the ion …

Molecular determinants of conductance and charge-selectivity in pentameric ligand-gated ion channels
… mechanism of conductance through the cation-selective nicotinic AChR from muscle is studied. In the second part, the molecular determinants of charge-selectivity in anion-selective pLGICs is studied. In cation-selective members of the superfamily, rings of glutamates (and, more rarely, …

Sensing with Nanomaterials: Controlling Transport, Single Molecule Detection, and Voltage Sensing
… throughout is introduced, demonstrating cation selective behaviour using graphene and hBN through such capillaries. The cause of such selectivity is explored within the context of cation selectivity. Developing on from this, control over membrane surface charge is expressed allowing for anion …

Channel-forming proteins in the cell wall of amino acid-producing Corynebacteria
… column. The purified protein forms cation-selective channels with a diameter of about 2.2 nm and an average single-channel conductance of about 2.5 nS in 1 M KCl in the lipid bilayer assay. Organic solvent extracts were used to study the permeability properties of the cell wall of C. …

Mechanisms of ion channel activation in primary cultured and clonal cell lines
… a monoexponential time course. The currents were anion selective and exhibited a selectivity sequence of SCN- > I > Br- > Cl- > F- > gluconate. Current activation was unaffected by inhibitors of protein kinase (A (H-89) and tyrosine kinase (tyrphostin A25), and could not be mimicked by elevation …

Patterning the Mud Snail Ilyanassa obsoleta: The Role of Cell Signaling and Asymmetric Protein Localization
… lobe isolates. I identified voltage-dependent anion-selective channel (VDAC) as one of the candidate proteins enriched in polar lobe isolates. I propose that VDAC is asymmetrically distributed by the polar lobe to the D cell and that it may function in D cell induction and mesendoderm fate …

Regolazione trascrizionale delle isoforme VDAC umane: analisi dei loro profili di espressione, dell'attività del promotore e dei regolatori trascrizionali
I VDAC (Voltage Dependent Anion-selective Channels) sono proteine canale localizzate nella membrana mitocondriale esterna dove mediano principalmente gli scambi metabolici tra citosol e mitocondri. Negli eucarioti superiori, i VDAC formano una famiglia multigenica che include tre isoforme (VDAC1-3) …

Main Group Hydrogen-Bond Donors and Pyridyl Ligands for Supramolecular and Coordination Chemistry
… chapter we develop strategies for enhancing the anion binding properties of phosphazanes of the type [(RNH)(E)P(µ-NtBu)]2 (E = O, S, Se) which are bench stable, H-bond receptors that can be regarded as inorganic analogues of squaramides (a key class of organic anion receptor). We find that there …

Differential proteome analysis of human lung epithelial cells following exposure to aromatic volatile organic compounds
… all three volatile compounds: voltage-dependent anion-selective channel protein 2, peroxiredoxin 1 and elongation factor 2. However, all of these proteins are important molecular targets in stress- and cell death-related signaling pathways.

The CFTR (Cystic Fibrosis Transmembrane Conductance Regulator) Channel: Anion Permeation, and Regulation by Adenylyl Cyclase and ATP Hydrolysis
… inhibitor of Iso's stimulatory action. Anion selectivity of CFTR channels was determined by shifts of the reversal potential (E<sub>rev</sub>) for CFTR channel current on changes in extracellular [Cl<sup>-</sup>] ([Cl<sup>-</sup>]<sub>0</sub>): E<sub>rev</sub> shifted roughly linearly …
