How Does Our Knowledge on the Na+/H+ Exchanger NHE1 Obtained by Biochemical and Molecular Analyses Keep up With Its Recent Structure Determination?

open access: yesFrontiers in Physiology, 2022
Na+/H+ exchangers are membrane transporters conserved in all living systems and therefore are assumed to be amongst the most ancestral molecular devices that equipped the first protocells.

Dynamic change of electrostatic field in TMEM16F permeation pathway shifts its ion selectivity. [PDF]

open access: yes, 2019
TMEM16F is activated by elevated intracellular Ca2+, and functions as a small-conductance ion channel and as a phospholipid scramblase. In contrast to its paralogs, the TMEM16A/B calcium-activated chloride channels, mouse TMEM16F has been reported as a ...

Ion channels and ion selectivity [PDF]

open access: yesEssays in Biochemistry, 2017
Specific macromolecular transport systems, ion channels and pumps, provide the pathways to facilitate and control the passage of ions across the lipid membrane. Ion channels provide energetically favourable passage for ions to diffuse rapidly and passively according to their electrochemical potential.

Enzyme activity and selectivity filter stability of ancient TRPM2 channels were simultaneously lost in early vertebrates

open access: yeseLife, 2019
Transient Receptor Potential Melastatin 2 (TRPM2) is a cation channel important for the immune response, insulin secretion, and body temperature regulation. It is activated by cytosolic ADP ribose (ADPR) and contains a nudix-type motif 9 (NUDT9)-homology

The Citrus Flavonoid Hesperetin Has an Inadequate Anti-Arrhythmic Profile in the ΔKPQ NaV1.5 Mutant of the Long QT Type 3 Syndrome

open access: yesBiomolecules, 2020
Type 3 long QT syndromes (LQT3) are associated with arrhythmogenic gain-of-function mutations in the cardiac voltage-gated Na+ channel (hNaV1.5). The citrus flavanone hesperetin (HSP) was previously suggested as a template molecule to develop new anti ...

Estimating the true stability of the prehydrolytic outward-facing state in an ABC protein

open access: yeseLife, 2023
CFTR, the anion channel mutated in cystic fibrosis patients, is a model ABC protein whose ATP-driven conformational cycle is observable at single-molecule level in patch-clamp recordings.

Channel Optical Waveguides and Directional Couplers in GaAs -- Imbedded and Ridged [PDF]

open access: yes, 1973
Two-channel imbedded directional couplers were fabricated with proton implantation, yielding complete light transfer in 2 mm. Ridged channel guides were fabricated by ion-micromachining epitaxial layers, and a method of directional coupling was ...

Ion channel activity drives ion channel expression [PDF]

open access: yesThe Journal of Physiology, 1998
During embryonic development, excitable cells acquire a repertoire of ion channels that finely tune their electrical properties. Although the mechanisms by which an excitable cell selects its complement of ion channels are poorly defined, cell-autonomous as well as non-autonomous programmes of differentiation have been implicated.

Ion Channels of Nociception [PDF]

open access: yesInternational Journal of Molecular Sciences, 2020
The special issue “Ion Channels of Nociception” contains 13 articles published by 73 authors from different countries united by the main focusing on the peripheral mechanisms of pain. The content covers the mechanisms of neuropathic, inflammatory, and dental pain as well as pain in migraine and diabetes, nociceptive roles of P2X3, ASIC, Piezo and TRP ...

Obligate coupling of CFTR pore opening to tight nucleotide-binding domain dimerization

open access: yeseLife, 2016
In CFTR, the chloride channel mutated in cystic fibrosis (CF) patients, ATP-binding-induced dimerization of two cytosolic nucleotide binding domains (NBDs) opens the pore, and dimer disruption following ATP hydrolysis closes it.
