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.

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.

Cardiac Ion Channels [PDF]

open access: yesCirculation: Arrhythmia and Electrophysiology, 2009
The analysis of the molecular basis of the inherited cardiac arrhythmias has been the driving force behind the identification of the ion channels that generate the action potential. The genes encoding all the major ion channels have cloned and sequenced. The studies have revealed greater complexity than heretofore imagined.

The proposed channel-enzyme transient receptor potential melastatin 2 does not possess ADP ribose hydrolase activity

open access: yeseLife, 2016
Transient Receptor Potential Melastatin 2 (TRPM2) is a Ca2+-permeable cation channel essential for immunocyte activation, insulin secretion, and postischemic cell death.

Preventive treatment with ginsenoside Rb1 ameliorates monocrotaline-induced pulmonary arterial hypertension in rats and involves store-operated calcium entry inhibition

open access: yesPharmaceutical Biology, 2020
Context Ginsenoside Rb1, the main active ingredient of ginseng, exhibits ex vivo depression of store-operated calcium entry (SOCE) and related vasoconstriction in pulmonary arteries derived from pulmonary hypertension (PH) rats.

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.

Cardiac ion channels [PDF]

open access: yesChannels, 2015
Ion channels are critical for all aspects of cardiac function, including rhythmicity and contractility. Consequently, ion channels are key targets for therapeutics aimed at cardiac pathophysiologies such as atrial fibrillation or angina. At the same time, off-target interactions of drugs with cardiac ion channels can be the cause of unwanted side ...

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 ...
