An entropic mechanism of generating selective ion binding in macromolecules. [PDF]
PLoS Computational Biology, 2013 Several mechanisms have been proposed to explain how ion channels and transporters distinguish between similar ions, a process crucial for maintaining proper cell function.

Structural plasticity of the selectivity filter in a nonselective ion channel
IUCrJ, 2021 The sodium potassium ion channel (NaK) is a nonselective ion channel that conducts both sodium and potassium across the cellular membrane. A new crystallographic structure of NaK reveals conformational differences in the residues that make up the ...

Ion channels and ion selectivity [PDF]
Essays 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.

Ion Selectivity in the Selectivity Filters of Acid-Sensing Ion Channels [PDF]
Scientific Reports, 2015 Sodium-selective acid sensing ion channels (ASICs), which belong to the epithelial sodium channel (ENaC) superfamily, are key players in many physiological processes (e.g. nociception, mechanosensation, cognition, and memory) and are potential therapeutic targets.

Perspectives on: Ion selectivity [PDF]
Journal of General Physiology, 2011 The purpose of the Perspectives in General Physiology is to provide a forum where scientific uncertainties or controversies are discussed in an authoritative, yet open manner. The Perspectives are solicited by the editors—often based on recommendations by members of the editorial advisory board.

Ion-selective electrodes [PDF]
Postgraduate Medical Journal, 1999 Sir, In their review of hyponatraemia, Gill and Leese1 identify pseudohyponatraemia as a methodological problem which can lead to a spuriously low sodium. However, their assertion that this is not a problem when an ion-selective electrode (ISE) is used for sodium analysis needs clarification. Two types of methods using ISEs are currently in use within

Structural and thermodynamic properties of selective ion binding in a K+ channel.
PLoS Biology, 2007 Thermodynamic measurements of ion binding to the Streptomyces lividans K(+) channel were carried out using isothermal titration calorimetry, whereas atomic structures of ion-bound and ion-free conformations of the channel were characterized by x-ray ...

Potassium-selective channelrhodopsins
Biophysics and Physicobiology, 2023 Since their discovery 21 years ago, channelrhodopsins have come of age and have become indispensable tools for optogenetic control of excitable cells such as neurons and myocytes.
