C Maffeo, S Bhattacharya, J Yoo, D Wells… - Chemical …, 2012 - ACS Publications
Transport of ions through pores in membranes is a process of fundamental importance to
cell biology. In living organisms, such transport is facilitated by ion channels that utilize the …

Molecular basis of force-from-lipids gating in the mechanosensitive channel MscS

B Reddy, N Bavi, A Lu, Y Park, E Perozo - Elife, 2019 - elifesciences.org
Prokaryotic mechanosensitive (MS) channels open by sensing the physical state of the
membrane. As such, lipid-protein interactions represent the defining molecular process …

Nanofluidics at the crossroads

P Robin, L Bocquet - The Journal of Chemical Physics, 2023 - pubs.aip.org
Nanofluidics, the field interested in flows at the smallest scales, has grown at a fast pace,
reaching an ever finer control of fluidic and ionic transport at the molecular level. Until now …

Molecular force transduction by ion channels–diversity and unifying principles

S Sukharev, F Sachs - Journal of cell science, 2012 - journals.biologists.com
Cells perceive force through a variety of molecular sensors, of which the mechanosensitive
ion channels are the most efficient and act the fastest. These channels apparently evolved to …

A hydrophobic barrier deep within the inner pore of the TWIK-1 K2P potassium channel
