Efficient Ion Sieving in Covalent Organic Framework Membranes with Sub‐2‐Nanometer Channels
Advances in Materials, 2021Membranes of sub‐2‐nanometer channels show high ion transport rates, but it remains a great challenge to design such membranes with desirable ion selectivities for ion separation applications.

Designing Biomimic Two-Dimensional Ionic Transport Channels for Efficient Ion Sieving.
ACS Nano, 2021Ion transport is crucial for biological systems and membrane-based technologies from both fundamental and practical aspects. Unlike biological ion channels, realizing efficient ion sieving by using membranes with artificial ion channels remains an ...

Science Signaling, 2001
The functions of ion channels can be regulated by their phosphorylation state. Protein kinases and protein phosphatases tightly control the activity of channels, thereby regulating the flow of ions across cell membranes. Channel proteins and kinases or phosphatases can associate directly or through intermediate adaptor proteins.

Ion channels are integral membrane proteins that contain pathways through which ions can flow. By shifting between closed and open conformational states ('gating' process), they control passive ion flow through the plasma membrane. Channels can be gated by membrane potential, or specific ligands, or other agents, such as mechanical stimuli.

Ubiquitylation of Ion Channels [PDF]
Physiology, 2005 Ubiquitylation (i.e., covalent attachment of ubiquitin moieties to proteins) of ion channels allows regulation of their activity and fate. Nedd4/Nedd4-like ubiquitin-protein ligases bind to, ubiquitylate, and modulate the internalization of several channels bearing PY motifs, whereas endoplasmic reticulum-associated degradation (involving ...

Abstract:In this section eight presenters focus on three distinct aspects of chromaffin cell biology: first, the properties of neuronal nicotinic receptors; second, the shaping of the Ca2+signals that underlie chromaffin cell function; and third, the properties and expression of cell surface transporter proteins.

Ion-Channel Reconstitution [PDF]
, 2007 In this chapter, a detailed protocol is given for ion-channel reconstitution in the two most used model membranes: planar bilayers and liposomes. In the planar bilayer section, methods are described for the expression of ion channels in Xenopus laevis oocytes, the isolation of their membranes, the insertion of ion channels into the bilayer by vesicle ...

Annual Review of Physiology, 1984
It may be reasonably argued that of all classes of known cellular proteins, the ion channels are the least understood biochemically. Of the large number of channel proteins known from cellular electrical behavior to exist in the mem branes of higher organisms, only three-the nicotinic acetylcholine receptor, the Na+ channel, and the mitochondrial ...
