TL;DR
It is hypothesize that slide helix position in the membrane might possibly act as a "conformational switch" in regulating the KirBac1.1 function, and results involving dynamic lipid-protein interactions in lipid-dependent gating might be relevant for other Kir channels.
This work identified the key molecular determinant in the hHv1 channel that mediates cholesterol inhibition and also provided a mechanism linking the conversion between demosterol and cholesterol by DHCR24 to pH homeostasis in many cells, such as phagocytes, cardiomyocytes, neurons and microglial cells.
This paper reports on a plausible mechanism of modulation by anionic phospholipids of KcsA, a model prokaryotic potassium channel. A first conclusion is that the association of anionic phospholipids with KcsA occurs at discrete regions located near both the extracellular and intracellular channel gates. This same behav...
The binding sites of the channel for various ligands/modulators are highlighted, and an emerging model focusing on the structural rearrangements associated with the transition of the channel from the closed/deactivated to open/activated conformation during lipid-dependent gating is provided which should be broadly appl...
The findings establish the periplasmic loop as a structural domain fine-tuning MscL gating through electrostatic interactions with surrounding lipids through electrostatic interactions with surrounding lipids.
This article shows that this plasticity is governed by a distal allosteric network that allows TPC2 to discriminate between agonists and generate specific lysosomal ion fluxes, and Mutant channels exhibit enhanced Ca²⁺ permeability and adopt a co-activated-like state.
A proposed mechanism in which helix 8 functions as a surface-active amphipathic element that promotes membrane binding, senses membrane curvature, and thereby facilitates GPCR trafficking is examined, supporting a broader model in which surface-active amphipathic motifs tune membrane protein trafficking by coupling dyn...
