Contribution of Axon Initial Segment Structure and Channels to Brain Pathology

open access: yesCells, 2023
Brain channelopathies are a group of neurological disorders that result from genetic mutations affecting ion channels in the brain. Ion channels are specialized proteins that play a crucial role in the electrical activity of nerve cells by controlling ...

Executive Privilege in the Federal Courts [PDF]

open access: yes, 1962
Apoptosis is one type of programmed cell death, important during tissue development and to maintain the tissue homeostasis. Apoptosis comprises a complex network of internal signaling pathways, and an important part of this signaling network is the ...

Strategies for studying permeation at voltage-gated ion channels [PDF]

open access: yes, 1991
Voltage-dependent ion channels are presently thought to consist of several distinct functional regions: (a) activation gates, (b) inactivation gates, and permeation pathways.

Molecular dynamics of ion transport through the open conformation of a bacterial voltage-gated sodium channel [PDF]

open access: yes, 2013
The crystal structure of the open conformation of a bacterial voltage-gated sodium channel pore from Magnetococcus sp. (NaVMs) has provided the basis for a molecular dynamics study defining the channel’s full ion translocation pathway and conductance ...

Dual Regulation of Voltage-Sensitive Ion Channels by PIP2

open access: yesFrontiers in Pharmacology, 2012
Over the past 16 years, there has been an impressive number of ion channels shown to be sensitive to the major phosphoinositide in the plasma membrane, phosphatidilinositol 4,5-bisphosphate (PIP2). Among them are voltage-gated channels, which are crucial

Hysteretic Behavior in Voltage-Gated Channels

open access: yesFrontiers in Pharmacology, 2020
An ever-growing body of evidence has shown that voltage-gated ion channels are likely molecular systems that display hysteresis in their activity. This phenomenon manifests in the form of dynamic changes in both their voltage dependence of activity and ...

Lipid ion channels and the role of proteins [PDF]

open access: yes, 2013
Synthetic lipid membranes in the absence of proteins can display quantized conduction events for ions that are virtually indistinguishable from those of protein channel. By indistinguishable we mean that one cannot decide based on the current trace alone

Opposite effects of the S4-S5 linker and PIP2 on voltage-gated channel function: KCNQ1/KCNE1 and other channels

open access: yesFrontiers in Pharmacology, 2012
Voltage-gated potassium (Kv) channels are tetramers, each subunit presenting six transmembrane segments (S1-S6), with each S1-S4 segments forming a voltage-sensing domain (VSD) and the four S5-S6 forming both the conduction pathway and its gate.

Voltage gated inter-cation selective ion channels from graphene nanopores [PDF]

open access: yes, 2019
With the ability to selectively control ionic flux, biological protein ion channels perform a fundamental role in many physiological processes. For practical applications that require the functionality of a biological ion channel, graphene provides a ...
