Functional Coupling of Cav2.3 and BK Potassium Channels Regulates Action Potential Repolarization and Short-Term Plasticity in the Mouse Hippocampus

Frontiers in Cellular Neuroscience, 2019
Voltage-gated ion channels are essential for signal generation and propagation in neurons and other excitable cells. The high-voltage activated calcium-channel Cav2.3 is expressed throughout the central and peripheral nervous system, and within CA1 ...

Outward Rectification of Voltage-Gated K+ Channels Evolved at Least Twice in Life History. [PDF]

PLoS ONE, 2015
Voltage-gated potassium (K+) channels are present in all living systems. Despite high structural similarities in the transmembrane domains (TMD), this K+ channel type segregates into at least two main functional categories-hyperpolarization-activated ...

A nongenomic mechanism for progesterone-mediated immunosuppression: Inhibition of K+ channels, Ca2+ signaling, and gene expression in T lymphocytes [PDF]

, 1998
The mechanism by which progesterone causes localized suppression of the immune response during pregnancy has remained elusive. Using human T lymphocytes and T cell lines, we show that progesterone, at concentrations found in the placenta, rapidly and ...

Role of potassium conductance in mechanisms of exrtacellular atp impact on the contractive activity of vascular smooth muscle cells

Бюллетень сибирской медицины, 2017
The purpose of this work is to study the influence of extracellular ATP (adenosine-3-phosphate), which is an activator of purinergic receptors, on contractive activity of rat aortic ring segments precontracted by α1-adrenoreceptors activation with ...

Computational identification of residues that modulate voltage sensitivity of voltage-gated potassium channels [PDF]

, 2005
Background: Studies of the structure-function relationship in proteins for which no 3D structure is available are often based on inspection of multiple sequence alignments.

Light-Induced Control of Voltage Gated Ion Channels [PDF]

, 2022
Voltage gated ion channels are transmembrane proteins responsible for the generation and propagation of action potentials in excitable cells. They are key targets in receptor pharmacology, since the simple actions of opening and closing their pore with ...

C-terminal β9-strand of the cyclic nucleotide-binding homology domain stabilizes activated states of Kv11.1 channels. [PDF]

PLoS ONE, 2013
Kv11.1 potassium channels are important for regulation of the normal rhythm of the heartbeat. Reduced activity of Kv11.1 channels causes long QT syndrome type 2, a disorder that increases the risk of cardiac arrhythmias and sudden cardiac arrest.

Contribution of voltage‐gated potassium channels to the regulation of apoptosis [PDF]

FEBS Letters, 2010
Recent evidence points to the crucial involvement of voltage‐gated potassium channels (Kv) in apoptotic volume decrease and in the regulation of apoptosis in several systems. We have recently described the presence of a Kv channel, Kv1.3, in the mitochondria of lymphocytes.

The response of the tandem pore potassium channel TASK-3 (K2P9.1) to voltage : gating at the cytoplasmic mouth [PDF]

, 2009
Although the tandem pore potassium channel TASK-3 is thought to open and shut at its selectivity filter in response to changes of extracellular pH, it is currently unknown whether the channel also shows gating at its inner, cytoplasmic mouth through ...
