Genetics update: monogenetics, polygene disorders and the quest for modifying genes [PDF]

open access: yes, 2018
The genetic channelopathies are a broad collection of diseases. Many ion channel genes demonstrate wide phenotypic pleiotropy, but nonetheless concerted efforts have been made to characterise genotype-phenotype relationships.

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

open access: yesБюллетень 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 ...

Mechanisms of Activation of Voltage-Gated Potassium Channels [PDF]

open access: yesActa Naturae, 2014
Voltage-gated potassium ion channels (Kv) play an important role in a variety of cellular processes, including the functioning of excitable cells, regulation of apoptosis, cell growth and differentiation, the release of neurotransmitters and hormones, maintenance of cardiac activity, etc.

Actions and Mechanisms of Polyunsaturated Fatty Acids on Voltage-Gated Ion Channels [PDF]

open access: yes, 2017
Polyunsaturated fatty acids (PUFAs) act on most ion channels, thereby having significant physiological and pharmacological effects. In this review we summarize data from numerous PUFAs on voltage-gated ion channels containing one or several voltage ...

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

open access: yesPLoS 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.

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.

Two-stage electro–mechanical coupling of a KV channel in voltage-dependent activation

open access: yesNature Communications, 2020
In voltage-gated potassium (KV) channels, the voltage-sensing domain (VSD) undergoes activation states to trigger pore opening via electro–mechanical (E–M) coupling. Here authors show that KV7.1 undergoes a two-stage E–M coupling mechanism during voltage-

Studies of Conorfamide-Sr3 on Human Voltage-Gated Kv1 Potassium Channel Subtypes

open access: yesMarine Drugs, 2020
Recently, Conorfamide-Sr3 (CNF-Sr3) was isolated from the venom of Conus spurius and was demonstrated to have an inhibitory concentration-dependent effect on the Shaker K+ channel.

Synthetic ShK-like Peptide from the Jellyfish Nemopilema nomurai Has Human Voltage-Gated Potassium-Channel-Blocking Activity

open access: yesMarine Drugs
We identified a new human voltage-gated potassium channel blocker, NnK-1, in the jellyfish Nemopilema nomurai based on its genomic information. The gene sequence encoding NnK-1 contains 5408 base pairs, with five introns and six exons.
