β-Arrestin-Mediated Regulation of the Human Ether-a-go-go-Related Gene Potassium Channel [PDF]

open access: yesMolecular Pharmacology, 2017
The rapidly activating delayed rectifier K+ channel (IKr) is encoded by the human ether-a-go-go-related gene (hERG), which is important for the repolarization of the cardiac action potential. Mutations in hERG or drugs can impair the function or decrease the expression level of hERG channels, leading to long QT syndrome.

Rac and Rho Mediate Opposing Hormonal Regulation of the Ether-A-Go-Go-Related Potassium Channel [PDF]

open access: yesCurrent Biology, 2002
Previous studies of ion channel regulation by G proteins have focused on the larger, heterotrimeric GTPases, which are activated by heptahelical membrane receptors. In contrast, studies of the Rho family of smaller, monomeric, Ras-related GTPases, which are activated by cytoplasmic guanine nucleotide exchange factors, have focused on their role in ...

Eag1 Channels as Potential Cancer Biomarkers

open access: yesSensors, 2012
Cancer is a leading cause of death worldwide. New early tumor markers are needed to treat the disease at curable stages. In addition, new therapeutic targets are required to treat patients not responding to available treatments.

Emerging roles for ether‐á‐go‐go‐related gene potassium channels in the brain

open access: yesThe Journal of Physiology, 2008
Voltage-activated ether-a-go-go-related gene (ERG1a, Kv11) potassium channels play a prominent role in regulating cardiac excitability and in heart disease. Recently, ERG channels were found to be widely distributed in brain (Papa et al. 2003; Guasti et al. 2005), although little is currently known regarding their functional role in the nervous system.

Regulation of Deactivation by an Amino Terminal Domain in Human Ether-à-go-go –related Gene Potassium Channels

open access: yesThe Journal of General Physiology, 1998

The molecular determinants of R-roscovitine block of hERG channels.

open access: yesPLoS ONE, 2019
Human ether-à-go-go-related gene (Kv11.1, or hERG) is a potassium channel that conducts the delayed rectifier potassium current (IKr) during the repolarization phase of cardiac action potentials. hERG channels have a larger pore than other K+channels and

Natural antisense transcripts regulate the neuronal stress response and excitability

open access: yeseLife, 2014
Neurons regulate ionic fluxes across their plasma membrane to maintain their excitable properties under varying environmental conditions. However, the mechanisms that regulate ion channels abundance remain poorly understood.

Electropharmacological Effects of a Spironolactone Derivative, Potassium Canrenoate, Assessed in the Halothane-Anesthetized Canine Model

open access: yesJournal of Pharmacological Sciences, 2004
While aldosterone receptor blockers improve survival of patients with congestive heart failure, spironolactone and its derivatives were recently shown to block ether-a-go-go-related gene (HERG) channels and native IKs and IKr currents in guinea pig ...

The Study on the hERG Blocker Prediction Using Chemical Fingerprint Analysis

open access: yesMolecules, 2020
Human ether-a-go-go-related gene (hERG) potassium channel blockage by small molecules may cause severe cardiac side effects. Thus, it is crucial to screen compounds for activity on the hERG channels early in the drug discovery process.

Inhibition of the hERG Potassium Channel by a Methanesulphonate-Free E-4031 Analogue

open access: yesPharmaceuticals, 2023
hERG (human Ether-à-go-go Related Gene)-encoded potassium channels underlie the cardiac rapid delayed rectifier (IKr) potassium current, which is a major target for antiarrhythmic agents and diverse non-cardiac drugs linked to the drug-induced form of ...
