ML277 exclusively enhances the AO state voltage-sensing domain (VSD)-pore coupling of KCNQ1 channels, providing an effective tool to investigate the voltge-dependent gating and new strategies for treating long QT syndrome.
An integrative structural biology approach provides refined models of the KCNQ1-KCNE1 channel complex, which propose a new mechanism to explain how KCNE1 modulates KCNQ1 channel activation.
An auxiliary subunit alters the effect of a family of small-molecule openers on a voltage-gated potassium channel by inducing structural re-arrangements that promote protonation of the drug molecule.
The intermediate state conformation of the human KCNQ1 potassium channel voltage sensor domain was determined, validated, and shown to be conductive under physiological conditions.
Contrary to a generally accepted principle, the pore properties of KCNQ1 channels depend on the states of voltage-sensing domains activation; KCNE1 alters the voltage-sensing domains-pore coupling to modulate KCNQ1 channel properties.
Fatty acid analogues are interesting prototype compounds that may inspire the development of future IKs channel activators to treat patients with long QT syndrome caused by diverse arrhythmia-causing mutations in the IKs channel.
Sodium-activated potassium ion currents encoded by the kcnt1 gene delay action potential firing in DRG neurons by activity preceding an action potential.
The midbrain area for salience, reward and aversion in mouse brain harbours among the dopamine cells three subtypes somatostatin-expressing neurons that show combinatorial neurotransmitter phenotypes and interneuron properties.
Imprinted gene expression is set up during a critical window of early embryonic development, by the translation of parental imprints by oocyte-supplied Smchd1 into allele-specific gene silencing.
