VKCDB: Voltage-gated potassium channel database [PDF]
BMC Bioinformatics, 2004 Background The family of voltage-gated potassium channels comprises a functionally diverse group of membrane proteins. They help maintain and regulate the potassium ion-based component of the membrane potential and are thus central to many critical ...

Mechanism of electromechanical coupling in voltage-gated potassium channels [PDF]
Frontiers in Pharmacology, 2012 Voltage-gated ion channels play a central role in the generation of action potentials in the nervous system. They are selective for one type of ion – sodium, calcium or potassium. Voltage-gated ion channels are composed of a central pore that allows ions

Voltage-Gated Potassium Channels as Regulators of Cell Death [PDF]
Frontiers in Cell and Developmental Biology, 2020 Ion channels allow the flux of specific ions across biological membranes, thereby determining ion homeostasis within the cells. Voltage-gated potassium-selective ion channels crucially contribute to the setting of the plasma membrane potential, to volume

The structure of a voltage gated potassium channel [PDF]
, 2010 Voltage gated potassium channels (Kv channels) are tetrameric ion channels, responsible for regulating the potassium component of the membrane potential in a large range of cell types ranging from mammalian excitable cells to bacteria. Attempts have been made to elucidate the structure of voltage gated potassium channels using X-ray crystallography ...

Structural and functional modularity of voltage‐gated potassium channels [PDF]
FEBS Letters, 1999 Sequence similarity among known potassium channels indicates the voltage‐gated potassium channels consist of two modules: the N‐terminal portion of the channel up to and including transmembrane segment S4, called in this paper the ‘sensor’ module, and the C‐terminal portion from transmembrane segment S5 onwards, called the ‘pore’ module.
