VKCDB: Voltage-gated potassium channel database
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 ...

Hysteresis in voltage-gated channels [PDF]
Channels, 2016 Ion channels constitute a superfamily of membrane proteins found in all living creatures. Their activity allows fast translocation of ions across the plasma membrane down the ion's transmembrane electrochemical gradient, resulting in a difference in electrical potential across the plasma membrane, known as the membrane potential.

KCNE1 and KCNE2 provide a checkpoint governing voltage-gated potassium channel α-subunit composition [PDF]
, 2011 Voltage-gated potassium (Kv) currents generated by N-type α-subunit homotetramers inactivate rapidly because an N-terminal ball domain blocks the channel pore after activation.

eLife, 2022 Tetrameric voltage-gated K+ channels have four identical voltage sensor domains, and they regulate channel gating. KCNQ1 (Kv7.1) is a voltage-gated K+ channel, and its auxiliary subunit KCNE proteins dramatically regulate its gating.

Voltage gating in porin channels [PDF]
FEBS Letters, 1987 Data from experiments in which porin channels are reconstituted into planar bilayer membranes are reviewed for their relevance to porin channel gating in vivo. Contradictory evidence concerning voltage gating indicates that the different results may stem from the variety of purification techniques employed.

Molecular mechanisms of the coupling of gating to voltage sensing in transmembrane proteins [PDF]
, 2014 Voltage gated potassium ion (Kv) channels regulate action potentials of the nervous system by responding to changes in transmembrane voltage, enabling K+ transport across the membrane to restore cells to their resting potential.

Developmental changes in voltage-gated calcium channel α(2)δ-subunit expression in the canine dorsal root ganglion [PDF]
, 2012 The voltage-gated calcium channel subunit (128 plays a fundamental role in propagation of excitatory signals associated with release of glutamate and neuropeptides substance P (SP) and calcitonin gene-related protein (CGRP).

Non-silent story on synonymous sites in voltage-gated ion channel genes. [PDF]
PLoS ONE, 2012 Synonymous mutations are usually referred to as "silent", but increasing evidence shows that they are not neutral in a wide range of organisms. We looked into the relationship between synonymous codon usage bias and residue importance of voltage-gated ...

Voltage-gated proton channels [PDF]
Cellular and Molecular Life Sciences, 2008 Voltage-gated proton channels, HV1, have vaulted from the realm of the esoteric into the forefront of a central question facing ion channel biophysicists, namely, the mechanism by which voltage-dependent gating occurs. This transformation is the result of several factors.
