Batrachotoxin (BTX) is a steroidal amine derivative most commonly associated with poison dart frogs and is unique as a NaV ligand in that it alters every property of the channel, including threshold potential of
2). This enhancement of sodium channel inactivation causes the channels to become inactivated at potentials where they would normally be in the closed or resting state, and can be measured by examining the voltage dependence of channel availability. The enhanced inactivation can also contribute to a...
Voltage-gated sodium channels are expressed across excitable cells where they are crucial for sharp initiation dynamics and propagation of the action potential1. TheSCN5Agene encodes for the cardiac sodium channel α-subunit, Nav1.5.SCN5Amutations have been linked to cardiac arrhythmias such as Brugad...
Voltage-gated sodium channels (NaV) are responsible for the rapid depolarization of many excitable cells. They readily inactivate, a process where currents diminish after milliseconds of channel opening. They are also targets for a multitude of disease-causing mutations, many of which have been shown...
Excitable cells — including neurons, muscle cells and cardiac myocytes — are unique in expressing high densities of voltage-gated sodium (NaV) channels. This molecular adaptation enables these cells to produce action potentials, and is essential to the

Voltage-gated sodium channels are critical elements of action potential initiation and propagation in excitable cells because they are responsible for the initial depolarization of the membrane. These channels consist of a highly processed α subunit that is ∼260 kDa, associated with auxiliary β sub...
Advances in the structural analysis of voltage-gated sodium channels and other members of the voltage-gated cation channel superfamily [3], [4], [5] have identified specific structural elements that mediate the activation and inactivation gating events proposed by Hodgkin and Huxley [2]. The ...
