Voltage-gated sodium channels: biophysics, pharmacology, and related channelopathies
Voltage-gated sodium channels (VGSC) are multi-molecular protein complexes expressed in both excitable and non-excitable cells. They are primarily formed by a pore-forming multi-spanning integral membrane glycoprotein (α-subunit) that can be associated ...

High-threshold mechanosensitive ion channels blocked by a novel conopeptide mediate pressure-evoked pain [PDF]
Little is known about the molecular basis of somatosensory mechanotransduction in mammals. We screened a library of peptide toxins for effects on mechanically activated currents in cultured dorsal root ganglion neurons.

Structure of a bacterial voltage-gated sodium channel pore reveals mechanisms of opening and closing [PDF]
Voltage-gated sodium channels are vital membrane proteins essential for electrical signalling; in humans, they are key targets for the development of pharmaceutical drugs. Here we report the crystal structure of an open-channel conformation of NavMs, the

Voltage-gated sodium channels dysfunction in depression: the hypothesis
Voltage-gated sodium (Na+) channels (VGSCs) are responsible for action potential initiation and propagation in most electrically excitable cells which are implicated in a wide range physiological functions including neuronal signalling, muscle ...

Potential roles of voltage-gated ion channel disruption in Tuberous Sclerosis Complex
Tuberous Sclerosis Complex (TSC) is a lynchpin disorder, as it results in overactive mammalian target of rapamycin (mTOR) signaling, which has been implicated in a multitude of disease states.

Voltage-Gated Sodium Channels as Insecticide Targets [PDF]
Voltage-gated sodium channels are critical for the generation and propagation of action potentials. They are the primary target of several classes of insecticides, including DDT, pyrethroids and sodium channel blocker insecticides (SCBIs). DDT and pyrethroids preferably bind to open sodium channels and stabilize the open state, causing prolonged ...

Noncanonical Roles of Voltage-Gated Sodium Channels
The Hodgkin-Huxley formulation, at its 60th anniversary, remains a bastion of neuroscience. Sodium channels Nav1.1-Nav1.3 and Nav1.6-Nav1.9 support electrogenesis in neurons and are often considered "neuronal," whereas Nav1.4 and Nav1.5 drive electrogenesis in skeletal and cardiac muscle.
