A Prokaryotic Voltage-Gated Sodium Channel
Science, 2001The pore-forming subunits of canonical voltage-gated sodium and calcium channels are encoded by four repeated domains of six-transmembrane (6TM) segments. We expressed and characterized a bacterial ion channel (NaChBac) from Bacillus halodurans that is encoded by one 6TM segment. The sequence,

Ubiquitylation of Voltage-Gated Sodium Channels
2014Ion channel proteins are regulated by different types of posttranslational modifications. The focus of this review is the regulation of voltage-gated sodium channels (Navs) upon their ubiquitylation. The amiloride-sensitive epithelial sodium channel (ENaC) was the first ion channel shown to be regulated upon ubiquitylation.

Voltage-Gated Sodium Channels and Pain
Current Drug Target -CNS & Neurological Disorders, 2004Voltage-gated sodium channels are highly specialized molecular transducers that play a significant role in the creation and transmission of electrical activity throughout the neuraxis. These ion channels are fundamentally involved in sensory neuron physiology and pathophysiology; a complete but localized suspension of their normal function can prevent ...

Structural Pharmacology of Voltage-Gated Sodium Channels
Journal of Molecular Biology, 2021Voltage-gated sodium (NaV) channels initiate and propagate action potentials in excitable tissues to mediate key physiological processes including heart contraction and nervous system function. Accordingly, NaV channels are major targets for drugs, toxins and disease-causing mutations.

Voltage-Gated Sodium Channels in Neurological Disorders
CNS & Neurological Disorders - Drug Targets, 2008Voltage-gated sodium channels play an essential biophysical role in many excitable cells such as neurons. They transmit electrical signals through action potential (AP) generation and propagation in the peripheral (PNS) and central nervous systems (CNS). Each sodium channel is formed by one alpha-subunit and one or more beta-subunits.

Risperidone inhibits voltage-gated sodium channels
European Journal of Pharmacology, 2014In contrast to several other antipsychotic drugs, the effects of the atypical antipsychotic risperidone on voltage-gated sodium channels have not been characterized yet, despite its wide clinical use. Here we performed whole-cell voltage-clamp recordings to analyze the effects of risperidone on voltage-dependent sodium currents of N1E-115 mouse ...

Conotoxin modulation of voltage-gated sodium channels
The International Journal of Biochemistry & Cell Biology, 2008The rising phase of the action potential in excitable cells is mediated by voltage-gated sodium channels (VGSCs), of which there are nine mammalian subtypes with distinct tissue distribution and biophysical properties. The involvement of certain VGSC subtypes in disease states such as pain and epilepsy highlights the need for agents that modulate VGSCs

Voltage-Gated Sodium Channel Blockers as Immunomodulators
Recent Patents on CNS Drug Discovery, 2006Several Voltage-Gated Sodium Channels (VGSC) are widely expressed on lymphocytes and macrophages but their role in immune function is still debated. Nevertheless, Na(+) influx through VGSC is required for lymphocytes activation and proliferation, since these responses are blocked by Na(+)-free medium or by VGSC blockers.

Voltage-gated sodium channels as therapeutic targets
Drug Discovery Today, 2000Voltage-gated sodium channels (VGSCs) play a central role in the generation and propagation of action potentials in neurons and other cells. VGSC modulators have their origins in empirical pharmacology and are being used as local anaesthetics, antiarrhythmics, analgesics and antiepileptics, and for other disorders.
