Scientific Background
Voltage-gated sodium channels (NaV) are essential for the generation of action potentials and for cell excitability.1 NaV channels are activated in response to depolarization and selectively allow flow of Na+ ions.
To date, nine NaV α subunits have been cloned and named NaV1.1-NaV1.9.4-5 The NaV channels are classified into two groups according to their sensitivity to Tetrodotoxin (TTX): TTX-sensitive (NaV1.1, NaV1.2, NaV1.3, NaV1.4, NaV1.6 and NaV1.7) and TTX-resistant (NaV1.5, NaV1.8 and NaV1.9).2-3 Mammalian sodium channels are heterotrimers, composed of a central, pore-forming α subunit and two auxiliary β subunits. The expression of the α subunit isoform is developmentally regulated and tissue specific.
