Target Information

Voltage-gated sodium channels are selective ion channels that regulate the permeability of sodium ions in excitable cells. During the propagation of an action potential, sodium channels allow an influx of sodium ions, rapidly depolarizing the cell.
These channels consist of three glycoproteins: a pore-forming alpha subunit, a noncovalently associated beta1 subunit, and a disulfide-linked beta2 subunit. The beta subunits regulate channel expression, modulate gating, and function as cell adhesion molecules.
Alpha subunits of sodium channels type I and III are mainly expressed in neuronal cell bodies and proximal processes, while type II alpha subunits are more abundant along axons. The beta1 subunit of sodium channel type I is expressed in brain, skeletal, and cardiac muscle. In the brain, beta1 and beta2 are highly expressed in Purkinje cells, and beta1 is also found in pyramidal cells of the deep cerebellar nuclei.
Impaired voltage-gated sodium channels can lead to diseases such as myotonia.
