SCN2A Products

Description

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, which rapidly depolarize the cell. The three glycoproteins that comprise the voltagegated sodium channel proteins include a pore-forming alpha subunit, a noncovalently associated beta1 subunit and a disulfide-linked beta2 subunit. The two beta subunits regulate the level of channel expression, modulate gating and function as cell adhesion molecules for cellular aggregation and cytoskeleton interaction. The alpha subunits of sodium channels type I and III are predominantly expressed in neuronal cell bodies and proximal processes, while type IIalpha 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 expressed in the pyramidal cells of the deep cerebellar nuclei. Impaired voltage-gated sodium channels lead to a number of diseases including myotonia.
