Background	SCN2B plays a key role in the assembly, expression, and functional modulation of the heterotrimeric complex of the sodium channel. Voltage-gated sodium channels (NaV) are composed of one pore-forming alpha-subunit, which may be associated with either one or more beta-subunits. Alpha-subunits are composed for four homologous domains, each of which contains six transmembrane segments.They are responsible for action potential initiation and propagation in excitable cells, including nerve, muscle, and neuroendocrine cell types. SCN2B causes an increase in the plasma membrane surface area and in its folding into microvilli. SCN2B also interacts with TNR and may play a crucial role in clustering and regulation of activity of sodium channels at nodes of ranvier.
