SCN2B

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.

Wikipedia summary for SCN2B:

Sodium channel subunit beta-2 is a protein that in humans is encoded by the SCN2B gene.

Human SCN2B Protein General Information

 

Protein names

Sodium channel subunit beta-2

Sequence length

215 AA.

Sequence similarities:

SCN2B belongs to the sodium channel auxiliary subunit SCN2B (TC 8.A.17) family. [View classification]. SCN2B contains 1 Ig-like C2-type (immunoglobulin-like) domain.

Subunit structure

The sodium channel consists of a pore-forming alpha subunit, beta-1 and beta-2 subunits. Beta-1 is non-covalently associated with alpha, while beta-2 is covalently linked by disulfide bonds. Interaction with SCN10A and TNR

Subcellular location: Membrane; Single-pass type I membrane protein.
Tissue specificity

Brain specific.
