SCN2B encodes the beta-2 auxiliary subunit of voltage-gated sodium channels[1]. These auxiliary subunits play critical roles in modulating the trafficking, localization, and functional properties of the pore-forming alpha subunits. Sodium channels are essential for action potential generation and propagation in excitable cells including neurons and cardiomyocytes.
The Navβ2 subunit (encoded by SCN2B) modulates sodium channel function in several ways:
In the nervous system, proper sodium channel function is essential for:
Mutations in SCN2B have been linked to several neurological conditions[2]:
SCN2B is expressed in:
Understanding SCN2B function informs:
