Voltage-Gated Sodium Channel beta-4 Subunit
SCN4B Sodium Channel beta Subunit
Voltage Gated Sodium Channel beta 4 Subunit
A voltage-gated sodium channel beta subunit subtype that covalently associates with voltage-gated alpha subunits. Defects in the SCN4B gene, which codes for this beta subunit, are associated with long QT syndrome-10.
