Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables voltage-gated sodium channel activity. Acts upstream of or within establishment of localization in cell and sodium ion transmembrane transport. Located in intercalated disc. Is expressed in brain; dorsal striatum; and ventral striatum. Human ortholog(s) of this gene implicated in long QT syndrome 10. Orthologous to human SCN4B (sodium voltage-gated channel beta subunit 4).
