背景
Voltage-gated sodium channels are transmembrane glycoprotein complexes composed of a
large alpha subunit and one or more regulatory beta subunits .They are responsible for the
generation and propagation of action potentials in neurons and muscle .This gene encodes
one member of the sodium channel beta subunit gene family, and influences the inactivation
kinetics of the sodium channel .Two alternatively spliced variants, encoding the same
protein, have been identified .
