Sodium channel β-subunit 4, also known as SCN4B or Naβ4, is an auxiliary sodium channel subunit that can alter the kinetics of sodium channels.[5] The protein is encoded by the SCN4B gene.[6] Mutations in the SCN4B are associated with long QT syndrome.[7]

SCN4B might additionally function as a cell adhesion molecule.[8][9]
