Literature associating SCN4B and long QT syndrome 13
Sodium channel, voltage-gated, type IV, beta subunit; Modulates channel gating kinetics. Causes negative shifts in the voltage dependence of activation of certain alpha sodium channels, but does not affect the voltage dependence of inactivation. Modulates the suceptibility of the sodium channel to inhibition by toxic peptides from spider, scorpion, wasp and sea anemone venom; Sodium voltage-gated channel beta subunits
Synonyms: SCN4B, SCN4Bp, hSCN4B, B0YJ93, Q8IWT1 ...
