IV. Literature review

[source]
Gene nameSCN4B
Protein nameSodium channel subunit beta-4
Sodium channel beta-4 subunit (Sodium channel, voltage-gated, type IV, beta, isoform CRA_b) (cDNA, FLJ95353, Homo sapiens sodium channel, voltage-gated, type IV, beta (SCN4B),mRNA)
SynonymshCG_1646677
DescriptionFUNCTION: 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 susceptibility of the sodium channel to inhibition by toxic peptides from spider, scorpion, wasp and sea anemone venom. .
