Protein Details: Voltage-gated sodium channel subunit beta-4

Protein ID

ICDB_Pro_0786

Protein Name

Voltage-gated sodium channel subunit beta-4

Gene Name

SCN4B

Organism

Bos taurus (Bovine)

Length

228 amino acids

AlphaFoldDB

AF-Q08E08-F1-model_v4.pdb

Function

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 (By similarity).
