Protein Details: Voltage-gated sodium channel subunit beta-3

Protein ID

ICDB_Pro_1247

Protein Name

Voltage-gated sodium channel subunit beta-3

Gene Name

SCN3B; QmoA-13657

Organism

Macaca fascicularis (Crab-eating macaque) (Cynomolgus monkey)

Length

215 amino acids

AlphaFoldDB

AF-Q8HXJ7-F1-model_v4.pdb

Function

Modulates channel gating kinetics. Causes unique persistent sodium currents. Inactivates the sodium channel opening more slowly than the subunit beta-1. Its association with NFASC may target the sodium channels to the nodes of Ranvier of developing axons and retain these channels at the nodes in mature myelinated axons (By similarity).
