Identification
HMDB Protein ID CDBP04275
Secondary Accession Numbers Not Available
Name Sodium channel subunit beta-3
Description Not Available
Synonyms Not Available
Gene Name SCN3B
Protein Type Enzyme
Biological Properties
General Function Involved in voltage-gated sodium channel activity
Specific 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 neurofascin may target the sodium channels to the nodes of Ranvier of developing axons and retain these channels at the nodes in mature myelinated axons
