Last Modified 2014-10-13 [Report errors or provide feedback]
Gene Symbol SCN3B
Protein Name Sodium channel subunit beta-3
Synonyms
Species Bos taurus
Ensembl Protein ENSBTAP00000022302
InnateDB Gene IDBG-632273 (SCN3B)
Protein Structure
UniProt Annotation
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 (By similarity). {ECO:0000250}.
Subcellular Localization Membrane; Single-pass type I membrane protein.
