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 {ECO:0000250}; Single-pass type I membrane protein {ECO:0000250}.
