• Function: Mediates the voltage-dependent sodium ion permeability of excitable membranes. Assuming opened or closed conformations in response to the voltage difference across the membrane, the protein forms a sodium-selective channel through which Na(+) ions may pass in accordance with their electrochemical gradient.
• KEGG Pathway: Taste transduction (hsa04742)
• Reactome Pathway:
  Phase 0 - rapid depolarisation (R-HSA-5576892)
  Sensory perception of sweet, bitter, and umami (glutamate) taste (R-HSA-9717207)
  Interaction between L1 and Ankyrins (R-HSA-445095)
