Protein Details: Voltage-gated sodium channel subunit alpha Nav1.6

Protein ID

ICDB_Pro_0274

Protein Name

Voltage-gated sodium channel subunit alpha Nav1.6

Gene Name

Scn8a

Organism

Rattus norvegicus (Rat)

Length

1978 amino acids

AlphaFoldDB

AF-O88420-F1-model_v4.pdb

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.
