Protein Details: Voltage-gated sodium channel subunit alpha Nav1.8

Protein ID

ICDB_Pro_1717

Protein Name

Voltage-gated sodium channel subunit alpha Nav1.8

Gene Name

SCN10A

Organism

Homo sapiens (Human)

Length

1956 amino acids

AlphaFoldDB

AF-Q9Y5Y9-F1-model_v4.pdb

Function

Tetrodotoxin-resistant channel that 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 sodium ions may pass in accordance with their electrochemical gradient. Plays a role in neuropathic pain mechanisms.
