Scn11a Gene Summary [Rat]
Enables voltage-gated sodium channel activity. Involved in membrane depolarization during action potential and optic nerve development. Located in axon. Is active in glutamatergic synapse and presynaptic membrane. Human ortholog(s) of this gene implicated in familial episodic pain syndrome 3 and hereditary sensory and autonomic neuropathy type 7. Orthologous to human SCN11A (sodium voltage-gated channel alpha subunit 11). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Scn11a often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
