Data Sheet Data Sheet Data Sheet Data Sheet Material Safety Data Sheet (MSDS)

The sodium channel protein type 9 subunit alpha gene, SCN9A, is responsible for regulating Na+ ion permeability across excitable membranes. Found on chromosome 2, SCN9A mediates the passage of Na+ ions through the formation of an alpha subunit, known as Nav1.7, in voltage-gated sodium channels primarily expressed in neurones belonging to the peripheral nervous system.

Sodium channels synthesised under the action of SCN9A originate from the Degenerin/epithelial (Deg/ENaC) ion channel superfamily that shares common organisational features, including an extracellular loop accompanied by a conserved cysteine-rich region, two membrane-spanning segments and two intracellular carboxyl and amino termini. Members of this family, and their respective alpha, beta and gamma isoforms, are associated with maintaining transepithelial sodium balance in the kidneys, lungs and colon.

The widespread expression of Nav1.7 at peripheral terminals of intraepidermal nerve fibres makes them a likely contributor to axonal conduction and presynaptic neurotransmitter release in nociceptors. In humans, loss-of-function mutations in SNC9A have been linked to congenital insensitivity to pain (CIP) and anosmia.
