Protein

Sodium channel protein type 9 subunit alpha

Gene

Scn9a

Organism
Rattus norvegicus (Rat)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

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. It is a tetrodotoxin-sensitive Na+ channel isoform. Plays a role in pain mechanisms, especially in the development of inflammatory pain (By similarity).By similarity
