Protein: Sodium channel protein type 9 subunit alpha (Peripheral sodium channel 1) (PN1) (Sodium channel protein type IX subunit alpha) (Voltage-gated sodium channel subunit alpha Nav1.7) (Q62205)
Organism: Mus musculus (Mouse)
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. It is a tetrodotoxin-sensitive Na(+) channel isoform. Plays a role in pain mechanisms, especially in the development of inflammatory pain.
Subcellular location: Cell membrane {ECO:0000269|PubMed:15123669}; Multi-pass membrane protein {ECO:0000250|UniProtKB:Q15858}. Cell projection, neuron projection {ECO:0000250|UniProtKB:Q15858}.
