What is the function of this protein?
Mediates the voltage-dependent sodium ion permeability of excitable membranes (PubMed:16921370, PubMed:17928448, PubMed:27281198).  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.  Plays a key role in brain, probably by regulating the moment when neurotransmitters are released in neurons (PubMed:16921370, PubMed:22914087).  Involved in sensory perception of mechanical pain: activation in somatosensory neurons induces pain without neurogenic inflammation and produces hypersensitivity to mechanical, but not thermal stimuli (PubMed:27281198).
What are the official names of this protein?
Sodium channel protein type 1 subunit alpha, Sodium channel protein brain I subunit alpha, Sodium channel protein type I subunit alpha, Voltage-gated sodium channel subunit alpha Nav1.1.
What is the protein family that this protein belongs to?
Belongs to the sodium channel (TC 1.A.1.10) family. Nav1.1/SCN1A subfamily.
What are the subcellular locations of this protein?
Cell membrane; Multi-pass membrane protein.
