Identification
HMDB Protein ID CDBP04270
Secondary Accession Numbers Not Available
Name Sodium channel protein type 1 subunit alpha
Description Not Available
Synonyms
  1. Sodium channel protein brain I subunit alpha
  2. Sodium channel protein type I subunit alpha
  3. Voltage-gated sodium channel subunit alpha Nav1.1
Gene Name SCN1A
Protein Type Transporter
Biological Properties
General Function Involved in ion channel activity
Specific 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
