Identification
HMDB Protein ID CDBP04272
Secondary Accession Numbers Not Available
Name Sodium channel protein type 2 subunit alpha
Description Not Available
Synonyms
  1. HBSC II
  2. Sodium channel protein brain II subunit alpha
  3. Sodium channel protein type II subunit alpha
  4. Voltage-gated sodium channel subunit alpha Nav1.2
Gene Name SCN2A
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
