Identification
HMDB Protein ID CDBP04859
Secondary Accession Numbers Not Available
Name Neuronal acetylcholine receptor subunit alpha-2
Description Not Available
Synonyms Not Available
Gene Name CHRNA2
Protein Type Receptor
Biological Properties
General Function Involved in extracellular ligand-gated ion channel activity
Specific Function After binding acetylcholine, the AChR responds by an extensive change in conformation that affects all subunits and leads to opening of an ion-conducting channel across the plasma membrane
