Identification
HMDB Protein ID HMDBP09081
Secondary Accession Numbers
  • 14825
Name Sodium channel subunit beta-2
Synonyms Not Available
Gene Name SCN2B
Protein Type Unknown
Biological Properties
General Function Involved in voltage-gated sodium channel activity
Specific Function Crucial in the assembly, expression, and functional modulation of the heterotrimeric complex of the sodium channel. The subunit beta-2 causes an increase in the plasma membrane surface area and in its folding into microvilli. Interacts with TNR may play a crucial role in clustering and regulation of activity of sodium channels at nodes of Ranvier
