HMDB Protein ID HMDBP09079
Secondary Accession Numbers
  • 14823
Name Sodium channel subunit beta-1
Synonyms Not Available
Gene Name SCN1B
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-1 can modulate multiple alpha subunit isoforms from brain, skeletal muscle, and heart. Its association with neurofascin may target the sodium channels to the nodes of Ranvier of developing axons and retain these channels at the nodes in mature myelinated axons
