Gene: SCN1B (sodium voltage-gated channel beta subunit 1) Homo sapiens
Symbol: SCN1B
Name: sodium voltage-gated channel beta subunit 1
CRRD ID: 1350483
Description: Exhibits sodium channel regulator activity and voltage-gated sodium channel activity involved in Purkinje myocyte action potential. Involved in several processes, including cardiac conduction; regulation of atrial cardiac muscle cell membrane depolarization; and regulation of sodium ion transport. Localizes to voltage-gated sodium channel complex. Implicated in Brugada syndrome 5; early infantile epileptic encephalopathy 52; familial atrial fibrillation; and generalized epilepsy with febrile seizures plus 1.
Type: protein-coding
RefSeq Status: REVIEWED
