Summaries for SCN3B Gene

Entrez Gene Summary for SCN3B Gene

  • Voltage-gated sodium channels are transmembrane glycoprotein complexes composed of a large alpha subunit and one or more regulatory beta subunits. They are responsible for the generation and propagation of action potentials in neurons and muscle. This gene encodes one member of the sodium channel beta subunit gene family, and influences the inactivation kinetics of the sodium channel. Two alternatively spliced variants, encoding the same protein, have been identified. [provided by RefSeq, Jul 2008]

GeneCards Summary for SCN3B Gene

SCN3B (Sodium Voltage-Gated Channel Beta Subunit 3) is a Protein Coding gene. Diseases associated with SCN3B include Brugada Syndrome 7 and Brugada Syndrome. Among its related pathways are G-Beta Gamma Signaling and Cardiac conduction. GO annotations related to this gene include ion channel binding and voltage-gated sodium channel activity. An important paralog of this gene is SCN1B.

UniProtKB/Swiss-Prot for SCN3B Gene

  • Modulates channel gating kinetics. Causes unique persistent sodium currents. Inactivates the sodium channel opening more slowly than the subunit beta-1. 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 (By similarity).

Tocris Summary for SCN3B Gene

  • Voltage-gated sodium channels (NaV) are responsible for action potential initiation and propagation in excitable cells, including nerve, muscle, and neuroendocrine cell types. They are also expressed at low levels in non-excitable cells, where their physiological role is unclear.

  • Atrial fibrillation, familial, 16 (ATFB16) [MIM:613120]: A familial form of atrial fibrillation, a common sustained cardiac rhythm disturbance. Atrial fibrillation is characterized by disorganized atrial electrical activity and ineffective atrial contraction promoting blood stasis in the atria and reduces ventricular filling. It can result in palpitations, syncope, thromboembolic stroke, and congestive heart failure. {ECO:0000269 PubMed:20558140, ECO:0000269 PubMed:21051419}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Brugada syndrome 7 (BRGDA7) [MIM:613120]: A tachyarrhythmia characterized by right bundle branch block and ST segment elevation on an electrocardiogram (ECG). It can cause the ventricles to beat so fast that the blood is prevented from circulating efficiently in the body. When this situation occurs, the individual will faint and may die in a few minutes if the heart is not reset. {ECO:0000269 Ref.8}. Note=The disease is caused by mutations affecting the gene represented in this entry.
