The protein encoded by this gene is the beta 2 subunit of the type II voltage-gated sodium channel. The encoded protein is involved in cell-cell adhesion and cell migration. Defects in this gene can be a cause of Brugada Syndrome, atrial fibrillation, or sudden infant death syndrome. [provided by RefSeq, Jul 2015] See more...

GeneCards Summary for SCN2B Gene

SCN2B (Sodium Voltage-Gated Channel Beta Subunit 2) is a Protein Coding gene. Diseases associated with SCN2B include Atrial Fibrillation, Familial, 14 and Familial Atrial Fibrillation. Among its related pathways are Activation of cAMP-Dependent PKA and Developmental Biology. Gene Ontology (GO) annotations related to this gene include sodium channel regulator activity and voltage-gated sodium channel activity involved in cardiac muscle cell action potential. An important paralog of this gene is JAML.

UniProtKB/Swiss-Prot Summary for SCN2B Gene

  • 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 (By similarity).

Tocris Summary for SCN2B 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.

SCN2B_HUMAN
  • Atrial fibrillation, familial, 14 (ATFB14) [MIM:615378]: 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:19808477}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Note=Genetic variations in SCN2B may be involved in Brugada syndrome (PubMed:23559163). This tachyarrhythmia is 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 PubMed:23559163}.
