Summaries for CACNB2 Gene

Entrez Gene Summary for CACNB2 Gene

  • This gene encodes a subunit of a voltage-dependent calcium channel protein that is a member of the voltage-gated calcium channel superfamily. The gene product was originally identified as an antigen target in Lambert-Eaton myasthenic syndrome, an autoimmune disorder. Mutations in this gene are associated with Brugada syndrome. Alternatively spliced variants encoding different isoforms have been described. [provided by RefSeq, Feb 2013]

GeneCards Summary for CACNB2 Gene

CACNB2 (Calcium Voltage-Gated Channel Auxiliary Subunit Beta 2) is a Protein Coding gene. Diseases associated with CACNB2 include Brugada Syndrome 4 and Brugada Syndrome. Among its related pathways are NFAT and Cardiac Hypertrophy and TCR Signaling (Qiagen). GO annotations related to this gene include calcium channel activity and high voltage-gated calcium channel activity. An important paralog of this gene is CACNB1.

UniProtKB/Swiss-Prot for CACNB2 Gene

  • The beta subunit of voltage-dependent calcium channels contributes to the function of the calcium channel by increasing peak calcium current, shifting the voltage dependencies of activation and inactivation, modulating G protein inhibition and controlling the alpha-1 subunit membrane targeting.

  • Brugada syndrome 4 (BRGDA4) [MIM:611876]: A heart disease characterized by the association of Brugada syndrome with shortened QT intervals. Brugada syndrome is 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 PubMed:17224476}. Note=The disease is caused by mutations affecting the gene represented in this entry.
