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 Lambert-Eaton Myasthenic Syndrome. Among its related pathways are Integrin Pathway and Integration of energy metabolism. Gene Ontology (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 Summary 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.
