Gene: CACNB2 (calcium voltage-gated channel auxiliary subunit beta 2) Homo sapiens
Symbol: CACNB2
Name: calcium voltage-gated channel auxiliary subunit beta 2
Description: 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]
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: CAB2; CACNLB2; calcium channel voltage-dependent subunit beta 2; calcium channel, voltage-dependent, beta 2 subunit; CAVB2; FLJ23743; lambert-Eaton myasthenic syndrome antigen B; myasthenic (Lambert-Eaton) syndrome antigen B; MYSB; voltage-dependent L-type calcium channel subunit beta-2
