Gene: CACNB2 (calcium voltage-gated channel auxiliary subunit beta 2) Homo sapiens
Symbol: CACNB2
Name: calcium voltage-gated channel auxiliary subunit beta 2
Description: Exhibits voltage-gated calcium channel activity. Contributes to high voltage-gated calcium channel activity and voltage-gated calcium channel activity involved in AV node cell action potential. Involved in calcium ion import; cardiac conduction; and positive regulation of calcium ion transport. Localizes to the L-type voltage-gated calcium channel complex. Implicated in Brugada syndrome 4; hypertension; and hypertrophic cardiomyopathy.
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
