Gene: CACNA1G (calcium voltage-gated channel subunit alpha1 G) Homo sapiens
Symbol: CACNA1G
Name: calcium voltage-gated channel subunit alpha1 G
Description: Exhibits low voltage-gated calcium channel activity and scaffold protein binding activity. Involved in calcium ion import; calcium ion transmembrane transport; and regulation of membrane potential. Localizes to the cytoplasm and plasma membrane. Implicated in hereditary ataxia.
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: Ca(V)T.1; calcium channel, voltage-dependent, alpha 1G subunit; calcium channel, voltage-dependent, T type, alpha 1G subunit; calcium channel, voltage-dependent, T type, alpha-1G subunit; Cav3.1; cav3.1c; MGC117234; NBR13; SCA42; SCA42ND; voltage-dependent calcium channel alpha 1G subunit, isoform 11; voltage-dependent T-type calcium channel alpha 1G subunit; voltage-dependent T-type calcium channel subunit alpha-1G; voltage-gated calcium channel subunit alpha Cav3.1
