There are a number of ELISA Kits available for the measurement of SCA6, another term for the human protein, calcium voltage-gated channel subunit alpha1 A. Other synonyms may include: voltage-dependent P/Q-type calcium channel subunit alpha-1A, brain calcium channel 1, brain calcium channel I, calcium channel voltage-dependent P/Q type alpha 1A subunit, voltage-gated calcium channel subunit alpha Cav2.1, APCA, and BI. It is encoded by the CACNA1A gene to yield a protein 2506 amino acids in length and 282.6 kDa in size. However, there are up to 6 reported isoforms. The protein is categorized into the Calcium channel alpha-1 subunit (TC 1.A.1.11) family, CACNA1A subfamily. Versions of SCA6 are present in other organisms, including: Mouse, Rat, Nematode.
