    Scientific background

    The α2δ1 protein, encoded by CACNA2D1, is an auxiliary subunit of the CaV (voltage-dependent calcium) channel multimer complex. Four α2δ isoforms were identified in mammalian genomes. They share some sequence, as well as structure, homology.1

    The protein product of the gene encoding α2δ is complex; it includes two separated proteins - the extracellular α2 peptide linked by disulfide bridges to the membrane spanning (single transmembrane helix) δ subunit.

    The α2δ1 subunit is highly expressed in skeletal muscle and brain. Its expression along with a pore forming CaV αsubunit, result in larger CaV currents, probably due to improved trafficking of the α1 subunit to the plasma membrane.1-2 α2δsubunit was shown to be the target of the antiepileptic and analgesic drug Gabapentin.3
