  • Target

    • Function

      The alpha-2/delta subunit of voltage-dependent calcium channels regulates calcium current density and activation/inactivation kinetics of the calcium channel. Acts as a regulatory subunit for P/Q-type calcium channel (CACNA1A), N-type (CACNA1B), L-type (CACNA1C OR CACNA1D) and possibly T-type (CACNA1G). Overexpression induces apoptosis.
    • Tissue specificity

      Predominantly present in cerebellar cortex. Present in various lung tumor cell lines, while it is absent in normal lung (at protein level). Highly expressed in heart, lung, testis, pancreas and skeletal muscle. Also expressed in kidney, liver, placenta and brain.
    • Sequence similarities

      Belongs to the calcium channel subunit alpha-2/delta family.
      Contains 1 cache domain.
      Contains 1 VWFA domain.
    • Domain

      The MIDAS-like motif in the VWFA domain binds divalent metal cations and is required to promote trafficking of the alpha-1 (CACNA1) subunit to the plasma membrane by an integrin-like switch.
    • Post-translational

      May be proteolytically processed into subunits alpha-2-2 and delta-2 that are disulfide-linked. It is however unclear whether such cleavage really takes place in vivo and has a functional role.
    • Cellular localization

      Membrane. Colocalizes with CACNA1A in lipid raft fractions.

      ab173293 was shown to specifically react with CACNA2D2 when CACNA2D2 knockout samples were used. Wild-type and CACNA2D2 knockout samples were subjected to SDS-PAGE. ab173293 and ab8245 (loading control to GAPDH) were diluted at 1/5000 and 1/10000 respectively and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed ab216776 secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.
