BackgroundVoltage-dependent calcium channels (VDCCs) are large (>400 kDa) heteromers which contain, minimally, three core subunits1,2/ , in a 1:1:1 stoichiometry1. Expression of VDCC gene products in Xenopus oocytes, or transfected cells shows that the1 subunits contain the ion channel pore while the auxiliary2/and subunits confer optimal cell surface expression and channel kinetics1. Until recently, the only exception to the above paradigm was the skeletal muscle VDCC, which, in addition to the1,2/ , core motif, also has an additional tightly associated integral membrane glycoprotein subunit termed1.Upon co-expression with the1.1,2/ 1,1a subunits of the skeletal muscle VDCC, subunits alter the peak currents, and the kinetics of channel activation and inactivation with the overall effect being a normalisation of currents to those resembling the endogenous channel2. Together, these results suggest that subunits modulate skeletal muscle VDCCs by stabilising their conformation. The4 subunit is specifically localized in the brain, with the2 and3 subunits.It shares >60% sequence homology with the2 and3 subunits and ~25% sequence homology with the1 and5 subunits.
