Effects of the distal C terminus on modulation of VDI by Mgi. Effect of Mgi on VDI in mean normalized current traces recorded from expression of (A) full-length CaV1.2, (B) truncated CaV1.2Δ1821, and (C) CaV1.2Δ1821 coexpressed with distal1822–2171. In A, n = 10 and 8 for 0.26 and 7.2 mM Mgi, respectively. In B, n = 10 and 7. In C, n = 5, 16, and 11 for 0.1, 0.26, and 7.2 mM Mgi, respectively.
