Role of extracellular Ca(2+) in gating of Ca(V)1.2 channels
We examined changes in ionic and gating currents in Ca(V)1.2 channels when extracellular Ca(2+) was reduced from 10 mm to 0.1 μm. Saturating gating currents decreased by two-thirds (K(D)≈ 40 μm) and ionic currents increased 5-fold (K(D)≈ 0.5 μm) due to increasing Na(+) conductance. A biphasic time d...
