Figure 5. dCT and AKAP15 do not alter the cAMP‐dependent increase in I Ba .
A, coexpression of dCT and AKAP15 does not alter the cAMP effect on CaV1.2Δ1821. Oocytes were injected with 1 ng RNA of CaV1.2Δ1821 and the indicated amounts of dCT and AKAP15 RNAs (summary of 5 experiments). B, coexpression of EGFP‐labelled Ht31 (5 ng RNA) does not affect the regulation of CaV1.2Δ1821 (1 ng RNA). Expression of EGFP‐Ht31 was confirmed by measuring fluorescence in intact oocytes. Summary from 2 experiments is shown.
