PMA produces a large increase in conductance in a mutant hCFTR (H667R-hCFTR) with an engineered PKC consensus phosphorylation sequence that includes Thr665. (A) Representative I-V plot from an oocyte expressing H667R-hCFTR. (B) Summary of results from experiments such as those in A. Oocytes were primed with 25 μM 8-Br-cAMP. Data were obtained from six experiments. The results indicate that the engineered PKC consensus site is sufficient to confer a large response to PKC stimulation.
