Effects of mutations at Y1219 on the response of G551D-CFTR to ATP washout. (A–C) Real-time current traces in response to ATP removal for G551D/Y1219F (A), G551D/Y1219I (B), and G551D/Y1219G (C). (D) Summary of the ratios between the peak current after ATP washout (IPEAK) and the steady-state current before ATP removal (IATP) for G551D and its variants. Mean ± SEM is shown.
