The mutant channels CFTR-F429C, F430C, F433C, and F1232C showed no difference from wild-type CFTR, indicating that either the residues were not accessible to modification, or cysteine modification did not affect function.

status: NEW77 When expressed in HeLa cells, CFTR-F429C, F430C, F433C, F446C, Y1219C, and F1232C all generated Cl-channel activity in excised, inside-out patches of membrane.

status: NEW114 A summary of these data is shown in Fig. 4B. Wild-type, CFTR-F429C, F430C, F433C, and F1232C all exhibited similar levels of activity after treatment with 200 M MTSET in the absence of ATP.
