Thus, we identified six residues in 12b-NBD1 (E527Q, E528Q, S531T, K536Q, I539T, and K584E) and 12 residues in 114c-NBD2 (T1263I, P1290T, K1302Q, Y1307N, Q1309K, S1311K, R1325K, V1338T, C1344Y, L1367I, D1394G, and E1409D) (see supplemental Fig. 1 and supplemental Table 1, A and B).

status: NEW285 Among the 20 point mutants described in this study (the above 18 point mutants plus L581F and L581F/K584E), we found four that are listed in the CFTR mutation database (CFTR mutation database), namely E527Q, T1263I, and P1290T, which are described in association with mild CF, and I539T, which is described as an F508del-revertant mutation (Table 1).

status: NEW289 The most striking differences for the NBD1 mutants (Table 1 and Fig. 2, compare C with D) were (Iodide efflux to processed protein (%) far right column) E527Q (64/46), I539T (112/49), and L581F (118/72), whereas for the NBD2 mutants, they were T1263I (75/31), K1302Q (72/37), Q1309K (79/26), S1311K (73/33), V1338T (88/37), L1367I (72/36), and E1409D (70/43).
