It was observed that in the absence of VX-809, the V510D mutation significantly improved the maturation of Q207L, Q207C, Q207E, Q207N and Q207S (Fig. 6A and B).

status: NEW183 Mature CFTR was the major product in Q207N/V510D (90% mature product) while mutants Q207L/V510D, Q207C/V510D, Q207E/V510D, and Q207S/V510D showed modest levels of mature CFTR (about 20-40% mature).

status: NEW184 In the presence of corrector VX-809 however, the amount of mature CFTR in mutants V510D/Q207A V510D/Q207L, V510D/Q207C, V510D/Q207E, V510D/Q207F and V510D/Q207S were significantly increased (25-85% mature product).

status: NEW283 Furthermore, Gln207 itself appeared to be important for maturation since all mutations to Gln207, including the conservative changes Q207N and Q207E (Fig. 2) inhibited maturation of the protein.
