Notably, these included C207S, E221A, E267K, D293A, E297A, T298A, and E313A, residues that may contribute to the stability of the Aha1 interaction with Hsp90 (Figures 3 and 4B).

The charge-reversal mutations (E267R and K1060E) at these positions clearly had the most dramatic effects on CFTR activity (the E267K mutation also markedly inhibited CFTR activity; see Fig. 5).

status: NEW177 Conversely introducing a charge swap double mutation (E267K/K1060E) had no apparent effect on the basal currents and potentiator responses of this truncation construct (Fig. 7, C-E).
