status: NEW203 Because the G550E mutation replaces a Gly residue with the negatively charged Glu, we also constructed a CFTR⌬F/G550D variant to test whether the negative charge resulting from an aspartate substitution would have a similar effect on CFTR channel activation.

status: NEW208 CFTR⌬F/G550H and CFTR⌬F/G550D displayed 50 and 68% of CFTR⌬F/G550E Isc, respectively, demonstrating that these additional revertants were not as effective as G550E in suppressing the CFTR ⌬F508 defect.

status: NEW209 We tested the CFTR⌬F/G550D response to activation by low concentrations of forskolin (0.5 M) as described in Fig. 3.

status: NEW210 However, unlike the results observed for CFTR⌬F/ G550E, suboptimal forskolin concentration failed to activate CFTR⌬F/G550D (not shown).
