128 Further alignment showed that the R765Q mutation in ABCC6/MRP6 is the positional equivalent of both the R560T mutation in ABCC7,28 and the R842G mutation in ABCC8.29 Similarly, additional possible positional equivalent clusters of conserved and mutated residues were found between ABCC6/ MRP6 and ABCC2 (R1114H and R1150H),30 ABCC6/MRP6 and ABCC7 (3775 del T and W1204X),31 ABCC6/MRP6 and ABCR (R1459C and H2128R, 4220InsAGAA and R2077W, R1141X and L1631P).32,33 Interestingly, for both ABCC7 and ABCR, models were postulated in which the severity of the disease shows an inverse correlation with the predicted transport activity of the ABC protein.

1 Here, we investigate their mechanism of action by using biochemical and functional assays to examine their effects on F508del and three CF mutations (R560T, A561E, and V562I) located within a conserved region of the first nucleotide-binding domain (NBD1) of CFTR. Like F508del, R560T and A561E disrupt CFTR trafficking. Login to comment
2 G550E rescued the trafficking defect of A561E but not that of R560T. Login to comment
37 47 ͉ 17891-17896 and 4RK act by different mechanisms. To explore this possibility, we tested the effects of G550E and 4RK on three additional CF mutations within NBD1: R560T, A561E, and V562I.ʈ We selected for study these CF mutants because (i) these residues constitute a hot spot for disease-causing mutations (seven mutations are associated with these three residues࿣ ); (ii) A561E and R560T are the second and fourth most frequent mutations among Portuguese and Irish CF patients, respectively (28); (iii) like G550E and R555K (one of the 4RK mutants), these mutations affect residues located between the LSGGQ and Walker B motifs of NBD1, which are highly conserved across species; and (iv) they all lie within the same ␣-helix (H5; G550-Y563) within the ATP-binding cassette ␣-subdomain of NBD1 (29, 30).

38 To test the hypothesis that G550E and 4RK act by different mechanisms, we used biochemical and functional assays to investigate how these revertants rescue F508del-, R560T-, A561E-, and V562I-CFTR. Login to comment
39 Results R560T, but Not V562I, Disrupts the Processing of CFTR. Like F508del-CFTR, many CF mutations disrupt the processing of CFTR and its delivery to the cell surface. Login to comment
41 For the reasons outlined in the Introduction, we chose to analyze the CF mutations R560T, A561E, and V562I. Login to comment
43 Therefore, we first investigated the processing of R560T and V562I by using Western blot (WB). Login to comment
44 Fig. 1A demonstrates that like F508del- and A561E-CFTR, R560T-CFTR generated only a discrete Ϸ145 kDa band (band B). Login to comment
46 These data suggest that R560T, disrupts the trafficking of CFTR, whereas V562I-CFTR is delivered to the cell surface. Login to comment
47 Next, we investigated whether the revertants G550E and 4RK rescue the defective biosynthesis of R560T- and A561E-CFTR. Login to comment
55 The mature form of CFTR (band C) was clearly observed for F508del- and A561E-CFTR (Fig. 1D) in the presence of G550E and 4RK, but G550E failed to correct the defective biosynthesis of R560T-CFTR (Fig. 1 A and D). Login to comment
70 (A) WB of total protein (30 ␮g) from BHK cells stably expressing wt-, F508del-, R560T-, A561E-, or V562I-CFTR, alone or in cis with 4RK and G550E. Login to comment
75 (D) BHK cells expressing F508del-, R560T-, or A561E-CFTR alone or in cis with the revertants 4RK and G550E were analyzed by CFTR IP after pulse-labeling for 3 h. Labeled arrows indicate the positions of bands A, B, and C. Thus, the higher steady-state levels of band C for 4RK variants of both wtand V562I-CFTR (Fig. 1A) are explained only in part by a slight (but not significant) increase in the efficiency of processing band B to band C. Surprised that the revertants did not exert stronger effects on the processing of CFTR, we wondered how they might influence CFTR Cl-channel function. Login to comment
79 Consistent with the biochemical data (Fig. 1), these agonists had no effect on F508del-, R560T-, or A561E-CFTR (Fig. 3 B-D) but evoked a striking efflux of I- from V562I-CFTR (Fig. 3E), which has a time course equivalent to that of wt-CFTR and 1.3-fold greater (Fig. 3F). Login to comment
84 In contrast to F508del-CFTR, G550E did not restore CFTR function to R560T and both revertants rescued only modestly the CFTR function of A561E (Fig. 3 C, D, and F). Login to comment
96 (A-E) Time courses of I-efflux from BHK cells stably expressing wt- (A), F508del- (B), R560T- (C), A561E- (D), and V562I- (E) CFTR in the absence and presence of the 4RK and G550E mutations. Login to comment
127 Like F508del, R560T and A561E disrupt CFTR processing, whereas V562I traffics normally to the cell surface, forming a Cl-channel with properties indistinguishable from those of wt-CFTR. Login to comment
128 The revertants 4RK and G550E rescue the cell surface expression of A561E, albeit not as effectively as F508del, whereas G550E is without effect on R560T. Login to comment
129 Of note, G550E, but not 4RK, rescues the defective channel gating of F508del, suggesting that G550E and 4RK rescue the expression and function of F508del by distinct mechanisms. To understand the structural basis by which R560T and A561E disrupt the processing of CFTR (refs. Login to comment
132 R560T likely disrupts the interactions of R560 with neighboring residues and, hence, the folding of NBD1. Login to comment
205 When compared with both wtand F508del-CFTR, clones expressing V562I- and R560T-CFTR expressed higher and lower levels of protein, respectively, precluding studies on cell lines with equivalent amounts of CFTR protein. Login to comment

103 For example, the Intron 10/Exon 11 fragment spans 5 common mutation sites: 1717-1G Ǟ A, G542X, G551D, R553X, and R560T, while the ⌬I507 and ⌬F508 mutations in Exon 10 overlap by one basepair and each delete three basepairs. Login to comment
105 Because the G551D and R553X mutations are within four basepairs, these mutations were also synthesized on independently cloned Intron 10/Exon 11 fragments, both of which carried three other mutations: 1717-1G Ǟ A, G542X, and R560T (Fig. 2, fragments 1 and 3). Login to comment
165 As part of this validation, two different Intron10/Exon11 fragments were sequenced and tested: both contain the 1717-1G Ǟ A, G542X, and R560T mutations, and the first also contains the G551D mutation (Fig. 2, clone 1; Fig. 3, f1), while the second also contains the R553X mutation (Fig. 2, clone 3; Fig. 3, f3).

6 Ancient mutations, AF508, G542X, N1303K, were associated with several related haplotypes due to slippage during replication, whereas other common mutations were associated with the one respective haplotype (e.g., G551D and R560T with 16-7-17, R117H with 16-30-13,621+1G>T with 21-31-13,3659delC with 16-35-13).

58 As the repeat number increasesbeyond 50, it probably becomes more disposed to the addition or deletion of dinucleotide repeats during replication as all other mutations where several alleles were tested gave the same respective 17bTA repeat number, i.e., G551D (17AT repeats = 7), R560T (7), G85E (24), R117H (30), 621+1G>T (31), 3659delC (354, 1898+lG>A (45).

91 Other relativelycommon mutations (e.g., G551D, R560T, R117H, 3659delC, and 621+lG>T) were found associatedwith the one haplotype, suggesting that they emerged more recently. Login to comment
97 Another, 16-7-17, is highly sensitive, e.g., all G551D and R560T alleles tested were found on this framework, but has a low specificity as it is common in normals and is associated with 17 different mutations. Login to comment

69 For instance, table 2 shows that mutations G542X, 621 + 1G-T, N1303K, 3659delC, R560T, and Ri 17H are associated with the same haplotypes, or with haplotypes probably derived from these by slippage of the DNA polymerase, as has been seen in patients from other European populations.7'0 Since those haplotypes are relatively rare in normal chromosomes (table 3), the constancy of the association has been explained as suggesting identity by descent of all chromosomes bearing the same mutations.9 Haplotype 16-7-17 is found in CF non-AF508 chromosomes more frequently than would be expected from its frequency in normal chromosomes (p<0 01, table 3), suggesting perhaps that another fairly common CF mutation may be associated with this haplotype in Ireland.

10 This result is thus consistent with the hypothesis that PI and PS in CF are predisposed by the genotype at the CFTR locus; the PS phenotype occurs in patients who have one or two mild CFTR mutations, such as R117H, R334W, R347P, A455E, and P574H, whereas the PI phenotype occurs in patients with two severe alleles, such as AF508, A1507, Q493X, G542X, R553X, W1282X, 621 + 1G-PT, 1717-1G--'A, 556delA, 3659delC, I148T, G480C, V520F, G551D, and R560T.
