156 Confocal images from representative xy sections taken from1of 3 independent experiments show the subcellular distribution of wild-type CFTR (WT), p.F508del mutant (F508del), and variants p.S50P (S50P), p.E60K (E60K), p.G85E (G85E), p.G85V (G85V), p.E92K (E92K), p.P5L (P5L), p.R75Q (R75Q), and p.Y89C (Y89C).

40 The eight CFTR variants included in this study: p.P5L, p.S50P, p.E60 K, p.R75Q, p.G85E, p.G85V, p.Y89C, and p.E92K (Fig. 1A) were generated by oligonucleotide-directed mutagenesis in pCMVCFTRNot6.2wt using the QuickChangeTM XL-Site-Directed Mutagenesis Kit (Stratagene, La Jolla, CA) according to the manufacturer`s instructions (see Supplementary Table S1 for a detailed description of the mutagenesis primers employed; available online at http://www.interscience.wiley.com/jpages/1059-7794/supp mat).

102 RESULTS Description and Cross-Species Analysis of Natural N-Terminus CFTR Variants We chose eight naturally occurring sequence variants, four located across the N-terminal CFTR tail (p.P5L, p.S50P, p.E60K, and p.R75Q), and four within the first segment of MSD1 (p.G85E, p.G85V, p.Y89C, and p.E92 K) (Fig. 1A; Table 1). Login to comment
110 In contrast, variants p.S50P, p.E60K, p.G85E, p.G85V, and p.E92K, produced only higher mobility band B proteins suggesting that, like the p.F508del mutant, the resulting misfolded channels are retained and degraded in the cytoplasm (Fig. 2A). Login to comment
118 B: Alignment of the N-terminus (amino acids 1 to 100) of the CFTR protein derived from di¡erent species.The sequences derived from human (Homo sapiens, Gen- BankNM_000492), mouse (Mus musculus,GenBankNM_021050), Norway rat (Rattusnovergicus,GenBankNM_031506), European rabbit (Oryctolagus cuniculus, GenBank NM_001082716), cow (Bos taurus, GenBank NM_174018), sheep (Ovis aries, GenBank NM_001009781), African clawed frog (Xenopus laevis, GenBank X65256), and spiny dog'sh (Squalus acanthias, GenBank M83785) were aligned using the ClustalW multiple sequence alignment program.The amino acid residue a¡ected by each of the variants analyzed (p.P5L, p.S50P, p.E60K, p.R75Q, p.G85E, p.G85V, p.Y89C, and p.E92K) is indicated in bold. Login to comment
122 Similarly, variants p.S50P, p.E60K, p.G85V, p.G85E, and p.E92K displayed a yellow colocalization pattern clearly compatible with retention of the anomalous CFTR proteins within the intracellular compartments and no detection of PM staining (Fig. 3). Login to comment
130 Likewise, none of the five variants (p.S50P, p.E60K, p.G85E, p.G85V, and p.E92K) in which severe misprocessing was previously demonstrated (Figs. 2 and 3), was able to generate cAMP-activated currents (Fig. 4B). Login to comment

213 Four of the variants (p.P5L, p.S50P, p.E60 K, and p.R75Q) are localized within the cytosolic N-terminal tail, and the remaining four (p.G85E, p.G85V, p.Y89C, and p.E92K) are embedded in three positions within the first transmembrane segment (TM1) of MSD1. Login to comment
215 Accordingly, using three different approaches (immunoblotting, immunocytochemistry, and electrophysiology) we found that 5 (p.S50P, p.E60K, p.G85E, p.G85V, and p.E92K) out of the 8 variants failed to mature, showing an analogous behavior than the most common F508del mutation. Login to comment
220 Moreover, although both p.G85E and p.G85V, similarly to p.E92K, do not appear to affect TM1 topology [Xiong et al., 1997], they are also localized within or adjacent to the bilayer. Login to comment
