378 M1137R interfered with the proper maturation of the protein and the whole cell cAMP activated chloride currents were reduced for M1137V, I1139V, D1152H and D1154G, indicating that these mutations interfere with the proper gating of chloride channels [180]. Login to comment

183 Thus, we asked to what extent can disease related folding defects caused by mutations in MSD1 (G85E, G91R, and V232D), MSD2 (M1137R), and NBD2 (N1303K) be corrected relative to those caused by deletion of F508 in NBD1 (Figure 4A). Login to comment
184 The G85E, G91R, M1137R, and N1303K mutations all hinder folding of the nascent B-form of CFTR via a mechanism that involves insertion of a charged amino acid into an inappropriate region (Gregory et al., 1991; Xiong et al., 1997; Vankeerberghen et al., 1998). Login to comment
190 The CFTR M1137R mutation exists within TM12 of CFTR`s MSD2 domain. Login to comment
192 Furthermore, chemical treatment of CFTR G91R or CFTR M1137R did not significantly affect the accumulation of the immature B-form; however, the mature C-forms of both CFTR G91R and CFTR M1137R were apparent. Login to comment
316 Corr-4a-dependent rescue of MSD biogenic mutants G91R and M1137R was no greater than that observed with corrector-treated CFTR⌬F508. Login to comment

123 Residual function also was observed for mutants, which are expected to form membrane Cl- channels that are reduced in number, either owing to improper protein maturation (P205S, M1137R) or owing to reduced levels of full-length CFTR messenger RNA (3272-26AϾG, G576A).32,38 - 40 The only exception was M1101K, which was reported as a loss of function mutation in heterologous cells34 and was associated with residual CFTR function in the 1 homozygous patient studied (Table 1).

1 Of the different mutations present in transmembrane helix 12 (M1137V, M1137R, I1139V and vvM1140), and the intracytoplasmic loop connecting TM12 and NBD2 (D1152H and D1154G), only M1137R interfered with the proper maturation of the protein. Login to comment
31 Six di¡erent mutations: a3541g ( = M1137V), t3542g ( = M1137R), a3547g ( = I1139V), deletion of atg from 3550 ( = vM1140), g3586c ( = D1152H) and a3593g ( = D1154G) were introduced using the Transformer Site-Directed Mutagenesis kit (Clontech). Login to comment

80 M1137V, M1137R, I1139V and vM1140 are located in transmembrane helix 12 and D1152H and D1154G are located in the intracytoplasmic loop connecting TM12 and NBD. Login to comment
83 Four mutants, M1137V, I1139V, D1152H and D1154G showed a signi'cantly reduced current, when compared to wild type, and two other mutants, M1137R and vM1140 were not activated by cAMP (Fig. 3). Login to comment
84 The absence of cAMP sensitive chloride currents found for M1137R is most probably caused by a defect in maturation, as found in COS1 cells. Login to comment
94 One mutation (M1137R) did result in failure of protein maturation while the remainder did a¡ect gating of the chloride channel. Login to comment
