57 The red balls show the locations of Trp232 and the processing mutations at positions 251 (G251V), 490 (ΔY490), 709 (P709A), 722 (G722A), and 1260 (L1260A). Login to comment
67 Mutations were introduced into wild-type P-gp or processing mutants containing processing mutations in different domains (G251V in TMD1, ΔY490 in NBD1, P709A in the linker region, G722A in TMD2, or L1260A in NBD2) as described previously (28). Login to comment
125 The W232R mutation was introduced into mutants P709A (linker region), G722A (TMD2), or L1260A (NBD2). Login to comment

58 Although mutation of only one of these residues (L975A, V981A and F983A) has no effect on the phenotype of the protein [20], double mutations either completely inhibit (V981A/F983A and L975A/V981A) or cause 50% inhibition (L975A/F983A) of Table 1. Login to comment

PMID: 15530432 [PubMed] Loo TW et al: "Thapsigargin or curcumin does not promote maturation of processing mutants of the ABC transporters, CFTR, and P-glycoprotein."

70 Although the processing mutations (G251V, G300V, DY490, P709A, G722A, F804A, and P1194A) are located in different segments of P-gp, all the mutants could be rescued when expressed with drug substrates such as cyclosporin A. Login to comment
90 We then compared the abilities of cyclosporin A, thapsigargin, and curcumin to induce maturation of P-gp processing mutants G251V, G300V, DY490, P709A, G722A, F804A, and P1194A. Login to comment

144 F, the P709A processing mutation wasintroducedintomutantF1086A.Mutantswereexpressedinthepresence (af9;) or absence (afa;) of verapamil (Ver), and whole cell extracts were subjected to immunoblot analysis. Login to comment
157 Accordingly, the F1086A mutation was introduced into the P709A processing mutant. Login to comment
158 The P709A mutant was selected because the mutation is located in the linker region that connects the two halves of P-gp and is outside the ATP-and drug-binding sites (Fig. 3, A and B). Login to comment
159 Expression of mutant P709A/ F1086A yielded the 150-kDa immature form of P-gp as the major product (Fig. 3F). Login to comment
