65 Mutations introduced by overlap extension PCR using Pfu AD DNA polymerase in ABCA1 included S100C, W590S, F593L, N935S, T929I, C1477R, T1512M, R2081W, and P2150L. Login to comment
66 Corresponding ABCA4 mutations determined by amino acid alignment with ABCA1 included S100P, W605S, F608L, T959I, N965S, C1502R, T1537M, R2107P, and P2180L. Login to comment

223 Finally, the null mutant C1502X associated with Stargardt disease was modified to C1502R to reflect the primary sequence change of the corresponding C1477R mutant in ABCA1 linked to Tangier disease. Login to comment
230 By contrast, the T1512M mutation in ECD2 and P2150L in the C-terminal segment exhibited ATPase activity similar to the WT protein. Login to comment
232 ABCA4 variants showed a similar ATPase activity profile as the ABCA1 mutants with the exception of the T1537M mutation of ABCA4, which was significantly lower than the corresponding T1512M mutant in ABCA1. Login to comment
234 As shown in Fig. 8, A and B, the Fl-PC flippase activity of the ABCA1 mutants and the Fl-PE flippase activity of ABCA4 mutants have a similar profile with the ABCA1 variants C1477R, T1512M, and P2150L and corresponding ABCA4 variants C1502R, T1537M, and P2180L showing transport activities ranging from 60 to 80% of the WT protein and the other mutants showing reduced activity in the range of 20-40% of the WT protein.

295 The ABCA1/ABCA4 mutants in the ECD1 (S100C/S100P, W590S/ W605S, and F593L/F608L) displayed the lowest activities (20-30% WT), whereas those in the ECD2 (C1477R/C1502R and T1512M/T1537M) and the P2150L/P2180L mutants in the C terminus showed the highest activities (60-100% WT). Login to comment
