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
239 In contrast, some of the mutants, including ABCA1 mutants T929I and R2081W and related ABCA4 mutants T959I and R2107P, showed partial or complete co-localization with calnexin in a reticular pattern characteristic of the ER. Login to comment

237 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.
