Figure 4. Effects of Tat on kinetic analysis of [3H]DA uptake in WT hDAT and His547 mutants.

Figure 4

PC12 cells transfected with WT hDAT (WT), H547A-hDAT (H547A), H547R-hDAT (H547R), H547D-hDAT (H547D), or Y551H-hDAT (Y551H) were preincubated with or without recombinant Tat1–86 (rTat1–86) (140 nM, final concentration) at room temperature for 20 min followed by the addition of [3H]DA. Nonspecific uptake was determined in the presence of 10 μM final concentration of nomifensine. Data are expressed as the ratio of the specific [3H]DA uptake in the presence of Tat to that in the absence of Tat [in DPM: WT hDAT (Tat, 4794 ± 989 vs control, 6858 ± 1393); H547A (Tat, 6190 ± 1474 vs control, 5799 ± 1408); H547R (Tat, 5026 ± 1097 vs control, 4698 ± 1257); H547D (Tat, 2159 ± 557 vs control, 2021 ± 565); and Y551H (Tat, 662 ± 107 vs control, 642 ± 108)] n = 7–8. *p < 0.05 compared with WT hDAT control values.
