Binding properties of Rab8A and thiophosphorylated Rab8A to PPM1H. A and B , thiophosphorylated Rab8A Q67L does not rely on L66 for PPM1H binding. C and D , thio-phosphorylated Q67L Rab8A but not nonphosphorylated Rab8A binds much less tightly to a PPM1H FLAP domain mutated PPM1H R338A. E and F , GTP-bound WT Rab8A binds more strongly than GDP-bound WT Rab8A to PPM1H. Various Rab8A or pRab8A proteins were serially diluted and incubated with 100 nM mNeon PPM1H variants as in . Graphs represent mean ± SD from three independent experiments using separate protein preparations. pRab, phosphoRab.

$Rab8A associates with liposome-bound PPM1H. Sucrose gradient coflotation of His-Rab8A Q67L (full length, nonprenylated) with mNeon PPM1H ( A , B ) or mNeon L66R PPM1H ( C , D ) in the presence and absence of 50 nm liposomes. The distribution of PPM1H and Rab8A across the gradient was determined by immunoblot; fractions were collected from the top . Quantification of three independent experiments is shown (±SD).$

Rab8A, but not Rab12, inhibits PPM1H activity. A , anti-pRab10 immunoblot analysis of dephosphorylation by PPM1H ( upper gel ) or L66R PPM1H ( lower gel ). B and C , data were plotted as PPM1H activity, with maximum activity equal to the amount of pRab10 dephosphorylation seen in the absence of non-pRab inhibitor (lanes 3 and 4 of each gel) compared with reactions lacking PPM1H (lanes 1 and 2). D , rate of pRab10 phosphatase activity (monitored at t = 0, 8, 15, and 30 min) for mNeon-PPM1H, mNeon-L66R PPM1H, and mNeon Δ37 PPM1H. E , quantification of pRab10 intensity from ( D ), with maximum intensity detected at 0 min normalized to a value of 1. Error bars represent SD from three independent experiments; representative gels are shown. Black line , mNeon L66R PPM1H activity; red line , mNeon PPM1H activity; and blue line , mNeon Δ37 PPM1H activity. pRab, phosphoRab.
