Role of PH domains for PtdIns(3,4,5)P3-independent GAP activity. A, activity with LUVs lacking PtdIns(3,4,5)P3. PH1-Ank and ArfGAP-Ank were titrated into reaction mixtures containing myrArf5·GTP and 500 μm phospholipids but no PtdIns(3,4,5)P3. B, activity in the absence of lipids or detergents. PH1-Ank and ArfGAP-Ank were titrated into reactions containing [L8K]Arf5·GTP. The average ± S.E. from three experiments is presented.
