Recombinant FGD2 directly binds to phospholipids. His-thioredoxin
protein alone (TRX; left) or His-thioredoxin-FGD2 fusion
protein (TRX-FGD2; right) was incubated with membranes
spotted with listed concentrations of phospholipids. After washing, bound
protein was detected with an anti-His antibody and chemiluminescence.
