In budding yeast, polarized Cdc42 localization is supported in part by guanine nucleotide dissociation inhibitor (GDI)-mediated extraction from the plasma membrane. Li and colleagues now show that a lipid flippase complex containing Lem3 and Dnf1 or Dnf2 contributes to membrane lipid asymmetry to facilitate GDI-mediated extraction of Cdc42.
