Limited exposure of aminophospholipids on the outer leaflet of the plasma membrane is a fundamental feature of eukaryotic cells and is maintained by the action of inward-directed P-type ATPases ("flippases"). Yeast S. cerevisiae has five flippases (Dnf1, Dnf2, Dnf3, Drs2, and Neo1), but their regulation is poorly understood. Two paralogous plasma membrane-associated protein kinases, Pkh1 and Pkh2 (orthologs of mammalian PDK1), are required for viability of S. cerevisiae cells because they… CONTINUE READING
