Abstract excerpt
Phospholipid flippases (P4-ATPases) translocate specific phospholipids from the exoplasmic to the cytoplasmic leaflet of membranes. While there is good evidence that the overall molecular structure of flippases is similar to that of P-type ATPase ion-pumps, the transport pathway for the "giant" lipid substrate has not been determined. ATP8A2 is a flippase with selectivity toward phosphatidylserine (PS),...
