Phospholipid scramblase that transports phosphatidylserine (PS) and phosphatidylethalonamine (PE) bidirectionally from one leaflet to the other of the phospholipid bilayer to at least partially collapse the membrane asymmetry established by NEO1 and other flippases (PubMed:27811238, PubMed:28057802). Functions in the trafficking pathway from endosomes to the trans-Golgi network (TGN) (PubMed:28057802). Suppresses the growth defects caused by mutations of flippases including NEO1, DRS2, DNF1, DNF2 and DNF3, as well as of the DRS2 regulator CDC50. Present with 937 molecules/cell in log phase SD medium.
