Probable phospholipid-transporting ATPase IM (ATP8B4)

Part of a P4-ATPase flippase complex which catalyzes the hydrolysis of ATP coupled to the transport of aminophospholipids in the outer to the inner leaflet of different membranes and ensures the maintenance of asymmetric distribution of phospholipids. Phospholipid translocation appears also to be implicated in vesicle formation and in uptake of lipid signaling molecules (Probable).
