This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the transport of phospholipids (Potential). Leads to neomycin-resistance when overexpressed. Required for traffic between late Golgi and early endosomes. ATP + H2O + phospholipidSide 1 = ADP + phosphate + phospholipidSide 2. Interacts with MON2. Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IV subfamily.
