P-type ATPases type IV transport external-facing APLs to internal side of the plasma membrane

The plasma membrane contains a broad range of lipids making up the bilayer. Aminophospholipids such as phosphatidylserine (PS) and phosphatidylethanolamine (PE) are distributed in this bilayer and their arrangement is mediated by the P-type ATPases type IV family (Paulusma and Oude Elferink, 2005).

质膜富含多种脂质，构成了双分子层结构。氨基酸磷脂，如磷脂酰丝氨酸（PS）和磷脂酰乙醇胺（PE），均匀地分布于该双分子层中，其排列布局由P型ATP酶IV家族（Paulusma and Oude Elferink, 2005）介导。
