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

The plasma membrane contains a broad range of lipids making up the bilayer. Aminophospholipids (APLs) 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).

质膜内含有多种脂质，构成了双层结构。氨基酸磷酸脂（APLs），例如磷脂酰丝氨酸（PS）和磷脂酰乙醇胺（PE），均匀分布在双分子层中，其排列由P型ATP酶IV家族（Paulusma and Oude Elferink, 2005）介导。
