WebMay 10, 2013 · Thus, a phospholipid scramblase that bidirectionally and nonspecifically transports phospholipids in response to Ca2+has been proposed (15). Using a liposome reconstitution system with synthetic phospholipids, Basse et al.(16) purified a 37-kDa protein from human erythrocytes and named it phospholipid scramblase (PLSCR). WebPhospholipid scramblases are required in the ER to promote uniform expansion of both leaflets of the bilayer after synthesis of phospholipids on the cytoplasmic side. Specific glycolipid scramblases are also required in the ER, where they play key roles in the assembly of lipid precursors needed for the biosynthesis of glycoproteins.
