WebMay 6, 2024 · There are two major types of phospholipid scramblases. Caspase-dependent lipid scramblases such as Xkr8 induce PS externalization ( 24 ), which serves as an eat-me signal in apoptotic cells to attract phagocytes and to initiate phagocytosis ( 15 ). 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. how to say sales in spanish https://gallupmag.com
