However, the enzyme scramblase catalyzes the … WebApr 14, 2024 · Although CL resides on the IMM of healthy cells, proapoptotic stimuli and recognition of PAMPs induce phospholipid scramblase 3 (PLS3) to translocate CL to the outer mitochondrial membrane (OMM). Once exposed to the cytosol, CL can act as a platform for inflammasome activation by binding to NLRP3 and caspase-1 [60]. Although …
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.
