Lipid scrambling in asymmetric plasma membrane models markedly enhances membrane undulations, driven by anti-registered lipid domains that couple leaflet curvature via preferred-curvature mismatch.
- Why it matters: The molecular mechanism linking lipid scrambling to large-scale plasma membrane remodeling is unclear, partly because domain reorganization during scrambling is not well resolved.
- What they did: Coarse-grained molecular dynamics simulations compared asymmetric versus fully scrambled plasma membrane models, analyzing how domain anti-registration and scrambling-induced domain enlargement affect curvature.
- The result: Long-chain sphingomyelin compositions stabilize anti-registered domains and associated curvature, and the scrambled model’s interleaflet domain organization shifts with system size from anti-registration to registration.
