Membrane Phase, Charge, and Curvature Regulate α-Synuclein Binding Dynamics

Orianna H. Kou, Cailyn M. Sakurai, Stephanie Y. Ramirez, B J Kim, D L Johnson, Zixin Zhang, Christopher T. Lee, Wade F. Zeno

This study investigates how membrane phase, charge, and curvature jointly regulate α-synuclein binding dynamics using experimental and simulation methods.

Lipid Packing Defects are Necessary and Sufficient for Membrane Binding of alpha-Synuclein

David H. Johnson, Orianna H. Kou, John M. White, Stephanie Y. Ramirez, Antonis Margaritakis, Peter J. Chung, Vance W. Jaeger, Wade F. Zeno

This study shows that N-terminal acetylation of alpha-synuclein reduces its dependence on anionic lipids for membrane binding, demonstrating that membrane packing defects alone can drive binding.
