Recombinant protein platform for high-throughput investigation of peptide-liposome interactions via fluorescence anisotropy depolarization

Antonis Margaritakis, Meirui Qian, David H. Johnson, Wade F. Zeno, Tobias S. Ulmer, Peter J. Chung

This paper introduces a recombinant protein platform to measure binding affinity of inducible amphipathic helices to membranes using fluorescence anisotropy.

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.
