S100A9 is a pro-inflammatory protein that co-aggregates with other proteins in amyloid fibril plaques. S100A9 can influence the aggregation kinetics and amyloid fibril structure of alpha-synuclein (?-syn), which is involved in Parkinson's disease. Currently, there are limited data regarding their cross-interaction and how it influences the aggregation process. In this work, we analyzed this interaction using solution 19F and 2D ^(15)N-¹H HSQC NMR spectroscopy and studied the aggregation...

Membrane Interactions of alpha-Synuclein Revealed by Multiscale Molecular Dynamics Simulations, Markov State Models, and NMR
?-Synuclein (?S) is a presynaptic protein that binds to cell membranes and is linked to Parkinson's disease (PD). Binding of ?S to membranes is a likely first step in the molecular pathophysiology of PD. The ?S molecule can adopt multiple conformations, being largely disordered in water, adopting a ?-sheet conformation when present in amyloid fibrils, and forming a dynamic multiplicity of ?-helical conformations when bound to lipid bilayers and related...

Abstract
Elucidating the structural details of proteins is highly valuable and important for the proper understanding of protein function. In the case of intrinsically disordered proteins (IDPs), however, obtaining the structural details is quite challenging, as the traditional...
