Abstract

The objective of this paper is to investigate the structural stability, dynamic properties, and potential interactions among Amyloid Precursor Protein (APP), Tau, and Alpha-synuclein through a series of molecular dynamics simulations that integrate publicly available structural data, detailed force-field parameters, and comprehensive analytical protocols. By focusing on these three proteins, which are each implicated in various neurodegenerative disorders, the study aims to elucidate how their conformational changes and interprotein contact sites may influence larger biological processes. Through rigorous evaluation of their folding behaviors, energetic interactions, and residue-specific functions, this work contributes to the broader understanding of protein aggregation mechanisms and offers insights that may ultimately guide therapeutic intervention strategies.
