摘要 (Abstract)：

Intrinsically disordered proteins (IDPs) account for a significant fraction of any proteome and are central to numerous cellular functions. Yet how sequences of IDPs code for their conformational ensembles, conformational dynamics, and ultimately, functions is poorly understood. I will report our advances from GPU-accelerated molecular dynamics simulations. Three topics will be covered. (I) IDPs in solution. Results include force field selection [1], AI-based conformational mining [2], and characterization and prediction of sequence-dependent backbone dynamics [3, 4]. (II) IDP-membrane association. Results include characterization of fuzzy membrane association [5] and prediction of residue-specific membrane association propensities [6]. (III) Liquid-liquid phase separation. Results include calculations of thermodynamic and dynamic properties of biomolecular condensates [7, 8].
