Abstract / short description:
This project takes a physical approach to investigate intrinsically disordered proteins (IDPs) in aqueous solutions. Novel X-ray and neutron scattering methods and coarse-grained modeling have been established as suitable techniques to explore IDPs, but systematic studies are still missing to combine these methods into a general, comprehensive description of IDPs.
Therefore, the objectives of this project are to use scattering techniques combined with modeling and simulations
(1) to characterize the conformations sampled by model IDPs under different well-controlled conditions,
(2) to analyze how these conformations depend on the chemical properties of the IDPs, and
(3) to understand how and why small differences in chemical properties and conformations lead
to large differences in self-assembly pathways for IDPs.
To this effect, robust, representative model IDP systems will be employed and be compared to natively folded protein reference systems.
These objectives shall help to contribute to answer the central guiding question of the project:
How does disorder of proteins affect their assembly and the associated dynamics from the amino acid level up to the length scale of protein assemblies?
The central guiding question will be addressed by a series of more fundamental questions that will each give rise to a work package (WP) in this project.
The answers to these questions shall help to test the central hypothesis that differences in protein disorder govern the behavior on all length scales from the segmental dynamics to the macroscopic aggregation and phase behavior.
