1. Protein Folding, Binding and Evolution : PDZ domains and paralemmins as model systems
Abstract : Proteins present at the synapse need to be multitasking in order to perform all vital functions in this limited space. In this thesis I have analyzed the function and evolution of such proteins, focusing on the PDZ domain and the paralemmin family. The PDZ domains bind to a wide variety of interaction partners.

2. Exploring the Role of the PDZ Domain in a Supramodule
Abstract : The postsynaptic density (PSD) is a large, dense and membraneless compartment of proteins associated below the postsynaptic membrane bilayer, and which constantly undergoes morphological alteration in response to synaptic activity. Formation of PSD is associated with liquid-liquid phase separation of scaffold proteins in complex with other PSD proteins. READ MORE

3. Shaking the EF-Hand. Dynamics and Ion-Binding to Calmodulin and Calbindin D9k
Abstract : The work described in this thesis represents a biophysical approach, mainly using nuclear magnetic resonance (NMR) spectroscopy, to investigate the impact of magnesium ions on the EF-hand calcium-binding proteins calmodulin and calbindin D9k, as well as the dynamics of these proteins at low calcium levels. The x-ray structure of magnesium-saturated calbindin D9k shows a magnesium ion in only one of the two ion binding sites. READ MORE

4. On protein structure, function and modularity from an evolutionary perspective
Abstract : We are compounded entities, given life by a complex molecular machinery. When studying these molecules we have to make sense of a diverse set of dynamical nanostructures with wast and intricate patterns of interactions. READ MORE

5. Deciphering conformational ensembles and communication pathways in biomolecules
Abstract : Life is constructed by small building blocks called cells. Proteins are the biomolecules within these cells which carry out different functions. Proteins located in the cell membrane, for example, allow for the transport of ions and small molecules, as well as communication, across the cell membrane. READ MORE
