Using mass spectrometry to study protein interactions
All biological processes can be described as biomolecules “talking” to each other, providing cargo, information, or transportation. These events usually take the from of a direct physical contact, i.e. a non-covalent interaction, in which one molecule, most often a protein, binds to one or more partners, inducing a change in the three-dimensional structure. In this manner, proteins can keep in touch with their environment to control their function. For example, upon sensing a change in pH, sider silk proteins lock each other into infinite chains to form very stable scaffolds, and membrane proteins can recognise individual lipid molecules in their environment to tune their activity accordingly. Aberrant, -faulty- interactions, on the other hand, interfere with these processes and are therefore often associated with diseases. Disrupting the interactions between the tumour suppressor p53 and its targets leads loss of cell cycle control and impaired DNA damage repair, giving rise to cancer. Some proteins even interact with themselves and form toxic structures such as amyloid fibrils that eventually lead to degeneration of the affected tissue, as seen in e.g Alzheimer's disease. Therefore, it is important to understand how exactly proteins “talk” to each other, and use this information to find ways to prevent interactions from going wrong.
My research focuses on the use of mass spectrometry (MS), a technique which allows us to determine the exact weight of biomolecules, to study how proteins recognise and bind their partners. MS is well-suited for the study of transient interactions, large complexes and even instable proteins, all of which are refractory to other structural biology methods like NMR and X-ray crystallography. For this purpose, we combine several complementary approaches:
- In “native” MS, we gently transfer proteins together with their binding partners from physiological solutions into the vacuum inside the mass spectrometer and measure the weight and stability of the resulting complex. This reveals what type of interaction holds the partners together, and how many (and which) molecules are involved.
- Hydrogen/deuterium exchange MS measures the incorporation of a chemical label (Deuterium) into the protein. Deuterium is incorporated into flexible and exposed parts of the protein. By measuring the resulting increase in weight, we are able to determine the stability and folding state of a protein, and even locate binding sites for tother proteins.
- MS-based proteomics allows us to identify individual proteins from complex mixtures based on their unique mass “fingerprints”. Using individual proteins as bait, we are able to fish out their specific interaction partners and map upstream and downstream targets.
The combination of all three techniques provides direct insights into several aspects of an interaction, but also generates constraints that can be used to direct computational modelling. Currently, we are using our toolbox to better understand how cancer-related proteins change their structure in response to drug binding, as well as develop MS strategies to study proteins directly in their cellular environment.
We also collaborate with David Drew (Stockholm U) on membrane protein-lipid interactions, Erik Marklund (Uppsala) on integrating MS and MD simulations, Carol Robinson (Oxford) on MS method development, and Jan Johansson (KI) and Annar Rising (SLU) on protein aggregation and spider silk.
