Structural mass spectrometry techniques involve the analysis of protein assemblies at the molecular level to determine their three-dimensional structure and interactions. This research allows researchers to understand the organization and function of these complex protein complexes, which play a crucial role in various biological processes such as cell signaling, gene regulation and immune response.

Using structural mass spectrometry techniques, researchers can identify the components of protein assemblies, determine their spatial arrangement, and elucidate the dynamic changes that occur within these complexes. This information is essential for understanding how proteins work together to perform specific functions and how their dysfunction can lead to diseases such as cancer, neurodegenerative disorders and autoimmune diseases.

Furthermore, structural mass spectrometry techniques can also be used to study the interactions between proteins and other molecules, such as drugs or small molecules, providing valuable information for drug discovery and development. Understanding the binding sites and mechanisms of action of these molecules can help researchers design more effective and targeted therapies.

Furthermore, structural mass spectrometry techniques can be used to study post-translational modifications of proteins, such as phosphorylation or glycosylation, which play an important role in regulating protein function. By mapping these modifications on protein structures, researchers can gain insight into how they affect protein interactions and signaling pathways.
