Research focus

As proteins are among the main molecular players in cells, their in-depth study is important for cancer research as in cancers, proteins are frequently (de)regulated or mutated. My group has introduced and applied novel technologies for comprehensive analysis and quantification of cellular proteins; the proteomes. We focus our proteome studies on the analysis of several protein modifications such as protein phosphorylation by kinases, protein ubiquitination and protein processing by proteases. In addition, we are particularly interested in N-terminal proteoforms that result from different usage of translation initiation codons amongst others. We use high-end mass spectrometers for identifying proteins with deregulated levels among different proteomes, allowing us to spot potential protein biomarkers. Classical and novel affinity purification-mass spectrometry (AP-MS) approaches are used to map the composition of protein complexes in which most, if not all, proteins reside and exert their functions. We are particularly interested in protein biogenesis and combine ribo-seq data with positional proteomics data to map different N-terminal proteoforms and try to understand their functions. More recently, we implemented thermal proteome profiling proteomics for identifying the targets (and off-targets) of small molecule drugs and started clinical proteome studies in which we focus on disease-specific protein markers.
