Functional activity of proteins is tightly controlled via reversible post-translational modifications including phosphorylation, acetylation and ubiquitylation. These modifications enable the orchestration of cellular responses to a wide variety of stimuli. Due to these modifications, proteomes are overwhelmingly complex. Progress in the field has been greatly accelerated by the development of novel approaches to study these post-translational modifications at a proteome-wide scale using the sensitivity and robustness of mass spectrometry (MS). This has enabled the identification of thousands of dynamically regulated modification sites by MS. 

We are studying post-translational modification by the ubiquitin-like protein SUMO, predominantly found in nuclei of proliferating cells. SUMOylation is critical for eukaryotic life and regulates a wide variety of cellular processes including transcription, pre-mRNA splicing, translation, transport, replication and DNA repair. SUMO inhibition leads to loss of genome integrity and blocks cell cycle progression. Inhibitors of SUMO signal transduction are currently tested for their potential as novel anti-cancer agents. We are developing proteomics approaches to identify thousands of targets of this post-translational modification. Selected SUMO substrates are studied at the functional level to increase our understanding of the critical roles of SUMO in cell cycle progression and genome maintenance.
