POLYSUMOYLATION-MEDIATED RELOCALISATION OF PROTEINS TO THE NUCLEUS

Protein modification with the small ubiquitin-related modifier (SUMO) is an essential reversible regulatory mechanism in eukaryotic cells known to cross-talk to other PTMs such as ubiquitylation, phosphorylation, and acetylation. Fluorescent reporter proteins fused to SUMO chains are strongly enriched in the cell nucleus. The goal of this project is to elucidate the mechanism of polysumoylation-mediated nuclear translocation and to investigate its reversibility.
