Thomas Arnesen

Thomas Arnesen is a Professor and Group Leader at the Department of Biomedicine, University of Bergen, affiliated with the Faculty of Medicine. He leads the Translational Protein Research group (Arnesen Lab), focusing on protein N-terminal acetylation and its implications in cellular mechanisms and diseases.

His research interests span molecular biology, enzymology, and disease mechanisms, with emphasis on N-terminal acetyltransferases (NATs), protein modifications, cancer, genetic syndromes, and metabolic regulation. The lab investigates molecular mechanisms of acetylation, cellular impacts of NATs, and their roles in diseases like cancer and neurodegeneration.

Arnesen's publications predominantly explore protein modification machinery, enzyme kinetics, and disease links—especially in cancer, diabetes, and neurological disorders. His work often integrates structural biology, genetics, and proteomics to dissect acetylation pathways.

He oversees research supported by the European Research Council, Research Council of Norway, and other major grants. The Arnesen Lab employs biochemical, cellular, and genetic approaches, collaborating globally to advance understanding of protein acetylation in health and disease.
