Dr. Wolfgang Dubiel

Dr. Dubiel obtained his Ph.D. at the Institute of Biochemistry, Humboldt University Berlin in 1982. After postdoctoral work at the Humboldt University Berlin and at the Department of Biochemistry, University of Utah, Salt Lake City, USA, he returned to the Institute of Biochemistry, Humboldt University Berlin as a lecturer in 1993. In 1999, Dr. Dubielobtained an appointment as a Professor and became the Head of the Division of Molecular Biology, Department of General, Visceral, Vascular and Thoracic Surgery, Charité – Universitätsmedizin Berlin. In 2016, Dr. Dubiel was invited as a Visiting Professor at the School of Pharmaceutical Sciences, Xiamen University, inDr. Dieter A. Wolf’s laboratory.

Dr. Dubiel is a leading expert in the field of intracellular protein degradation by the ubiquitin proteasome system. Among his most important achievements is the discovery of the COP9 signalosome complex (CSN), a regulator of cullin-RING ubiquitin ligases (CRLs).Since 2000, his research is focused on the structural and functional characterization of the CSN in human cells as well as its utility as cancer drug target. A very recent achievement was the identification of the CSN as a master regulator of adipogenesis, the differentiation of fat cells (adipocytes). The CSN is involved in the re-modeling of the CRL network in adipocytes to switch to the differentiation mode. This makes the CSN an attractive target for the treatment of obesity and other metabolic diseases.

At Xiamen University, in Dr. Wolf’s lab, Dr. Dubiel will focus on the role of the CSN and of CSN variants in tumor cells and during adipogenesis. In collaboration with Dr. Wolf, he will screena new library of largely unexplored natural product resources of the South China Sea presently being developed in Dr. Zhang’s group. Using this library, he expects to identify novel modulators of adipogenic pathways that could provide proof-of-concept for targeting the CSN in metabolic disease.
