Among Prof Sudol’s most significant achievements to date are the identification of a modular protein domain, known as the WW domain, and the characterization of its cognate ligands. In 2004, together with a research team at AxCell-Cytogen company, Marius Sudol reported the first comprehensive protein interaction map for a human modular domain. Today, the WW domain is known to mediate critical signals in tumor suppressor networks, including the Hippo signaling pathway. More importantly, syndromes such as the Golabi-Ito-Hall syndrome of intellectual disability and Liddle syndrome of hypertension are caused by loss-of-function point mutations in the WW domain or its cognate ligands.

The research conducted in Marius Sudol’s laboratory and those of his collaborators over the past two decades has directly contributed to a systems biology level understanding of signaling networks from the perspective of modular protein domains. As a co-founder and co-leader of the Protein Modules Consortium, he advocates systems biology approaches and synthetic biology strategies in designing therapeutic interventions based on the knowledge of the structure and function of protein modules.

Over the course of his scientific career spanning more than three decades, Marius Sudol has authored 130 publications, including original research articles and invited reviews in refereed journals as well as numerous book chapters. His current work focuses on the role of WW domain-containing proteins in the Hippo tumor suppressor network and Golabi-Ito-Hall syndrome of intellectual disability.
