Research in the Holub Laboratory of Chemical Biology focuses on developing chemical tools to study and manipulate protein-protein interactions. More specifically, our group uses interdisciplinary approaches to design synthetic biologics and pro-fluorescent ligands that can be used to target interfacial contacts between proteins. To facilitate these studies, members of the Holub Laboratory utilize a variety of different laboratory techniques including organic synthesis, solid-phase peptide synthesis, protein expression/purification and fluorescence-based screens. The overall goal of our research is to gain insight into the physicochemical properties that regulate contacts between proteins. This knowledge can be used to advance development of new therapeutic approaches for diseases including cancer, Alzheimer’s disease and acromegaly.

There are currently three main areas of active research in the Holub Laboratory:
