Kenneth Lindegaard Madsen's research group focuses on studying the reconstitution of membrane proteins into larger, organized protein scaffolds of key importance for neuronal signalling processes. The outcome of their research might to be a key in building synthetic biological systems of scaffolded membrane protein complexes.

Our research includes studies on PDZ domain mediated neuronal scaffolding interactions and BAR (Bin/amphyphysin/Rvs) domain mediated protein-lipid interactions. Of particular interest is the PDZ domain protein PICK1 (protein interacting with C kinase 1), whose scaffolding capacities show great potential for building organized, synthetic biological systems containing proteins that are studied in other labs within the center. 

Figure: Illustration of the scaffolding protein PICK1 binding the C-terminal tail of the dopamine transporter (blue) via the PDZ domain (green). The crescent shaped BAR domain (turquoise) serves to shape the membrane into high curvature to facilitate vesicle budding.

The work has both provided novel important insights into the cellular function of PICK1 and led to the identification of the first small molecule inhibitor of the PICK1 PDZ domain. The compound represents a possible lead in future development of therapeutics against neuropathic pain and stroke and, thus, the study strongly corroborate the potential of targeting intracellular protein-protein interactions in CNS-related diseases.
