Molecular Machines Group

Group Leader: Dr Till Böcking



Overview of Research


We aim to elucidate the mechanisms of molecular machines in cellular assembly and disassembly processes. One of our research interests is focused on understanding how ATP-driven molecular chaperones mediate the disassembly of macromolecular complexes (Nat Struct Mol Biol 2011) and the restructuring of protein oligomers and aggregates in neurodegenerative diseases. Another project is aimed at elucidating the assembly pathways of specialised actin filaments decorated with actin-binding proteins.

To understand these processes we use a combination of biochemical and biophysical approaches. In particular, we develop fluorescence imaging approaches to visualise their dynamics at the single-molecule level. Our work also draws on approaches from the physical sciences including surface chemistry, microfluidics and automated image analysis.

More information on our current projects and news are available on our group website.
