ERC Synergy Grant to unravel the formation of protein complexes

News - 26 October 2022 - Communication TNW

A prestigious ERC Synergy Grant worth 9.4 million euros has been awarded to the research groups of Prof. Sander Tans from research institute AMOLF, Prof. Bernd Bukau from Heidelberg University, and Prof. Nenad Ban from the ETH. The team aims to elucidate a new mechanism to explain how protein complexes are formed – the complex molecules that execute all main biological functions. Prof. Tans holds a professorship at Delft University of Technology.

Protein complexes are essential to all cellular processes, yet their formation is also an extremely sensitive process that is prone to failure. Indeed, protein misfolding and aggregation are thought to underpin most non-infectious diseases and ageing. Rapidly accumulating findings now suggest that multiple ribosomes actively work together to orchestrate when and where different proteins come together. The research team expects that this coordinated  process enables unprecedented protein production capabilities and indicates a wide spectrum of yet unknown regulatory mechanisms in cells. 

To elucidate how protein complexes are produced, the team will combine a range of cutting-edge methods: RNA deep sequencing approaches that allows one to map out ribosome interactions throughout the genome, single-molecule methods that provide a direct view on how the ribosomes move along the mRNA and proteins assemble into complexes, and (tomography) Cryo-EM that enables one to visualize the internal structures of the highly complex multi-ribosome assemblies within cells. 

This ambitious program aims to reveal mechanisms that impact a vast spectrum of protein complexes and to uncover unknown layers of control in protein biogenesis. These insights will be useful for diverse applications, such as the design of mRNA vaccines and therapies, and to provide new hypothesis for the causes of various medical conditions.
