Folding and misfolding on the ribosome – Nascent chains interactions
Our main research objective is to resolve the long-standing question: How do cells direct their proteome to fold to their native, functional state and avoid misfolding diseases?
We are studying the role of the ribosome as a platform for coordinating complex assembly during synthesis, by advanced techniques combining biochemistry and deep sequencing such as selective ribosome profiling as well as super-resolution microscopy. We are also developing tools for studying single-molecule mRNA-protein interactions, in vivo. We are exploring the mechanisms guiding the folding and assembly of newly synthesized proteins into multi-molecular complexes as well as the mechanisms for degradation of “lonely” subunits.

During the summer we invite you to participate in one of the following projects:

  • Evolution of protein folding and assembly pathways.
  • Mechanistic analysis of an innate immune response called ISGylation at the ribosome following viral infections.
  • Developing a single-molecule approach to ribosome profiling, based on the nanopore sequencing platform.
  • Discovery of assembly-specific degradation factors; a systematic, proteome-wide identification of novel, co-translationally acting degradation factors.
  • Study of mRNA spatial organization in the cell utilizing single molecule super-resolution imaging approaches.
  • Computational modeling of co-translational interface folding.
