Join us for the 2nd International Symposium on “Dynamic Organization of Cellular Protein Machineries” in Freiburg!
The goal of the SFB 1381 is to better understand how protein machineries are assembled during biogenesis, how they are organized in modular (sub-)assemblies and how the dynamics in assembly and organization and their regulation are used for precise operation of cellular functions.
Over the course of three days, we will explore these topics through presentations and discussions highlighting the latest research in the field. Invited speakers and SFB 1381 researchers from Freiburg will share their insights, and early career researchers are especially encouraged to present their work during the poster session.
