Cellular Logistics - 'Traceless' protein modification by small high-affinity tags in living cells

Labeling and modification of intracellular proteins remain a major challenge in life sciences, often limited by large fusion domains, high quantities of costly probes, and long reaction times. Here, we will guide protein trans-splicing by minimal high-affinity interaction pairs to trace proteins´ function and assembly in living cells. In addition, we aim at modulating cellular processes by light with high resolution in time and space. Combined with super-resolution microscopy and single-molecule analysis, these traceless approaches shall provide valuable insights into the co-operative function and suprastructures of proteins in particular at intracellular membranes.
