Research Interest
Localization of mRNAs and local protein synthesis contribute to asymmetric protein distribution, cell fate determination and neuronal function. Like translation or decay, mRNA localization is controlled by RNA-binding proteins (RBPs) or miRNAs. One aspect of our work is the functional characterization of known, novel, or unconventional RNA-binding proteins that act at organelle membranes, mainly using budding yeast as model. In mammalian cells, we study the composition of mRNA and protein complexes (mRNPs), using proximity labeling (BioID) as well as combinations of RNA live imaging and single-molecule FISH.


A second line of projects deals with the question how certain polyribosome-associated RBPs influence the translation of mRNAs and the function of the encoded proteins, especially in the case of aggregation-prone proteins like those found in polyQ-expansion related disorders. Using yeast as a tool, we study if and how these RBPs affect translation of specific transcripts, and how they influence folding of the proteins. We apply combinatorial approaches including imaging as well as low- and high-throughput protein analysis.
