Host: Prof. Rolf Jessberger (Institute of Physiological Chemistry)

The generation of messenger RNAs (mRNAs) and their translation into proteins depends on the elaborate interplay of a numerous trans-acting factors. These factors are often organized in macromolecular machines, which enable all steps in mRNA metabolism and timely coordinate their progression. The Fischer group studies the functional dynamics of key macromolecular machines acting on RNA using a combination of biochemical, structural and systems biology approaches. RNA-related pathways have been linked to a broad spectrum of human diseases. By combining basic RNA research with biomedical approaches we investigate how these pathways and networks are changed in different disease settings.
