Major Research Interests

mRNA quality control:
Messenger RNAs are transcribed in the nucleus and translated in the cytoplasm. Thus, it has to be assured that intron containing pre messenger RNAs are retained in the nucleus until processing is completed. RNA quality control allows only fully processed and spliced mRNAs to be transported and translated. Defects lead to diseases such as cancer and neurodegenerative diseases. Our projects functionally study mRNA quality control.
ncRNA functions:
non coding (nc)RNAs make up more than half of all RNAs in cells. However, the knowledge about their cellular functions lack far behind the knowledge of coding mRNAs. In this project we are investigating the function of individual lncRNAs, e.g. those involved in cellular iron metabolism, important to understand iron-related diseases, or the telomerase, important for the unlimited growth of most cancer cells.
We use the eukaryotic model organism Saccharomyces cerevisiae that has proven to be pioneer organism for studying fundamental basic scientific questions.
