Maria Gockert

During her PhD studies, Maria Gockert investigated the immediate function of the human RNA exosome and its associated nucleoplasmic adaptor complexes. Exosome mediated decay is central to numerous RNA processing and degradation events and therefore essential for cell homeostasis. Until now, functional analysis of these decay factors has been limited to long-term depletion experiments, that potentially fail to characterize direct protein function due to the emergence of secondary effects. To overcome this limitation, Maria has implemented a more rapid depletion method, the auxin inducible degron system. This system allowed the removal of the factors of interest within a short experimental time window and thereby enabled the delineation of RNA targeting events as well as the identification of indirect effects. The new research findings help further our understanding of the intricate dynamic mechanisms underlying nuclear RNA decay.

The PhD study was completed at the Department of Molecular Biology and Genetics, Faculty of Natural Sciences, Aarhus University.

This summary was prepared by the PhD student.
