AUFGABEN-Beschreibung

 

The nuclear pore complex (NPC) is a large cylindrical structure of over 30 different proteins named nucleoporins (NUPs) that is embedded in the nuclear envelope. It facilitates the essential process of nuclear-cytoplasmic transport of RNA molecules and proteins. 

 

NPCs assemble in the intact nuclear envelope by an inside-out mechanism. How this process works, is modulated during aging and changed in cancer cells is largely unknown and will be studied in this project. We have developed a fast and highly efficient CRISPR approach for gene tagging. With this in hand, we will tag endogenous NUPs with fluorophores such as NeonGreen and degron tags and study their behaviour, function and biogenesis in different cell lines and under various growth conditions.

The PhD student will use biochemical approaches, conventional light and super resolution microscopy (STED; SIM)and electron microscopyfor the analysis of the NPCs. CRISPR technology will be used for genomic tagging of human NUPs.
