Brief summary of research over the last five years
My group has made important contributions in the nuclear transport field studying the mechanism of transport of membrane proteins. Specifically, we discovered that, while the majority of membrane proteins simply reach the inner membrane by diffusion, a selective and energy-dependent transport mechanism exists for two yeast proteins, and likely for a third human protein. Intriguingly, these three proteins all act in nuclear pore complex (NPC) assembly and quality control, which led me to question whether this special transport mechanism may be important for NPC quality control.
In collaboration with others, my team developed new methods and generated a first system-wide inventory of the molecular changes in mitotic ageing yeast. We found that a major signature of ageing cells is an altered stoichiometry in protein complexes, which was particularly strong for the NPC.
To then answer the many unresolved questions with regard to the function of the NPCs in ageing cells, we follow nuclear transport in ageing yeast cells. Using microfluidic devices, we monitor cells over their entire life span under perfectly controlled environmental conditions. My team found that NPC quality control is compromised in ageing cells, and associated with reduced transport across the nuclear envelope.
Altogether, my research lines—related to the function of the NPC, on the one hand, and to understanding what cellular ageing is on a molecular level, on the other—have now converged and jointly point to the importance of NPC quality control.
