Highly qualified and motivated individuals are invited to send applications for a Postdoc Position in the Research Group of Wolf B. Frommer on the topic

Regulatory circuits controlling sugar flux in yeast grown on ethanol

HT screen of the yeast knock out collection using FRET sensors for glucose, sucrose and maltose, follow-up analysis of hits and reconstruction of networks

Our lab has developed a wide range of FRET sensors for metabolites. These sensors have so far been used mainly in mammalian cells to study glutamate release from neurons, glucose transport across the ER membrane or tryptophan/kynurenine exchange.

We have now been able to functionally express the FRET sensors also in the cytoplasm of yeast and to establish a high throughput screening platform. Our goal is to identify novel regulatory pathways involved in the control of glucose flux in yeast. As a first step, the kinase k.o. collection has been screened for altered glucose flux and several hits have been identified and verified.

Next steps will be to verify the hits using a new microfluidic platform, to test the effect on other sugar fluxes using FRET sensors for sucrose, maltose and ribose and to place the kinases into signaling networks. The screen can be expanded to include the whole genome at a later stage. Focus points are regulatory effects on glucose transporters and hexokinases. Due to the advanced stage, it is expected that the work will lead to high profile publications within less than a year.
