Institute of Biochemistry and Biophysics PAS, Genetic Department announces recruitment for the post-doc position for the realization of the OPUS project of National Science Center of Poland untitled:

" Regulation of cell death and OXPHOS activity by Fmp40 ampylase in yeast S. cerevisiae "

Project director: dr hab. Róża Kucharczyk

Project description:

Project aims to decipher the role of newly discovered yeast ampylase Fmp40p, the only identified ampylase in yeast. This protein is involved in cell response to reactive oxygen species, ROS. The preliminary data indicate that it can be involved in regulation of OXPHOS activity, the mitochondrial permeability transition and the programmed cell death pathway trough ampylation of proteins being a direct line of defense against ROS: glutaredoxins, thioredoxins or peroxiredoxins. The results of research will be significant not only for fundamental science but also mecine, as ROS signaling is involved in many diseases in humans, including cancer.

In the frame of this project we plan following experiments aiming to define the mechanism of action of yeast SelO (Fmp40p): 1) determination  of the  AMPylation by  Fmp40  of  potential substrates in  vivo and in vitro: subunits of ATP synthase, complex IV, peroxiredoxin and porin components; 2) studies  on the  PCD  in fmp40Δ cells and  the  role  of  Fmp40p  in PCD induction by oxidized thioredoxin Trx3, which role in PCD is documented in the literature; 3) study of the permeability transition pore function in yeast dependently on ampylation of its components (ATP synthase) or modulators (porin complex). Independently,  thanks’  to our expertise  in  the  modification  of  mitochondrial  genome  in  yeast, one of the task aim to construct  a  reporter  strain  expressing  the  non-fluorescent  part  of  GFP (first  10  of  11  GFP β-strands)  from  mitochondrial  genome  and  localize  it in  the  intermembrane  space  of  mitochondria. Such  a  GFP  protein  become  fluorescent  only  when assembled  with  the  11-th β-strand  of  GFP provided by any protein localized in the intermembrane space of mitochondria. This tool will be commonly used not only by yeast community.

The methods include: 

- expression of potential substrate in bacteria for ampylation reaction in vitro, ampylation verification in vivo,

- construction of the mutants, their genetic and phenotypic analysis

- on isolated mitochondria: measurement of oxygen consumption, ATP synthesis and hydrolysis, stability of inner membrane potential, ATP-driven translocation of protons across mitochondrial inner membrane, assembly and stability of ATP synthase, measurement of mitochondrial swelling and calcium retention capacity informative about induction of permeability transition pore.

- introduction of DNA bearing GFPβ1-10 into mitochondria of yeast by biolistic transformation and integration of this gene into mitochondrial genome.

Requirements

- Master degree in biology, medicine, pharmacy, or related fields in biochemistry or life science

- knowledge of microbiology (culturing of yeast), molecular biology methods (mutagenesis in vitro, plasmid construction, work with proteins, protein expression in bacteria, in biochemical methods (in mitochondrial biochemistry). Experience in any of these areas will be an asset.

- Passionate about scientific, sometimes hard work, highly motivated

- Creative and an analytical thinker, initiative in experimental design

- Ability to communicate fluently in English
