Unraveling the role of aminoacyl-tRNA synthetases in the etiology of Charcot- Marie-Tooth neuropathies


We are an international team of researchers belonging to the Jordanova lab at the VIBUAntwerp Center for Molecular Neurology (, looking for an enthusiastic colleague who wants to perform his/her PhD study on unraveling the molecular mechanisms leading to Charcot-Marie-Tooth neuropathy, the most common genetic disorder of the peripheral nervous system.

Our pioneering studies demonstrated that aminoacyl-tRNA synthetases (aaRS) play a critical role in the degeneration of peripheral nerves. We identified that heterozygous mutations in the tyrosyl-tRNA synthetase (YARS) cause a subtype of CMT disease (Jordanova et al., Nat Genetics 2006). Together with 5 other tRNA synthetases, this family of enzymes represents the major protein cluster associated with CMT disease to date. Under normal circumstances, aaRS catalyze the charging of tRNAs with their cognate amino acids in the first step of protein biosynthesis. However, our findings demonstrated that lack of aminoacylation activity is not a prerequisite for disease to occur (Storkebaum et al, PNAS 2009). Rather, the CMT mutations lead to a gain of neurotoxic function and interfere with activities of these enzymes beyond protein translation. In a recent study, we established that YARS acts as a transcriptional regulator in the nucleus and the CMT-causing mutations impair this ex-translational function (Bervoets et al., Nature Communications 2019). Still, the exact mechanism leading to neurodegeneration remains elusive, and it is not clear whether it is shared between all CMTassociated synthetases. In the advertised project, the PhD student will combine genetic, transcriptomics, biochemical and cell biological approaches in Drosophila and cellular models, and iPSC-derived patient’s motoneurons, in order to gain insights into the intricate molecular mechanisms leading to aaRS-associated neurodegeneration.

The successful candidate will join an ongoing project and will be embedded in a multidisciplinary team of wet lab scientists and clinical experts. As part of the VIB-UAntwerp Center for Molecular Neurology ( and VIB (, the PhD student will benefit from established collaborations and access to centralized facilities with expertise in genomics, functional genomics and cell biology, proteomics, microscopy, structural biology, technology development, and bioinformatics. VIB provides a highly interactive environment and ample training opportunities for its researchers. In addition, the VIB-UAntwerp Center for Molecular Neurology is located in the city of Antwerp, the capital of Flanders, offering a culturally and historically rich, and ethnically diverse environment.


Predoctoral candidates are expected to have:

  • Master’s degree in molecular biology, cell biology, biochemistry or biomedicine awarded from a University in the European Economic Area, Switzerland or UK, and obtained no earlier than 2018;
  • Experience in working with Drosophila or with (iPSC) cell cultures would be an advantage;
  • Ability to extract and summarize data from the literature;
  • Ability to formulate research objectives and to design an experimental plan;
  • Ability to self-organize work and willingness to collaborate with others;
  • Passion for science, flexibility and team spirit;
  • Excellent verbal and written English communication skills.

How to apply?

Motivated candidates are asked to apply online. A complete application file should contain the following documents:

  • Detailed CV containing list of publications (if any)
  • One-page motivation letter including description of previous research experience and
  • research interests
  • Names and addresses of 2 referees
