To date, more than 150 natural RNA modifications have been identified. However, the function and interplay among RNA modifications remains enigmatic.
The Vilardo lab investigates RNA modifications in tRNAs, the key adaptor molecules between gene expression and protein translation. We use biochemistry, genome editing by Crispr/Cas9, and Next Generation Sequencing to investigate tRNA modifications and the enzymatic pathways responsible for modifications.
As part of the special research focus program RNA-Deco, we collaborate within a network of top RNA research laboratories across Austria.

Open PhD Position - Jantsch Lab • open since January 25 2021

PhD position on RNA modifications and innate immune sensing

Michael Jantsch
Medical University of Vienna
Center for Anatomy & Cell Biology
Schwarzpanierstrasse 17
1090 Vienna

An EU-funded Ph.D. position is available in the lab of Michael Jantsch. The international training network (ITN) consists of a multinational team studying RNA modifications in a multidisciplinary approach. Secondments allow diverse training and research experiences at a competitive salary including family allowance.
The lab of Michael Jantsch studies adenosine deamination in mice which is one of the most abundant RNA modifications in mammals. Deamination of adenosines (A) leads to the formation of inosines (I). Inosines are interpreted as guanosines by most cellular machineries, including translation.
A to I editing is mediated by two enzymes, ADAR1 or ADAR2. While ADAR2 is mainly responsible for editing events that alter the coding of mRNAs or the function of small RNAs, ADAR1 acts as an antiviral protein. Interestingly, loss of ADAR1 leads to elevated interferon signaling and upregulation of the antiviral signals.
It will be the aim of this Ph.D. project to decipher the signals that trigger antiviral responses and to determine how the introduction of inosines prevents antiviral signaling (Fig 1).
Figure 1: Sensing of dsRNA by antiviral immune proteins. In the absence of A to I editing, dsRNA activates antiviral signaling by recruiting and activating the MDA5-MAVS signaling pathways. In the presence of inosines this pathway is suppressed. Currently, the underlying mechanisms are not well understood.

The Division of Cell & Developmental Biology provides a stimulating atmosphere for RNA research with five research groups working on RNA modifications. The team is tightly linked to other Austrian RNA researchers via an RNA research network. The Division of Cell & Developmental Biology is located near the center of historic Vienna.

Understanding the consequences of RNA-editing at the structural level

The labs of Kristina Djinovic-Carugo and Michael Jantsch are teaming up to understand how RNA-editing induced recoding of the pre-mRNA encoding the actin crosslinking protein filamin A changes the structure of this protein. To achieve this, the protein structure of parts of the filamin A protein will be determined in their natural and “edited” state.

Background: Adenosine deaminases acting on RNA deaminate adenosines to inosines in structured regions of RNAs. The RNA-editing process occurs in millions of sites in the human transcriptome. As inosines are interpreted as guanosines during translation, this RNA-editing process can alter codons and therefore lead to the formation of proteins that are not encoded in the genome. A prominent adenosine to inosine deamination event is found in the mRNA encoding filamin A, an abundant actin crosslinking protein that links the cellular cortex and transmembrane proteins with the cytoskeleton. Changes in the editing pattern of the filamin A mRNA lead to the expression of altered filamin A which causes high blood pressure but also causes gastrointestinal inflammatory disorders. To understand the molecular consequences of the editing-induced amino acid exchange, the affected domain will be studied by structural and biophysical means.

Thesis description: We are looking for a highly motivated and dedicated student to use a combination of structural and molecular biophysics approaches to investigate the molecular consequences of RNA-editing of filamin A. The successful candidate will have the opportunity to (i) express and purify native and “edited” variants and perform a comparative molecular biophysics analysis (ii) X-ray crystallography to determine their structures at high resolution (iii) use biochemical and biophysical methods to validate the mechanistic model.

Requirements: background in biochemistry or molecular biology, studies of Molecular Biology, Biochemistry, Chemistry, Cell Biology or related fields.
