Phd Fellowship In Bioinformatics

Reference : PhD Gilles Travé

Publication de l'offre : 10 octobre 2016

The Department of Integrative Structural Biology, of the Institut de Biologie Moléculaire et Cellulaire (IGBMC-CERBM), University of Strasbourg, is pleased to announce that a three-year PhD fellowship will be available from 1 February 2017 or as soon as possible thereafter. The application deadline is 30 November 2016.

 

Applications are invited from applicants who hold or expect to hold a master´s degree in bioinformatics, to perform the following PhD project: Hijacking of human PDZ domains by viral proteins.

 

Missions

Project description

Many protein-protein interactions are mediated by "domain-motif interactomes", i.e. networks of globular domains binding to short linear amino-acid sequence motifs, in complex intracellular competitions that depend on individual binding affinities. Pathogens such as viruses have developed strategies to "hijack" particular cellular functions by interfering with host domain-motif interactomes involved in these functions. A prototypical example is given by the interference of viral proteins with human PDZ domains. PDZ domains are a family of globular domains that recognize short linear motifs bearing a specific consensus sequence at the extreme C-terminus of their target proteins. The human proteome counts 266 PDZ domains dispersed over 152 proteins, and about 5000 putative PBMs (PDZ-binding motifs). PDZ-PBM interactions often participate in cell adhesion and polarity processes critical for cellular differentiation, proliferation and migration. Remarkably, many viral proteins contain PBMs that target PDZ-containing cellular proteins.

 

We are an experimental team interested in the human PDZ-PBM interactome and its hijacking by viral proteins. In an effort to address this topic in a quantitative manner, the team is developing methods that not only identify domain-motif interactions, but also evaluate their affinity constants. This allows comparing and ranking all interactions based on interaction strength, rather than just providing a binary information ("bind" or "does not bind"). The team has already published a chromatographic approach, called the "holdup assay" which allows measuring up to 1000 affinities per day (Vincentelli et al., Nature Method 2015). The team has also cloned and expressed a library containing the 266 human domains (the "PDZome") which can be used to measure the binding of any PBM of interest to the entire human PDZome.

 

In this project, we will further develop the holdup assay together with other approaches, to reach an increased throughput allowing to evaluate the affinities of at least 10.000 domain-motif interactions a day. This approach will be applied to ii) quantitatively map the entire human PDZ-PBM interactome by identifying all PDZ-PBM interactions and measuring all their binding affinity constants; ii) identify the interactions and the binding affinity constants of the human PDZome vs a panel of viral proteins known to contain C-terminal PBMs. In tight collaboration with experimentalists from the team, the candidate will use bioinformatics tools to design the experiments, treat the large-scale data, analyze the results in the context of pre-existing data from other groups, and set up a website allowing other researchers to visualize the results.

 

The PhD fellowship is part of the EU-funded project, PDZnet, which is an ambitious inter- and multidisciplinary European Training Network under the H2020 Marie Sk?odowska-Curie Actions (www.pdznet.eu) offering training for 14 PhD fellows. The PDZnet consortium contains 12 different partners in 6 EU countries (Denmark, Sweden, Germany, France, Italy, Portugal). The PDZnet training programme involves a range of network wide training activities.
