Research interests

Development of protein-protein docking algorithms (JPEG) The functions of most protein are subordinated to the interaction with one or more partners: small molecules, other proteins, nucleic acids, etc. Protein-protein complexes are involved in many cellular processes and consequently are of great interest for the biochemical and biological functionnal study of their components. As of today, while structural genomics projects increases dramatically the number of isolated protein structures, still very little is known on the multimolecular assemblies. More... .

Development of new algorithms for the detection of unfolded regions in protein sequences (JPEG) One condition required for the experimental resolution of a protein’s three dimensional structure is its ability to fold in a stable conformation. Many proteins consist in multiple structural domains separated by flexible regions. In this case, the experimental structural study of the complete protein is not possible. The individual domains have to be studied separately. However, there’s no available method to accurately detect the limits of these domains. Indeed, must of the available methods are based on sequence comparison. more

HalX: a LIMS for structural biology (JPEG) Data management has been identified as a crucial issue in all large scale experimental projects. In this type of project, many different persons manipulate multiple objects in different locations; thus, unless complete and accurate records are maintained, it is extremely difficult to understand exactly what has been done, when it was done, who did it, and what exact protocol was used. All of this information is essential for use in publications, for reusing successful protocols, for determining why a target has failed, and for validating and optimizing protocols. Although data management solutions have been in place for certain focused activities, for example genome sequencing and microarray experiments, they are just emerging for more widespread projects, such as structural genomics, metabolomics, and systems biology as a whole. The complexity of experimental procedures, and the diversity and high rate of development of protocols used in a single centre, or across various centres, have important consequences for the design of information management systems. Because procedures are carried out both by machines and by hand, the system must be capable of handling data entry both from robotic systems and by means of a user-friendly interface. The information management system needs to be flexible so that it can handle changes in existing protocols or newly added protocols. Because no commercial information management systems have had the needed features, most structural genomics groups have developed their own solutions. More

Rafale: methods for semi-automated function assignment (JPEG) Genome annotation consists in the characterization of the functions of genes and gene products and the biological proceses they participate in. This requires taking into account all the available information. Annotation thus requires integration of various, massive and herterogeneous data from four main sources:

  1. large scale experiments
  2. data stored in different repositories
  3. biological knowledge available in litterature
  4. data and results produced by in silico analysis techniques.

The objective of the Rafale project is to assist biologists in the complex task of integration by improving the interaction between the system and the human expert. As of today, the annotation process relies entirely on the expert who validates, confronts and integrates data and results produced by the system to give a coherent annotation. more
