Mutations in PDZ Binding Motif (PBM)-containing proteins associated to the Usher syndrome
Nicolas Wolff (PI)
Mutations in PDZ Binding Motif (PBM)-containing proteins are also associated to the Usher syndrome, a genetic disease resulting in both hearing loss and visual impairment. Most Usher proteins are present in auditory hair cells […]
Rabies virus neuronal infection
Nicolas Wolff (PI)
We have shown that proteins from Rabies virus during infection disrupts the interactions of the kinase MAST2 and phosphatase PTPN4 (PDZ domain) with their respective PDZ Binding Motif (PBM)-containing cellular ligands, the phosphatase PTEN […]
Role of PDZ-binding motif from Flavivirus non-structural proteins in flaviviral life cycle
Nathalie Pardigon (PI)
Arthropod-borne viruses (arboviruses) include numerous human and animal pathogens that are important global health threats. Flaviviruses are arboviruses belonging to the Flaviviridae family. They include neurotropic viruses such as West Nile (WNV), Japanese encephalitis […]
I did my Master and my PhD in the NMR unit of Biomolecules headed by Mrs. Delepierre at the Institut Pasteur. My thesis focused on the study of heme acquisition mechanism in bacteria. I used biophysical approaches, mainly nuclear magnetic resonance (NMR). I joined for my post-doc the team of biocrystallography led by Stéphane Bressanelli in the Molecular and Structural Virology Unit directed by Yves Gaudin (Gif-sur-Yvette). My project focused on the study of genome replication of hepatitis C virus (HCV). I acquired a dual expertise in NMR and X-ray crystallography. Then I joined the team of Nicolas Wolff. I worked mainly on the human phosphatases PTPN4 and PTPN3. More generally, I am interested in the signaling pathways of the cell involving PDZ-containing proteins.
Our group joined the Channel Receptors Unit since 2018 led by Pierre-Jean Corringer (Department of Neuroscience). The Unit is interested by the pentameric ligand-gated ion channels (pLGICs). This superfamily of membrane proteins are involved in particular in the neuronal communication.
