Seminars at the Faculty of Informatics

Speaker: François-Xavier Theillet
  Université Paris-Saclay, France
Date: Wednesday, May 18, 2016
Place: USI Lugano Campus, room SI-003, Informatics building (Via G. Buffi 13)
Time: 14:30



NMR spectroscopy enables the detection of 15N/13C labelled species in cellular environments, and to monitor in real-time their conformational and chemical modifications. We will outline how this unique ability can be exploited in the fields of in-cell structural biology (1,2,3) and cell signaling by post-translational modifications (PTMs) (4,5,6).

François-Xavier Theillet obtained his PhD degree from the Pierre & Marie Curie University, Paris (2009). His project was a partnership between the university and the Pasteur Institut, supervised by Dr. Muriel Delepierre. Later, he was chosen for a postdoctoral fellowship at the Structural Biology Department of the Leibniz Institute for Molecular Pharmacology in Berlin, Germany (2010). Currently, he holds the position of first class researcher of CR1 class in the Biochemistry, Biophysics & Structural Biology Department of the Institute for Integrative Biology of the Cell (I2BC) in Gif-sur-Yvette, France (2015).

He is an expert in NMR techniques and, amongst his last projects, he studied new ways to detect cellular post-translational protein modifications of human p53.
