    Abstract:
    The description of the molecular mechanisms of interaction between tubulin or microtubules and partners at atomic scale is expected to have critical impacts on the understanding of basic physiological processes. This information will also help the design of future drug candidates that may be used to fight various pathologies such as cancer or neurological diseases. For these reasons, this aspect of tubulin research has been tackled since the seventies using many different methods and at different scales. NMR appears as a unique approach to provide, with atomic resolution, the solution structure and dynamical properties of tubulin/microtubule partners in free and bound states. Though tubulin is not directly amenable to solution NMR, the NMR ligand-based experiments allow one to obtain valuable data on the molecular mechanisms that sustain structure-function relationship, in particular atomic details on the partner binding site. We will first describe herein some basic principles of solution NMR spectroscopy that should not be missed for a comprehensive reading of NMR reports. A series of results will then be presented to illustrate the wealth and variety of NMR experiments and how this approach enlightens tubulin/microtubules interaction with partners.
