UMR144 – Subcellular Structure and Cellular Dynamics

The mission of this unit is to understand the biogenesis of the cell compartments and the molecular mechanisms that govern normal cellular functions.

The main research themes of the unit include:

  • Transport pathways between compartments,
  • The dynamics of the actin- and microtubule-based cytoskeletons,
  • Three-dimensional structures of molecular motors,
  • Mechanisms of cell division and cell migration,
  • The mechanisms involved in establishing the polarity of epithelia and their differentiation,
  • Signalling pathways associated with tumour progression in several mouse models and human tumours,
  • Regulation of adhesive systems during morphogenesis and development.
