[Regulation of vesicular transport by membrane curvature].

A cellular membrane is highly deformable: during the last decade, numerous studies have dissected at the molecular scale how during vesicular transport various proteins could deform a membrane or recognize membrane deformation. We will discuss how the activity of ArfGAP1 and GMAP-210, two proteins involved in vesicular transport, is regulated by membrane curvature thanks to an ALPS motif. Since a membrane is not solely defined by its shape but also by its lipids composition, we will show how others proteins are adapted to other lipid compositions to recognize membrane shape.
