Membrane Hydrodynamics and Their Role on Protein Interactions

Prof. Naomi Oppenheimer (Flatiron Institute, USA)

Since the 1970s vast research has been devoted to studying the equilibrium properties of membranes as elastic surfaces. Much less attention has been given to their in-plane dynamics, which is crucial for protein function. In this talk, I will describe the basics of membrane hydrodynamics and give a few implications of the results. From a coarse-grained perspective, the membrane could be considered as a quasi-two-dimensional (Q2D) colloidal suspension, where the lipids play the role of the molecular fluid, and the proteins play the role of particle inclusions. We will see a couple of implications of membrane hydrodynamics: (1) Hindrance of chemical reactions taking place in a membrane, (2) Fluid mediated self-assembly of ATP synthase proteins in a membrane, or of artificial rotating colloids in a soap film.

Last Highlight : Un projet LPTMS lauréat de l’appel 80|PRIME du CNRS

Dans le cadre des 80 ans du CNRS, la Mission pour les initiatives transverses et interdisciplinaires (MITI) a lancé l’appel à projet 80|Prime afin de soutenir et renforcer l’interdisciplinarité entre instituts. Le projet SaCyNet porté par Martin Lenz figure parmi les demandes financées. Il s'agit d'une collaboration avec le PMMH et le DC2P, portant sur les mécanismes d'autoassemblage des réseaux filamentaires qui confèrent leur forme et leur rigidité aux cellules vivantes.
