Rezumat:

Many biological processes take place in close proximity to lipid membranes. For a detailed understanding of the underlying mechanisms, tools are needed for the quantitative characterization of such biomolecular interactions. In this work, we describe the development of methods addressing the dynamics and affinities of protein complexes attached to an artificial membrane system. A semisynthetic approach provides the Ras protein with palmitoyl anchors, which allow stable membrane insertion, as a paradigm for membrane associated proteins that interact with multiple effectors. An artificial membrane system is constituted by nanoparticles covered with a lipid bilayer. Such a stable suspension allows for the characterization of the interaction between membrane-bound Ras and effector proteins using conventional fluorescence-based methods.
