摘要
The assembly-disassembly cycle of COPI and COPII coats is controlled by the GTPase cycle of the small G proteins Arf1 and Sar. We describe here two spectroscopic assays that enable real-time studies of some elementary steps of coat assembly and disassembly on artificial liposomes of defined composition and curvature. A flotation assay to assess the effect of membrane curvature on protein adsorption to liposomes is also presented.
