| Research Abstract |
The aim of this study is the development of an analytical method to observe the non-equilibrium dynamics of membrane proteins incorporated into model cell membrane. Giant vesicle (GV), which is closed bilayer lipid membrane with cellular size, was used as a reactor of model cell membrane for the cell-free synthesis of a fluorescent membrane protein, eGFP-BmOR1, and the spontaneous membrane insertion of eGFP-BmOR1 synthesized inside of GV was successfully observed. Upon the construction of a reflective interference contrast microscope, the non-equilibrium dynamics of GV settling on a glass substrate was revealed in a nanometer thickness resolution. The combination of these two technologies is expected to promote further progress in the analysis of the non-equilibrium dynamics of membrane proteins and lipid membrane.
