| Outline of Final Research Achievements |
We tried developing a protocol to reconstitute GPCRs and following other elements of cell signal transduction pathways on artificial lipid membrane vesicles such as giant liposomes for realizing microscopic observation on function of the pathway with individual GUVs. We used our method to prepare giant proteo-liposomes through membrane fusion between GUVs and envelopes of recombinant baculovirus budded virus particles, and demonstrated GUVs containing recombinant receptors, effectors, or some proteins following these in actual cells, by microscopic observation. It is now difficult to construct the full pathway; however, we have obtained results about the availability of GUVs formed with a droplet-transfer method and characterization of budded viruses prepared using some culture procedures, which give useful information to improve our study on reconstitution of membrane protein systems on giant proteoliposomes.
