Outline of Final Research Achievements |
In eukaryotic cells, Rab family small GTPases present the identity of each membrane fractions. Rab forms a complex with RabGDI in cytosol, and when necessary, appropriate Rab needs to be detached from RabGDI and inserted into the membrane. In this study, we have tried to reconstruct the Rab insertion system on the artificial membrane. Yip family transmembrane proteins and RabGEFs are proposed to function in the Rab insertion system. We have successfully prepared these components, which is necessary for the reconstruction of the Rab insertion system.
