First, we confirm that the protein with the signal peptide for yeast can be taken in yeast’s mitochondria. Second, we make proteoliposome which has the recombinant of yeast TIM23 complex and mix it in Signal for TIM23 complex::GFP which is translated by RTS. Then we will observe the localization of EGFP fluorescence. | ||

Observation
Subgoal A
In the experiment on subgoal A, we are aimed to confirm that the liposome with HIV-TAT can intrude mammalian cells.We will mix pSB1A2-T7 promoter- HIV-TAT::(LALAAAA)3-ter and liposome with fluorochrome and translated by RTS. When HIV-TAT::(LALAAAA)3 is translated, it sticks the lipid bilayer. As a result, the liposome which has HIV-TAT on their surface is completed. Adding it to HeLa cells. Later, we will observe the fluorescence of liposome in HeLa cells.
