Subgoal 1
Subgoal A is construction of liposome that penetrate through human cell membranes.
To acheive this, we designed liposomes with HIV-1 TAT peptide.
HIV-1 TAT is a Protein Transduction Domain(PTD). Liposomes made of peptidolipid with HIVｰ1 TAT is known to penetrate through cell membrane. It is suggested that HIV-1 TAT promotes endocytosis,though the precise mechanism remains unclear.
Then we fused HIV-1 TAT with potential anchor protein (LALAAAALALAAAALALAAAA). The LALAAAA side of this fusion protein is expected to be anchored in the lipid barrier of liposome. And the TAT side of the protein will be exposed to water so that TAT domain can touches the cell membrane. When exposed to cells, liposomes with this fusion protein will promote endocytosis and be taken into the cell.
We constructed plasmids encoding this fusion protein. When this plasmid is mixed with mixture of liposomes and cell-free protein synthesis system, the fusion proteins will be synthesized and anchored on Liposomes.
