PEPTIDES FOR FACILITATING COMPOSITE RECEPTOR EXPRESSION AND TRANSLOCATION OF MACROMOLECULES

摘要

The invention relates to compositions and methods for expressing a composite receptor on the cell surface. The composite receptor can be integrated into a cell membrane via a fusion peptide which includes a cell penetrating domain linked to a transmembrane domain. In a preferred embodiment, the composite receptor further comprises a ligand binding domain. In yet another embodiment the invention relates to compositions and methods for translocating a nucleic acid or other molecule across the cell membrane into the cell. In a preferred embodiment, the nucleic acid or other molecule is linked to a fusion peptide comprising an adapter domain which is linked to a cell penetrating domain.
