  • Title: Protein transduction: an alternative to genetic intervention?
    Author: Ford KG, Souberbielle BE, Darling D, Farzaneh F.
    Journal: Gene Ther; 2001 Jan; 8(1):1-4. PubMed ID: 11402295.
    Abstract:
    Protein transduction, an emerging technology with potential applications in gene therapy, can best be described as the internalisation of proteins into the cell, from the external environment. This process relies on the inherent property of a small number of proteins and peptides of being able to penetrate the cell membrane. The transducing property of these molecules can be conferred upon proteins which are expressed as fusions with them and thus offers an alternative to gene therapy for the delivery of therapeutic proteins into target cells. This review describes the three most commonly used protein transduction vehicles; the antennapedia peptide, the herpes simplex virus VP22 protein and HIV TAT protein transduction domain. The future prospects for the application of this technology in gene therapy are also discussed.
