In this study, we constructed fluorescently labelled protein carrier constructed from cell-penetrating peptide (CPP) and RNA binding domain (RBD) for intracellular shRNA or siRNA delivery. The protein carrier specifically bound to an RNA cargo containing short extended sequence tag for protein binding, and internalized into CHO cells together with the RNA. Although the internalized protein/RNA complexes showed cytoplasmic punctuate distributions, they widely spread into cytosol by photo irradiation. Moreover, redistributed RNA induced gene silencing only within the photo irradiated area.
