Abstract
Recombinant proteins for siRNA delivery and a composition including same. These recombinant proteins include a p19 RNA binding protein and a target oriented peptide and can secure the stability of siRNAs from external attacks such as various degradation enzymes, have selective binding affinity to cancer cells by virtue of target-oriented peptides having various cancer cells as their target, and silence target genes by effectively delivering the siRNAs to cells and biological tissues by the release of the siRNAs to the cytoplasms after the cell penetration thereof. Therefore, they are expected to be effectively employed as siRNA delivery vehicles for siRNA therapeutic agents, cell-based drug screening compositions and research.
