This invention is about a novel Biomolecule Transducton Motif (BTM), Sim-2 peptide, which has a potential to transduce many biological response modifiers effectively into the cytoplasm, intracellular organelles or nucleus of prokaryotic or eukaryotic cells in vivo and in vitro, and the related technological methods using Sim-2 BTM. This Sim-2 BTM can be used for Drug Delivery System, development of new recombinant protein vaccines or DNA/RNA vaccines, gene and protein therapy, production of pharmacologically or medicinally useful proteins or pharmacomedicinal drug therapy.
