摘要
The present invention concerns methods and compositions for stably tethered structures of defined compositions, which may have multiple functionalities and/or binding specificities. Particular embodiments concern homodimers comprising monomers that contain a dimerization and docking domain attached to a precursor. The precursors may be virtually any molecule or structure, such as antibodies, antibody fragments, antibody analogs or mimetics, aptamers, binding peptides, fragments of binding proteins, known ligands for proteins or other molecules, enzymes, detectable labels or tags, therapeutic agents, toxins, pharmaceuticals, cytokines, interleukins, interferons, radioisotopes, proteins, peptides, peptide mimetics, polynucleotides, RNAi, oligosaccharides, natural or synthetic polymeric substances, nanoparticles, quantum dots, organic or inorganic compounds, etc. Other embodiments concern tetramers comprising a first and second homodimer, which may be identical or different. The disclosed methods and compositions provide a facile and general way to obtain homodimers, homotetramers and heterotetramers of virtually any functionality and/or binding specificity.
