Abstract
Antibody-drug conjugates, nanoparticles, and liposomes have been used for anticancer drug delivery. The success of targeted killing of cancer cells relies heavily on the selectivity of the drug delivery systems. In most systems, antibodies or their fragments were used as targeting ligands. In this study, we have investigated the potential for protein-based octomeric chemically self-assembled nanorings (CSANs) to be used for anticancer drug delivery. The CSANs are composed of a DHFR-DHFR fusion protein incorporating an EGFR-targeting fibronectin and the anticancer drug MMAE conjugated through a C-terminal farnesyl azide. The anti-EGFR-MMAE CSANs were shown to undergo rapid internalization and have potent cytotoxicity to cancer cells across a 9000-fold difference in EGFR expression. In addition, anti-EGFR-MMAE CSANs were shown to induce immunological cell death. Thus, multivalent and modular CSANs are a potential alternative anticancer drug delivery platform with the capability of targeting tumor cells with heterogeneous antigen expression while activating the anticancer immune response.

Abstract
The design of imaging agents with a high fluorine content is necessary for overcoming the challenges of low sensitivity in 19F magnetic resonance imaging (MRI)-based molecular imaging. Chemically self-assembled nanorings (CSANs) provide a strategy to increase the fluorine content through multivalent display. We previously reported an 19F NMR-based imaging tracer, in which case a CSAN-compatible epidermal growth factor receptor (EGFR)-targeting protein E1-dimeric dihydrofolate (E1-DD) was bioconjugated to a highly fluorinated peptide. Despite good 19F NMR performance in aqueous solutions, a limited signal was observed in cell-based 19F NMR using this monomeric construct, motivating further design. Here, we design several new E1-DD proteins bioconjugated to peptides of different fluorine contents. Flow cytometry analysis was used to assess the effect of variable fluorinated peptide sequences on the cellular binding characteristics. Structure-optimized protein, RTC-3, displayed an optimal spectral performance with high affinity and specificity for EGFR-overexpressing cells. To further improve the fluorine content, we next engineered monomeric RTC-3 into CSAN, η-RTC-3. With an approximate eightfold increase in the fluorine content, multivalent η-RTC-3 maintained high cellular specificity and optimal 19F NMR spectral behavior. Importantly, the first cell-based 19F NMR spectra of η-RTC-3 were obtained bound to EGFR-expressing A431 cells, showing a significant amplification in the signal. This new design illustrated the potential of multivalent fluorinated CSANs for future 19F MRI molecular imaging applications.

Abstract
Cancer stem-like cells (CSCs) are often the root cause of refractive relapse due to their inherent resistance to most therapies and ability to rapidly self-propagate. Recently, the antigen CD133 has been identified as a CSC marker on several cancer types and αCD133 therapies have shown selective targeting against CSCs with minimal off-target toxicity. Theoretically, by selectively eliminating CSCs, the sensitivity to bulk tumor-targeting therapies should be enhanced. Previously, our laboratory has developed bispecific chemically self-assembled nanorings (CSANs) that successfully induced T-cell eradication of EpCAM-positive (EpCAM+) tumors. We reasoned that targeting both CSCs [CD133-positive (CD133+)] and the bulk tumor (EpCAM+) simultaneously using our CSAN platform should produce a synergistic effect. We evaluated αCD133/αCD3 CSANs as both a single agent and in combination with αEpCAM/αCD3 CSANs to treat triple-negative breast cancer (TNBC) cells, which express a subpopulation of CD133+ cancer stem cells and EpCAM+ bulk tumor cells. Furthermore, an orthotopic breast cancer model validated the ability of αCD133 and αEpCAM targeting to combine synergistically in the elimination of TNBC MDA-MB-231 cells. Complete tumor eradication only occurred when EpCAM and CD133 were targeted simultaneously and lead to full remission in 80% of the test mice. Importantly, the depletion and enrichment of CD133 TNBCs highlighted the role of CD133+ cancer cells in regulating tumor growth and progression. Collectively, our results demonstrate that dual targeting with bispecific CSANs can be effective against heterogenous tumor cell populations and that elimination of primary and CD133+ CSCs may be necessary for eradication of at least a subset of TNBC.

Abstract
Inspired by the natural intercellular material-transfer process of trans-endocytosis or trogocytosis, we proposed that targeted farnesylated chemically self-assembled nanorings (f-CSANs) could serve as a biomimetic trogocytosis vehicle for engineering directional cargo transfer between cells, thus allowing cell-cell interactions to be monitored and facilitating cell-cell communications. The membranes of sender cells were stably modified by hydrophobic insertion with the targeted f-CSANs, which were efficiently transferred to receiver cells expressing the appropriate receptors by endocytosis. CSAN-assisted cell-cell cargo transfer (C4T) was demonstrated to be receptor specific and dependent on direct cell-cell interactions, the rate of receptor internalization, and the level of receptor expression. In addition, C4T was shown to facilitate cell-to-cell delivery of an apoptosis inducing drug, as wells as antisense oligonucleotides. Taken together, the C4T approach is a potentially versatile biomimetic trogocytosis platform that can be deployed as a macro-chemical biological tool for monitoring cell-cell interactions and engineering cell-cell communications.

Abstract
Few therapeutic options have been made available for treating central nervous system tumors, especially upon recurrence. Recurrent medulloblastoma is uniformly lethal with no approved therapies. Recent preclinical studies have shown promising results for eradicating various solid tumors by targeting the overexpressed immune checkpoint molecule, B7-H3. However, due to several therapy-related toxicities and reports of tumor escape, the full potential of targeting this pan-cancer antigen has yet to be realized. Here, we designed and characterized bispecific chemically self-assembling nanorings (CSANs) that target the T cell receptor, CD3ε, and tumor associated antigen, B7-H3, derived from the humanized 8H9 single chain variable fragment. We show that the αB7-H3-αCD3 CSANs increase T cell infiltration and facilitate selective cytotoxicity of B7-H3+ medulloblastoma spheroids and that activity is independent of target cell MHC class I expression. Importantly, nonspecific T cell activation against the ONS 2303 medulloblastoma cell line can be reduced by tuning the valency of the αCD3 targeted monomer in the oligomerized CSAN. Intraperitoneal injections of αB7-H3-αCD3 bispecific CSANs were found to effectively cross the blood-tumor barrier into the brain and elicit significant antitumor T cell activity intracranially as well as systemically in an orthotopic medulloblastoma model. Moreover, following treatment with αB7-H3-αCD3 CSANs, intratumoral T cells were found to primarily have a central memory phenotype that displayed significant levels of characteristic activation markers. Collectively, these results demonstrate the ability of our multivalent, bispecific CSANs to direct potent antitumor T cell responses and indicate its potential utility as an alternative or complementary therapy for immune cell targeting of B7-H3+ brain tumors.

Abstract
Proteins are nature's primary building blocks for the construction of sophisticated molecular machines and dynamic materials, ranging from protein complexes such as photosystem II and nitrogenase that drive biogeochemical cycles to cytoskeletal assemblies and muscle fibers for motion. Such natural systems have inspired extensive efforts in the rational design of artificial protein assemblies in the last two decades. As molecular building blocks, proteins are highly complex, in terms of both their three-dimensional structures and chemical compositions. To enable control over the self-assembly of such complex molecules, scientists have devised many creative strategies by combining tools and principles of experimental and computational biophysics, supramolecular chemistry, inorganic chemistry, materials science, and polymer chemistry, among others. Owing to these innovative strategies, what started as a purely structure-building exercise two decades ago has, in short order, led to artificial protein assemblies with unprecedented structures and functions and protein-based materials with unusual properties. Our goal in this review is to give an overview of this exciting and highly interdisciplinary area of research, first outlining the design strategies and tools that have been devised for controlling protein self-assembly, then describing the diverse structures of artificial protein assemblies, and finally highlighting the emergent properties and functions of these assemblies.

Abstract
Multicellular biology is dependent on the control of cell-cell interactions. These concepts have begun to be exploited for engineering of cell-based therapies. Herein, we detail the use of a multivalent lipidated scaffold for the rapid and reversible manipulation of cell-cell interactions. Chemically self-assembled nanorings (CSANs) are formed via the oligomerization of bivalent dihydrofolate reductase (DHFR2) fusion proteins using a chemical dimerizer, bis-methotrexate. With targeting proteins fused onto the DHFR2 monomers, the CSANs can target specific cellular antigens. Here, anti-EGFR or anti-EpCAM fibronectin-DHFR2 monomers incorporating a CAAX-box sequence were enzymatically prenylated, then assembled into the corresponding CSANs. Both farnesylated and geranylgeranylated CSANs efficiently modified the cell surface of lymphocytes and remained bound to the cell surface with a half-life of >3 days. Co-localization studies revealed a preference for the prenylated nanorings to associate with lipid rafts. The presence of antigen targeting elements in these bifunctional constructs enabled them to specifically interact with target cells while treatment with trimethoprim resulted in rapid CSAN disassembly and termination of the cell-cell interactions. Hence, we were able to determine that activated PBMCs modified with the prenylated CSANs caused irreversible selective cytotoxicity toward EGFR-expressing cells within 2 hours without direct engagement of CD3. The ability to disassemble these nanostructures in a temporally controlled manner provides a unique platform for studying cell-cell interactions and T cell-mediated cytotoxicity. Overall, antigen-targeted prenylated CSANs provide a general approach for the regulation of specific cell-cell interactions and will be valuable for a plethora of fundamental and therapeutic applications.

Abstract
Overexpression of the epidermal growth factor receptor (EGFR) on various cancers makes it an important target for cancer immunotherapy. We recently demonstrated that single-chain variable fragment-based bispecific chemically self-assembled nanorings (CSANs) can successfully modify T cell surfaces and function as prosthetic antigen receptors (PARs) allowing selective targeting of tumor antigens while incorporating a dissociation mechanism of the rings. Here, we report the generation of anti-EGFR fibronectin (FN3)-based PARs with high yield, rapid protein production, predicted low immunogenicity, and increased protein stability. We demonstrated the cytotoxicity of FN3-PARs successfully while evaluating FN3 affinities, CSAN valencies, and antigen expression levels. Using an orthotopic breast cancer model, we showed that FN3-PARs can suppress tumor growth with no adverse effects and FN3-PARs reduced immunosuppressive programmed cell death ligand-1 (PD-L1) expression by downregulating EGFR signaling. These results demonstrate the potential of FN3-PARs to direct selective T cell-targeted tumor killing and to enhance antitumor T cell efficacy by modulating the tumor microenvironment.

Abstract
Protein assemblies are being investigated as a new-class of biomaterials. A supramolecular assembly of a mutant hexameric tyrosine coordinated hemoprotein (HTHP) modified with a pyrene derivative is described. Cysteine was first introduced as a site-specific reaction point at position V44 which is located at the bottom surface of the cylindrical structure of HTHP. [Formula: see text]-(1-pyrenyl)maleimide was then reacted with the mutant. The modification was confirmed by MALDI-TOF mass spectrometry and UV-vis absorption spectroscopy, indicating that approximately 90% cysteine residues are attached via the pyrene derivative. Size exclusion chromatography (SEC) measurements for pyrene-attached HTHP include a single peak which elutes earlier than the unmodified HTHP. Further investigation by SEC and dynamic light scattering (DLS) measurements indicate the desired size corresponding to the dimer of the hemoprotein hexamers. The multivalent effect of pyrene–pyrene interactions including hydrophobic and [Formula: see text]–[Formula: see text] stacking interactions appears to be responsible for including formation of the stable dimer of the hexamers. Interestingly, the assembly dissociates to the hexamer by removal of heme. In the case of the apo-form of pyrene-attached HTHP, the pyrene moiety appears to be incorporated into the heme pocket because the modification point is located at the adjacent residue of the Tyr45 coordinating to heme in the holo-form of HTHP. Subsequent addition of heme into the apo-form of pyrene-attached HTHP regenerates the dimer of the hexamers. The present study demonstrates a unique heme-dependent system in which HTHP is assembled to form a dimer of hexamers in the presence of heme and disassembled by removal of heme.

Abstract
Engineered cytochrome b562, a small hemoprotein, with an externally-attached heme moiety via a moderately long linker at a suitable position predominantly forms a thermodynamically stable ring-shaped trimer in dilute solution. In an equilibrium between supramolecular polymerization and depolymerization, the ring-shaped trimer is kinetically trapped even in a concentrated solution.

Abstract
Nature uses multivalency to govern many biological processes. The development of macromolecular and cellular therapies has largely been dependent on engineering similar polyvalent interactions to enable effective targeting. Such therapeutics typically utilize high-affinity binding domains that have the propensity to recognize both antigen-overexpressing tumors and normal-expressing tissues, leading to "on-target, off-tumor" toxicities. One strategy to improve these agents' selectivity is to reduce the binding affinity, such that biologically relevant interactions between the therapeutic and target cell will only exist under conditions of high avidity. Preclinical studies have validated this principle of avidity optimization in the context of chimeric antigen receptor (CAR) T cells; however, a rigorous analysis of this approach in the context of soluble multivalent targeting scaffolds has yet to be undertaken. Using a modular protein nanoring capable of displaying ≤8 fibronectin domains with engineered specificity for a model antigen, epithelial cell adhesion molecule (EpCAM), this study demonstrates that binding affinity and ligand valency can be optimized to afford discrimination between EpCAMHigh (2.8-3.8 × 106 antigens/cell) and EpCAMLow (5.2 × 104 to 2.2 × 105 antigens/cell) tissues both in vitro and in vivo.

Abstract
A supramolecular assembly of units of cytochrome b562 with externally attached heme having intermolecular linkages formed via the heme-heme pocket interaction was investigated in an effort to construct a well-defined structure. The engineered site for surface attachment of heme at Cys80 in an N80C mutant of cytochrome b562 provides the primary basis for the formation of the periodic assembly structure, which is characterized herein by circular dichroism (CD) spectroscopy and high-speed atomic force microscopy (AFM). This assembly represents the first example of the observation of a split-type Cotton effect by heme-heme exciton coupling in an artificial hemoprotein assembly system. Molecular dynamics simulations validated by simulated CD spectra, AFM images, and mutation experiments reveal that the assembly has a periodic helical structure with 3 nm pitches, suggesting the formation of the assembled structure is driven not only by the heme-heme pocket interaction but also by additional secondary hydrogen bonding and/or electrostatic interactions at the protein interfaces of the assembly.

Abstract
Our laboratory has developed chemically self-assembled nanorings (CSANs) as prosthetic antigen receptors (PARs) for the nongenetic modification of T cell surfaces. PARs have been successfully employed in vitro to activate T cells for the selective killing of leukemia cells. However, PAR efficacy has yet to be evaluated in vivo or against solid tumors. Therefore, we developed bispecific PARs that selectively target the human CD3 receptor and human epithelial cell adhesion molecule (EpCAM), which is overexpressed on multiple carcinomas and cancer stem cells. The αEpCAM/αCD3 PARs were found to stably bind T cells for >4 days, and treating EpCAM+ MCF-7 breast cancer cells with αEpCAM/αCD3 PAR-functionalized T cells resulted in the induction of IL-2, IFN-γ, and MCF-7 cytotoxicity. Furthermore, an orthotopic breast cancer model validated the ability of αEpCAM/αCD3 PAR therapy to direct T cell lytic activity toward EpCAM+ breast cancer cells in vivo, leading to tumor eradication. In vivo biodistribution studies demonstrated that PAR-T cells were formed in vivo and persist for over 48 h with rapid accumulation in tumor tissue. Following PAR treatment, the production of IL-2, IFN-γ, IL-6, and TNF-α could be significantly reduced by an infusion of clinically relevant concentrations of the FDA-approved antibiotic, trimethoprim, signaling pharmacologic PAR deactivation. Importantly, CSANs did not induce naïve T cell activation and thus exhibit a limited potential to induce naïve T cell anergy. In addition, murine immunogenicity studies demonstrated that CSANs do not induce a significant antibody response nor do they activate splenic cells. Collectively, our results demonstrate that bispecific CSANs are able to nongenetically generate reversibly modified T cells that are capable of eradicating targeted solid tumors.

Abstract
Protein crystals are formed via ordered arrangements of proteins, which assemble to form supramolecular structures. Here, we show a method for the assembly of supramolecular protein cages within a crystalline environment. The cages are stabilized by covalent cross-linking allowing their release via dissolution of the crystal. The high stability of the desiccated protein crystals allows cages to be constructed.

Abstract
Membrane-engineered cells displaying antigen-targeting ligands are useful as both scientific tools and clinical therapeutics. While genetically encoded artificial receptors have proven efficacious, their scope remains limited, as this approach is not amenable to all cell types and the modification is often permanent. Our group has developed a nongenetic method to rapidly, stably, and reversibly modify any cell membrane with a chemically self-assembled nanoring (CSAN) that can function as a prosthetic receptor. Bifunctional CSANs displaying epithelial cell adhesion molecule (EpCAM)-targeted fibronectin domains were installed on the cell membrane through hydrophobic insertion and remained stably bound for ≥72 h in vitro. These CSAN-labeled cells were capable of recognizing EpCAM-expressing target cells, forming intercellular interactions that were subsequently reversed by disassembling the nanoring with the FDA-approved antibiotic, trimethoprim. This study demonstrates the use of this system to engineer cell surfaces with prosthetic receptors capable of directing specific and reversible cell-cell interactions.

Abstract
A specific and reversible method is reported to engineer cell-membrane function by embedding DNA-origami nanodevices onto the cell surface. Robust membrane functionalization across epithelial, mesenchymal, and nonadherent immune cells is achieved with DNA nanoplatforms that enable functions including the construction of higher-order DNA assemblies at the cell surface and programed cell-cell adhesion between homotypic and heterotypic cells via sequence-specific DNA hybridization. It is anticipated that integration of DNA-origami nanodevices can transform the cell membrane into an engineered material that can mimic, manipulate, and measure biophysical and biochemical function within the plasma membrane of living cells.

Abstract
Multi-enzyme complexes have the potential to achieve high catalytic efficiency for sequence reactions due to their advantages in eliminating product inhibition, facilitating intermediate transfer and in situ regenerating cofactors. Constructing functional multi-enzyme systems to mimic natural multi-enzyme complexes is of great interest for multi-enzymatic biosynthesis and cell-free synthetic biotransformation, but with many challenges. Currently, various assembly strategies have been developed based on the interaction of biomacromolecules such as DNA, peptide and scaffolding protein. On the other hand, chemical-induced assembly is based on the affinity of enzymes with small molecules including inhibitors, cofactors and metal ions has the advantage of simplicity, site-to-site oriented structure control and economy. This review summarizes advances and progresses employing these strategies. Furthermore, challenges and perspectives in designing multi-enzyme systems are highlighted.

Abstract
The promotion of protein dimerization using the aggregation properties of a protein ligand was explored and shown to produce complexes with unusual stoichiometries. Helical foldamer 2 was synthesized and bound to human carbonic anhydrase (HCA) using a nanomolar active site ligand. Crystal structures show that the hydrophobicity of 2 and interactions of its side chains lead to the formation of an HCA2-23 complex in which three helices of 2 are stacked, two of them being linked to an HCA molecule. The middle foldamer in the stack can be replaced by alternate sequences 3 or 5. Solution studies by CD and NMR confirm left-handedness of the helical foldamers as well as HCA dimerization.

Abstract
We have previously reported that cationic poly-arginine and arginine-rich cell-penetrating peptides display high-level neuroprotection and reduce calcium influx following in vitro excitotoxicity, as well as reduce brain injury in animal stroke models. Using the neuroprotective peptides poly-arginine R12 (R12) and the NR2B9c peptide fused to the arginine-rich carrier peptide TAT (TAT-NR2B9c; also known as NA-1), we investigated the mechanisms whereby poly-arginine and arginine-rich peptides reduce glutamate-induced excitotoxic calcium influx. Using cell surface biotin protein labeling and western blot analysis, we demonstrated that R12 and TAT-NR2B9c significantly reduced cortical neuronal cell surface expression of the NMDA receptor subunit NR2B. Chemical endocytic inhibitors used individually or in combination prior to glutamate excitotoxicity did not significantly affect R12 peptide neuroprotective efficacy. Similarly, pretreatment of neurons with enzymes to degrade anionic cell surface proteoglycans, heparan sulfate proteoglycan (HSPG), and chondroitin sulfate proteoglycan (CSPG), as well as sialic acid residues, did not significantly affect peptide neuroprotective efficacy. While the exact mechanisms responsible for R12 peptide-mediated NMDA receptor NR2B subunit cell surface downregulation were not identified, an endocytic process could not be ruled out. The study supports our hypothesis that arginine-rich peptides reduce excitotoxic calcium influx by reducing the levels of cell surface ion channels.

Abstract
Chemically self-assembled nanorings (CSANs) are made of dihydrofolate reductase (DHFR) fusion proteins and have been successfully used in vitro for cellular cargo delivery and cell surface engineering applications. However, CSANs have yet to be evaluated for their in vivo stability, circulation, and tissue distribution. In an effort to evaluate CSANs in vivo, we engineered a site-specifically PEGylated epidermal growth factor receptor (EGFR) targeting DHFR molecules, characterized their self-assembly into CSANs with bivalent methotrexates (bis-MTX), visualized their in vivo tissue localization by microPET/CT imaging, and determined their ex vivo organ biodistribution by tissue-based gamma counting. A dimeric DHFR (DHFR(2)) molecule fused with a C-terminal EGFR targeting peptide (LARLLT) was engineered to incorporate a site-specific ketone functionality using unnatural amino acid mutagenesis. Aminooxy-PEG, of differing chain lengths, was successfully conjugated to the protein using oxime chemistry. These proteins were self-assembled into CSANs with bis-MTX DHFR dimerizers and characterized by size exclusion chromatography and dynamic light scattering. In vitro binding studies were performed with fluorescent CSANs assembled using bis-MTX-FITC, while in vivo microPET/CT imaging was performed with radiolabeled CSANs assembled using bis-MTX-DOTA[(64)Cu]. PEGylation reduced the uptake of anti-EGFR CSANs by mouse macrophages (RAW 264.7) up to 40% without altering the CSAN's binding affinity toward U-87 MG glioblastoma cells in vitro. A significant time dependent tumor accumulation of (64)Cu labeled anti-EGFR-CSANs was observed by microPET/CT imaging and biodistribution studies in mice bearing U-87 MG xenografts. PEGylated CSANs demonstrated a reduced uptake by the liver, kidneys, and spleen resulting in high contrast tumor imaging within an hour of intravenous injection (9.6% ID/g), and continued to increase up to 24 h (11.7% ID/g) while the background signal diminished. CSANs displayed an in vivo profile between those of rapidly clearing small molecules and slow clearing antibodies. Thus, CSANs offer a modular, programmable, and stable protein based platform that can be used for in vivo drug delivery and imaging applications.

Abstract
Supramolecular assembly of a beta-barrel protein via cucurbit[8]uril results in compact z-shaped protein dimers. SAXS data reveal the formation of a well ordered protein dimer, notwithstanding being connected by a reversible and flexible peptide linker, and highlight the supramolecular induced interplay of the proteins, analogous to covalently linked proteins.

Abstract
Stable protein one (SP1) has been demonstrated as an appealing building block to design highly ordered architectures, despite the hybrid assembly with other nano-objects still being a challenge. Herein, we developed a strategy to construct high-ordered protein nanostructures by electrostatic self-assembly of cricoid protein nanorings and globular quantum dots (QDs). Using multielectrostatic interactions between 12mer protein nanoring SP1 and oppositely charged CdTe QDs, highly ordered nanowires with sandwich structure were achieved by hybridized self-assembly. QDs with different sizes (QD1, 3-4 nm; QD2, 5-6 nm; QD3, ∼10 nm) would induce the self-assembly protein rings into various nanowires, subsequent bundles, and irregular networks in aqueous solution. Atomic force microscopy, transmission electron microscopy, and dynamic light scattering characterizations confirmed that the size of QDs and the structural topology of the nanoring play critical functions in the formation of the superstructures. Furthermore, an ordered arrangement of QDs provides an ideal scaffold for designing the light-harvesting antenna. Most importantly, when different sized QDs (e.g., QD1 and QD3) self-assembled with SP1, an extremely efficient Förster resonance energy transfer was observed on these protein nanowires. The self-assembled protein nanostructures were demonstrated as a promising scaffold for the development of an artificial light-harvesting system.

Abstract
Construction of heterofunctional proteins is a rapidly emerging area of biotherapeutics. Combining a protein with other moieties, such as a targeting element, a toxic protein or small molecule, and a fluorophore or polyethylene glycol (PEG) group, can improve the specificity, functionality, potency, and pharmacokinetic profile of a protein. Protein farnesyl transferase (PFTase) is able to site-specifically and quantitatively prenylate proteins containing a C-terminal CaaX-box amino acid sequence with various modified isoprenoids. Here, we describe the design, synthesis, and application of a triorthogonal reagent, 1, that can be used to site-specifically incorporate an alkyne and aldehyde group simultaneously into a protein. To illustrate the capabilities of this approach, a protein was enzymatically modified with compound 1 followed by oxime ligation and click reaction to simultaneously incorporate an azido-tetramethylrhodamine (TAMRA) fluorophore and an aminooxy-PEG moiety. This was performed with both a model protein [green fluorescent protein (GFP)] as well as a therapeutically useful protein [ciliary neurotrophic factor (CNTF)]. Next, a protein was enzymatically modified with compound 1 followed by coupling to an azido-bis-methotrexate dimerizer and aminooxy-TAMRA. Incubation of that construct with a dihydrofolate reductase (DHFR)-DHFR-anti-CD3 fusion protein resulted in the self-assembly of nanoring structures that were endocytosed into T-leukemia cells and visualized therein. These results highlight how complex multifunctional protein assemblies can be prepared using this facile triorthogonal approach.

Abstract
Synthetic nucleic acids have shown great potential in the treatment of various diseases. Nevertheless, the selective delivery to a target tissue has proved challenging. The coupling of nucleic acids to targeting peptides, proteins, and antibodies has been explored as an approach for their selective tissue delivery. Nevertheless, the preparation of covalently coupled peptides and proteins that can also undergo intracellular release as well as deliver more than one copy of the nucleic acid has proved challenging. Recently, we have developed a novel method for the rapid noncovalent conjugation of nucleic acids to targeting single chain antibodies (scFv) using chemically self-assembled nanostructures (CSANs). CSANs have been prepared by the self-assembly of two dihydrofolate reductase molecules (DHFR(2)) and a targeting scFv in the presence of bis-methotrexate (bis-MTX). The valency of the nanorings can be tuned from one to eight subunits, depending on the length and composition of the linker between the dihydrofolate reductase molecules. To explore their potential for the therapeutic delivery of nucleic acids as well as the ability to expand the capabilities of CSANs by incorporating smaller cyclic targeting peptides, we prepared DHFR(2) proteins fused through a flexible peptide linker to cyclic-RGD, which targets αvβ3 integrins, and a bis-MTX chemical dimerizer linked to an antisense oligonucleotide (bis-MTX-ASO) that has been shown to silence expression of eukaryotic translation initiation factor 4E (eIF4E). Monomeric and multimeric cRGD-CSANs were then prepared with bis-MTX-ASO and shown to undergo endocytosis in the breast cancer cell line, MDA-MB-231, which overexpresses αvβ3. The bis-MTX-ASO was shown to undergo endosomal escape resulting in the knock down of eIF4E with at least the same efficiency as ASO delivered by oligofectamine. The modularity, flexibility, and common method of conjugation may prove to be a useful general approach for the targeted delivery of ASOs, as well as other nucleic acids to cells.

Abstract
The precise accumulation of protein functions on a nanoscale to fabricate advanced biomaterials has become possible by a bottom-up approach based on molecular self-assembly. The avidin-biotin interaction is widely employed in the design of functional protein self-assemblies. Herein we assessed how the spatial arrangement of the avidin-biotin interaction between protein building blocks affects the formation of a protein supramolecular complex (PSC). The enzymatic site-specific internal labeling of a symmetric protein scaffold, bacterial alkaline phosphatase (AP), with specifically designed biotinylation substrates revealed that the precise positioning of the biotinylation sites on AP and the linker flexibility of the substrate are critical factors for the growth of PSCs in the presence of streptavidin (SA). A potential diagnostic application of the PSCs comprised of AP and SA was demonstrated in an enzyme-linked immunosorbent assay.

Abstract
A native protein in a biological system spontaneously produces large and elegant assemblies via self-assembly or assembly with various biomolecules which provide non-covalent interactions. In this context, the protein plays a key role in construction of a unique supramolecular structure operating as a functional system. Our group has recently highlighted the structure and function of hemoproteins reconstituted with artificially created heme analogs. The heme molecule is a replaceable cofactor of several hemoproteins. Here, we focus on the successive supramolecular protein assemblies driven by heme-heme pocket interactions to afford various examples of protein fibers, networks and three-dimensional clusters in which an artificial heme moiety is introduced onto the surface of a hemoprotein via covalent linkage and the native heme cofactor is removed from the heme pocket. This strategy is found to be useful for constructing hybrid materials with an electrode or with nanoparticles. The new systems described herein are expected to lead to the generation of various biomaterials with functions and characteristic physicochemical properties similar to those of hemoproteins.

Abstract
Chemically self-assembled antibody nanorings (CSANs) displaying multiple copies of single-chain variable fragments can be prepared from dihydrofolate reductase (DHFR) fusion proteins and bis-methotrexate (bisMTX). We have designed and synthesized a bisMTX chemical dimerizer (bisMTX-NH(2)) that contains a third linker arm that can be conjugated to fluorophores, radiolabels, and drugs. Monovalent, divalent, and higher-order AntiCD3 CSANs were assembled with a fluorescein isothiocyanate (FITC)-labeled bis-methotrexate ligand (bisMTX-FITC) and found to undergo rapid internalization and trafficking by HPB-MLT, a CD3+ T-leukemia cell line, to the early and late endosome and lysosome. Because the fluorescence of bisMTX-FITC when incorporated into CSANs was found to be significantly greater than that of the free ligand, the stability of the endocytosed AntiCD3 CSANs could be monitored. The internalized CSANs were found to be stable for several hours, while treatment with the nontoxic DHFR inhibitor trimethoprim resulted in a rapid loss (>80%) of cellular fluorescence within minutes, consistent with efficient intracellular disassembly of the nanorings. Over longer time periods (24 h), cellular fluorescence decreased by 75-90%, regardless of whether cells had been treated with DMSO or trimethoprim. Although bisMTX is a potent inhibitor of DHFR, it was found to be nontoxic (GI(50) > 20 μM) to HPB-MLT cells. In contrast, AntiCD3 CSANs prepared with bisMTX were found to be at least 13-fold more cytotoxic (GI(50) = 0.5-1.5 μM) than bisMTX at 72 h. Consistent with our findings from CSAN stability studies, no increase in cytotoxicity was observed upon treatment with trimethoprim. Taken together, our results suggest that cell receptor targeting CSANs prepared with trifunctional bisMTX could be used as potential tissue selective drug carriers.

Abstract
Synthetic immunology, the development of synthetic systems capable of modulating and/or manipulating immunological functions, represents an emerging field of research with manifold possibilities. One focus of this area has been to create low molecular weight synthetic species, called antibody-recruiting molecules (ARMs), which are capable of enhancing antibody binding to disease-relevant cells or viruses, thus leading to their immune-mediated clearance. This article provides a thorough discussion of contributions in this area, beginning with the history of small-molecule-based technologies for modulating antibody recognition, followed by a systematic review of the various applications of ARM-based strategies. Thus, we describe ARMs capable of targeting cancer, bacteria, and viral pathogens, along with some of the scientific discoveries that have resulted from their development. Research in this area underscores the many exciting possibilities at the interface of organic chemistry and immunobiology and is positioned to advance both basic and clinical science in the years to come.
