Abstract: The application discloses multimeric assemblies including multiple oligomeric substructures, where each oligomeric substructure includes multiple proteins that self-interact around at least one axis of rotational symmetry, where each protein includes one or more polypeptide-polypeptide interface (“O interface”); and one or more polypeptide domain that is capable of effecting membrane scission and release of an enveloped multimeric assembly from a cell by recruiting the ESCRT machinery to the site of budding by binding to one or more proteins in the eukaryotic ESCRT complex (“L domain”); and where the multimeric assembly includes one or more subunits comprising one or more polypeptide domain that is capable of interacting with a lipid bilayer (“M domain”), as well as membrane-enveloped versions of the multimeric assemblies.

Abstract: The preset disclosure provides chimeric polypeptides comprising a cage polypeptide comprising a degron, wherein the degron is sequestered or caged. Upon activation by a key polypeptide, the degron becomes active. The degron can recruit an ubiquitin ligase and a lysine in the degron or surrounding sequence be ubiquitinated. The ubiquitinated chimeric polypeptide is marked for degradation, together with any biologically active molecule attached to the chimeric polypeptide. The chimeric polypeptides of the present disclosure can be incorporated, for example, to chimeric antigen receptors (CAR). Accordingly, in response to the administration of a key polypeptide or endogenous expression of a key polypeptide mediated, for example, by an inducible promoter, the amount of CAR expressed on the surface of an immune cell can be modulated.

Abstract: The present disclosure relates to polynucleotides encoding a chimeric polypeptide comprising a c-Jun polypeptide, a ROR1-binding protein, and a truncated EGF receptor. Also provided are cells (e.g., T cells) expressing CARs comprising a ROR1-binding protein and overexpressing a c-Jun polypeptide. Overexpression of c-Jun in CAR T cells confers improved properties, e.g., reducing or preventing exhaustion.

Abstract: Disclosed herein are polynucleotides comprising a nucleotide sequence encoding an AP-1 transcription factor (i.e., c-Jun). In some aspects, the nucleotide sequence is codon-optimized. In some aspects, the polynucleotides comprise one or more additional nucleotide sequences encoding a linker, signal peptide, antigen-binding domain, spacer, transmembrane domain, costimulatory domain, intracellular signaling domain, truncated EGFR, and combinations thereof. Also disclosed herein are cells, vectors, and pharmaceutical compositions comprising such polynucleotides. The use of such polynucleotides, cells, vectors, and pharmaceutical compositions to treat a disease or disorder (e.g., cancer) is also provided.

Abstract: Provided are molecular feedback circuits employing caged-degrons. Aspects of such circuits include the use of a caged-degron to modulate the output of a signaling pathway in a feedback-controlled manner. Also provided are nucleic acids encoding molecular circuits and cells containing such nucleic acids. Methods of using caged-degron-based molecular feedback circuits are also provided, including e.g., methods of modulating a signaling pathway of a cell that include genetically modifying the cell with a caged-degron-based molecular feedback circuit.

Abstract: Gene editing can be performed by introducing gene-editing components into a cell by mechanical cell disruption. Related apparatus, systems, techniques, and articles are also described.

Abstract: Disclosed herein are non-naturally occurring cage polypeptides, kits and degron LOCKRs including the cage polypep-tides, and uses thereof, wherein the cage polypeptides include (a) a helical bundle, comprising between 2 and 7 alpha-helices, wherein the helical bundle includes: (i) a structural region; and (ii) a latch region, wherein the latch region composes a degron located within the latch region, wherein the structural region interacts with the latch region to prevent activity of the degron; and (b) amino acid linkers connecting each alpha helix

Abstract: Gene editing can be performed by introducing gene-editing components into a cell by mechanical cell disruption. Related apparatus, systems, techniques, and articles are also described. The methods and systems of the invention solve the problem of intracellular delivery of gene editing components and gene editing complexes to target cells. The results described herein indicate that delivery of gene editing components, e.g., protein, ribonucleic acid (RNA), and deoxyribonucleic acid (DNA), by mechanical disruption of cell membranes leads to successful gene editing. Because intracellular delivery of gene editing materials is a current challenge, the methods provide a robust mechanism to engineer target cells without the use of potentially harmful viral vectors or electric fields.
