Abstract:
Methods and systems for computationally designing self-assembling polypeptides are disclosed. A representation of a docked configuration of a symmetric protein architecture can be determined by a computing device configured to computationally symmetrically dock representations of protein building blocks within a representation of a symmetric protein architecture, where symmetrically docking a representation of a particular protein building block can include determining a configuration of the protein building blocks in three-dimensional space within the symmetric protein architecture configured to generate interfaces between building blocks suitable for computational protein interface design. The amino acid sequence of the docked protein building blocks can be computationally modified to specify protein-protein interfaces between the plurality of protein building blocks that are energetically favorable to drive self-assembly of a protein that includes the modified amino acid sequence.
Abstract:
The present disclosure provides nanostructures and nanostructure-based vaccines. Some nanostructures of the present disclosure display antigens capable of eliciting immune responses to infectious agents such as bacteria, viruses, and pathogens. Some vaccines of the present disclosure are useful for preventing or decreasing the severity of infection with an infectious agent, including. for example and without limitation, lyme disease, pertussis, herpes virus, orthomyxovirus, paramyxovirus, pneumovirus, filovirus. flavivirus, reovirus, retrovirus, meningococcus, or malaria. The antigens may be attached to the core of the nanostructure either non-covalently or covalently, including as a fusion protein or by other means disclosed herein. Multimeric antigens may optionally be displayed along a symmetry axis of the nanostructure. Also provided are proteins and nucleic acid molecules encoding such proteins. vaccine compositions, and methods of administration.

Abstract:
The present invention relates to methods and compositions for the high throughput screening of protein-protein interactions in yeast liquid culture. Protein fusions non-native to yeast may be expressed to replace endogenous sexual agglutination proteins and mediate library-by-library interrogation of protein interactions. The methods and compositions of the invention can be utilized for the characterization of protein interaction networks in high throughput for both binding affinity and specificity, which is crucial for understanding cellular functions, screening therapeutic candidates, and evaluating engineered protein networks.
