Publication number: 20210350875Abstract: Disclosed is a high-throughput method and system for mapping or screening biomolecular interactions, where the method includes providing a plurality of cells, or in some examples purified proteins themselves, expressing a phase separation or aggregation system, including those capable of being controlled by at least one wavelength of light, with the phase separation or aggregation system comprising a target protein possibly fused to a fluorescent protein. The cells are placed in a well, and chemical and/or biological agent are then introduced to the well.Type: ApplicationFiled: September 19, 2019Publication date: November 11, 2021Applicant: The Trustees of Princeton UniversityInventors: Cliff Brangwynne, Dan Bracha, Chanelle Jumper, Paul Ackerman

Publication number: 20210292735Abstract: A protein construct including a gene encoding a light-sensitive protein fused to at least one of either a low complexity sequence, an intrinsically disordered protein region (IDR), or a repeating sequence of a linker and another gene encoding a light-sensitive protein. Among the many different possibilities contemplated, the protein construct may also advantageously include cleavage tags. This protein construct may be utilized for a variety of functions, including a method for protein purification, which requires introducing the protein construct into a living cell, and inducing the formation of clusters by irradiating the construct with light. The method may also advantageously include cleaving a target protein from an IDR, and separating the clusters via centrifuge. A kit for practicing in vivo aggregation or liquid-liquid phase separation is also included, the kit including the protein construct and a light source capable of producing a wavelength that the light-sensitive protein will respond to.Type: ApplicationFiled: June 4, 2021Publication date: September 23, 2021Applicant: The Trustees of Princeton UniversityInventors: Cliff Brangwynne, Jared Toettcher, Yongdae Shin

Publication number: 20210292737Abstract: A system and method for reversibly controlling clustering of proteins around an engineered multivalent nucleus is disclosed. The system and method utilize clustering, which may be controlled by light activation or deactivation. The system and method enable the spatiotemporal control of protein supramolecular assemblies, including liquid-like droplets under some conditions, and solid-like gels under other conditions. The system and method can be utilized for segregating or locally concentrating desired proteins and/or RNA in cells or cell lysate, which may be useful for protein purification purposes, or for assembling single or multiple membraneless bodies within specific sub-regions of the cells. These synthetically assembled bodies may recruit both transgenic and endogenic proteins and other biomolecules, thus can be linked to affect and even trigger a plethora of cellular processes, including both physiological and pathological (e.g., protein aggregation) processes.Type: ApplicationFiled: June 1, 2021Publication date: September 23, 2021Applicant: The Trustees of Princeton UniversityInventors: Cliff Brangwynne, Dan Bracha

Publication number: 20210269780Abstract: A system and method for modulating stress granule assembly, utilizing a protein construct that has a cell penetrating protein fused to one or more proteins that can bind with an NTF2-like domain of a G3BP protein. By configuring the protein construct with an appropriate number of proteins that being with NTF2-like domains, stress granule assembly can be upregulated or downregulated as needed to treat patients.Type: ApplicationFiled: July 12, 2019Publication date: September 2, 2021Applicant: The Trustees of Princeton UniversityInventors: Cliff Brangwynne, Victoria Drake, David Sanders

Publication number: 20210047659Abstract: Disclosed is a system and method for the controlled clustering of gene regulatory proteins at the specific target genomic loci. The technology enables formation of liquid-like droplets closely interfaced with genome organization. This technology can be utilized for perturbing endogenous nuclear structures as well as nucleating synthetic membrane-less assemblies. The technology can also be utilized for inducing or detecting mechanical stresses within the genome.Type: ApplicationFiled: January 23, 2019Publication date: February 18, 2021Applicant: The Trustees of Princeton UniversityInventors: Cliff BRANGWYNNE, Yongdae SHIN, Dan BRACHA
