(SD2020-266) Protein Domains For Modulation Of Rna Stability And/Or Translation

Existing art in modulation of gene expression by nucleic acid targeting mechanisms primarily comprises methods for REDUCING gene expression, e.g. via DNA targeting (CRISPR gene knockout, reduction of transcription via CRISPR-i), or RNA targeting (shRNAs/siRNAs, ASOs, microRNA mimics). ENHANCEMENT of gene expression on the RNA level has been achieved using microRNA inhibitors; however the effects are typically small and are not target-specific (many other microRNA target-RNAs are also upregulated).The molecular functions of the majority of RNA-binding proteins (RBPs) remain unclear, highlighting a major bottleneck to a full understanding of gene expression regulation.

Improved guide RNA and Protein Design for CasX-based Gene Editing Platform

The inventors have developed two new CasX gene-editing platforms (DpbCasXv2 and PlmCasXv2) through rationale structural engineering of the CasX protein and gRNA, which yield improved in vitro and in vivo behaviors. These platforms dramatically increase DNA cleavage activity and can be used as the basis for further improving CasX tools.The RNA-guided CRISPR-associated (Cas) protein CasX has been reported as a fundamentally distinct, RNA-guided platform compared to Cas9 and Cpf1. Structural studies revealed structural differences within the nucleotide-binding loops of CasX, with a compact protein size less than 1,000 amino acids, and guide RNA (gRNA) scaffold stem. These structural differences affect the active ternary complex assembly, leading to different in vivo and in vitro behaviors of these two enzymes.

The inventors demonstrate the utility of this system by modifying Cas9 and other proteins with fluorophores, peptides, and whole proteins, such as green fluorescent proteins (GFPs) and antibody short chain variable fragments. This technology represents a novel paradigm in biomolecule coupling.

Methods To Suppress Viral Infection Of Mammalian Cells

To meet the ever-growing demand for effective, safe, and affordable protein therapeutics, decades of intense efforts have aimed to maximize the quantity and quality of recombinant proteins produced in Chinese hamster ovary (CHO) cells. CHO cells are extensively used to produce biopharmaceuticals and one advantage is their reduced susceptibility to many human virus families. However, there have been a few episodes of animal viral contamination of biopharmaceutical production runs, mostly from trace levels of viruses in raw materials. These infections more often caused by RNA viruses have led to expensive decontamination efforts and threatened the supply of critical drugs. Viral contamination in biopharmaceutical manufacturing can lead to shortages in the supply of critical therapeutics. Therefore there is a need to understand the mechanisms by which CHO cells are infected and how the cells can be universally engineered to enhance their viral resistance.

Living Bioreactor for Stoichiometric Protein Production

Living bioreactors are powerful systems for producing a variety of valuable compounds. The versatility of such bioreactors is one of the more useful aspects of the system. Large quantities of compounds or cellular components can be produced efficiently, with minimal cost. Alternately, these systems can be used to produce pathway components that are necessary in the production of secondary products. A common problem with such systems is that they are limited by non-uniform production of pathway components, or require an isolation process to ensure the components are in the appropriate quantity and sequence in the process. Inventors at Texas A&M and UC San Francisco have developed a novel technique to address these issues. The technology effectively results in a stoichiometric production of protein components that are produced in an array, ready for secondary production.

In Situ Lipid Synthesis for Protein Reconstitution (INSYRT)

While current methods for membrane protein functional reconstitution in biomimetic membranes approaches are powerful and have uncovered fundamental properties of protein function, they are methodologically cumbersome, requiring chromatography steps to remove detergents. Moreover, structural features normally found in cell membranes such as curvature and polarity are mostly absent. In this regard, an efficient reconstitution methodology that better mimics the native chemical environment of a whole-cell embedded protein would be highly useful.

Mammalian Cell Culture Optimization

Biotherapeutic proteins manufactured in cell culture systems have transformed modern medicine. Selling many tens of billions per year, new biotherapeutics such as monoclonal antibodies have delivered dramatic clinical results, while posing significant manufacturing problems.: During the cell culture manufacturing process, toxic bioproducts such as lactate and ammonia have posed considerable challenges in bioprocessing, since they limit cell growth and impact critical quality attributes of recombinant protein production (e.g., therapeutic drugs, enzymes). That is because the lactate alters the regulation of biosynthetic enzymes, and can lead to changes in pH in the culture. To mitigate the negative effects of lactic acid accumulation and control the culture pH, chemical ‘base’ is added to the media during the course of a bioprocess. However, the base addition negatively impacts the bioprocess by inhibiting growth and shortening the length of time in which the cells can produce the recombinant protein. This leads to reduced yield, and increased cost-of-goods. Thus, it is of great interest to eliminate lactate production, and UC San Diego researchers have recently developed a new process for achieving this.  

Dual Targeting Agents For Alzheimer's Disease

Alzheimer’s Disease is a prevalent neurodegenerative disorder affecting 10% of people over age 65. It is characterized by a progressive loss of cognitive function and memory impairments that are associated with increased peptide and protein aggregation in the brain.

Preventing Protein Aggregation using Thermal Protectants

Protein aggregation in the brain are the causes of the neurodegenerative diseases Alzheimer’s and Parkinson’s. To study diseases and cellular mechanisms, biologists need to be able to efficiently synthesize, isolate and purify proteins. The invention herein is a synthetic nanoparticle (NP) that protects proteins from aggregation at temperatures, which normally cause aggregation. Furthermore, multiple stimuli can release the protein in high yield from the NPs.
