Publication number: 20240035017Abstract: Some aspects of this disclosure provide compositions, strategies, systems, reagents, methods, and kits that are useful for the targeted editing of nucleic acids, including editing a single site within the genome of a cell or subject, e.g., within the human genome. In some embodiments, fusion proteins capable of inducing a cytosine (C) to guanine (G) change in a nucleic acid (e.g., genomic DNA) are provided. In some embodiments, fusion proteins of a nucleic acid programmable DNA binding protein (e.g., Cas9) and nucleic acid editing proteins or protein domains, e.g., deaminase domains, polymerase domains, and/or base excision enzymes are provided. In some embodiments, methods for targeted nucleic acid editing are provided. In some embodiments, reagents and kits for the generation of targeted nucleic acid editing proteins, e.g., fusion proteins of a nucleic acid programmable DNA binding protein (e.g., Cas9), and nucleic acid editing proteins or domains, are provided.Type: ApplicationFiled: November 28, 2022Publication date: February 1, 2024Applicant: President and Fellows of Harvard CollegeInventors: David R. Liu, Luke W. Koblan

Publication number: 20230193295Abstract: Provided herein are systems, compositions, and methods for the incorporation of unnatural amino acids into proteins via nonsense suppression or rare codon suppression. Nonsense codons and rare codons may be introduced into the coding sequence of a protein of interest using a CRISPR/Cas9-based nucleobase editor described herein. The nucleobase editors are able to be programmed by guide nucleotide sequences to edit the target codons in the coding sequence of the protein of interest. Also provided are application enabled by the technology described herein.Type: ApplicationFiled: November 14, 2022Publication date: June 22, 2023Applicant: President and Fellows of Harvard CollegeInventors: Juan Pablo Maianti, David R. Liu, Luke W. Koblan

Publication number: 20210198330Abstract: Some aspects of this disclosure provide strategies, systems, reagents, methods, and kits that are useful for the targeted editing of nucleic acids, including editing a single site within the genome of a cell or subject, e.g., within the human genome. The disclosure provides fusion proteins of nucleic acid programmable DNA binding proteins (napDNAbp), e.g., Cas9 or variants thereof, and nucleic acid editing proteins such as cytidine deaminase domains (e.g., novel cytidine deaminases generated by ancestral sequence reconstruction), and adenosine deaminases that deaminate adenine in DNA. Aspects of the disclosure relate to fusion proteins (e.g., base editors) that have improved expression and/or localize efficiently to the nucleus. In some embodiments, base editors are codon optimized for expression in mammalian cells. In some embodiments, base editors include multiple nuclear localization sequences (e.g., bipartite NLSs), e.g., at least two NLSs.Type: ApplicationFiled: May 23, 2019Publication date: July 1, 2021Applicants: The Broad Institute, Inc., President and Fellows of Harvard CollegeInventors: David R.
