     BACKGROUND 
     Precise genome targeting technologies using the CRISPR/Cas9 system have recently been explored in a wide range of applications, including gene therapy. A major limitation to the application of Cas9 and Cas9-based genome-editing agents in gene therapy is the size of Cas9 (&gt;4 kb), impeding its efficient delivery via recombinant adeno-associated virus (rAAV). 
     SUMMARY 
     Described herein are systems, compositions, kits, and methods for delivering a Cas9 protein or a nucleobase editor to cells, e.g., via recombinant adeno-associated virus vectors. Typically a Cas9 protein or a nucleobase editor is “split” into an N-terminal portion and a C-terminal portion. The N-terminal portion or C-terminal portion of a Cas9 protein or a nucleobase editor may be fused to one member of the intein system, respectively. The resulting fusion proteins, when delivered on separate vectors (e.g., separate rAAV vectors) into one cell and co-expressed, may be joined to form a complete and functional Cas9 protein or nucleobase editor (e.g., via intein-mediated protein splicing). Further provided herein are empirical testing of regulatory elements in the delivery vectors for high expression levels of the split Cas9 protein or the nucleobase editor. 
     Some aspects of the present disclosure provide compositions comprising: (i) a first nucleotide sequence encoding a N-terminal portion of a Cas9 protein fused at its C-terminus to an intein-N; and (ii) a second nucleotide sequence encoding an intein-C fused to the N-terminus of a C-terminal portion of the Cas9 protein, wherein the first nucleotide sequence or second nucleotide sequence is operably linked to a nucleotide sequence encoding at least one bipartite nuclear localization signal.

       BRIEF DESCRIPTION OF THE DRAWINGS 
       The accompanying drawings, which constitute a part of this Application, illustrate several embodiments of the invention and together with the description, serve to explain the principles of the invention. 
         FIGS. 1A-1C  are graphs showing a “split nucleobase editor” for delivery into cells using recombinant adeno associated virus (rAAV) vectors.  FIG. 1A  is a schematic representation of how the nucleobase editor is split into two portions.  FIG. 1B  shows that AAV-delivered split nucleobase editor can undergo protein splicing upon expression of the two halves in cells to form a complete nucleobase editor that has comparable activity to a nucleobase editor expressed as a whole.  FIG. 1C  shows the formation of a complete nucleobase editor from the two halves via protein splicing mediated by DnaE intein. 
         FIG. 2  shows that U1118 cells were efficiently transfected by AAV2 containing nucleic acids encoding mCherry. Different viral titers were tested (2.5-10 μl at 4.5×10 11  vg/ml*) and all resulted in efficient transfection of U118 cells. *vg/ml means viral genome-containing particles per microliter. 
         FIGS. 3A-3B  are graphs showing high throughput sequence (HTS) results of nucleobase editing by rAAV-delivered split nucleobase editor in U118 and HEK cells. Lipid-transfected nucleobase editor was used as a control. A sgRNA targeting R37 in the PRNP gene was used, and the PRNP gene locus was sequenced.  FIG. 3A  shows the HTS reads, and  FIG. 3B  summarizes the base editing results. 
         FIG. 4  is a graph showing the optimization of the transcriptional terminator used in the AAV constructs encoding the split nucleobase editor. Transcriptional terminators of different sizes and origins were tested. bGH transcriptional terminator is relatively short and efficiently terminates transcription comparably to longer terminator sequences. It was therefore chosen to be used in the downstream experiments. 
         FIGS. 5A-5B  are graphs showing the results of nucleobase editing with long term (up to 15 days) transduction of AAV encoding the split nucleobase editor in mouse astrocytes expressing human ApoE4 cDNA. The target base is in the codon for arginine 112 and arginine 158 in ApoE4, which is converted to a cysteine upon base editing.  FIG. 5A  shows that the editing of arginine 158 increases overtime when the mouse astrocytes were transduced at 10 10  vg, while editing of arginine 112 remained minimal. The nucleotide sequence 3′ of the codon for arginine 158 sequence features a flanking NGG PAM allowing for high activity by SpCas9 (with guide sequence GAAGCGCCTGGCAGTGTACC, SEQ ID NO: 348), while the nucleotide sequence 3′ of the codon for arginine 112 contains a flanking NAG PAM which does not allow for high activity (with guide sequence GACGTGCGCGGCCGCCTGGTG, SEQ ID NO: 349).  FIG. 5B  shows cells transduced with rAAV encoding mCherry at 10 10  vg (control). 
         FIG. 6  is a schematic representation of the optimization of the nuclear localization signal in AAV constructs encoding the split nucleobase editor. The nuclear localization signal controls nuclear import, which must occur for reconstituted nucleobase editor to associate with genomic DNA as a prerequisite for editing, and is a potential rate-limiting step in the process. This schematic shows that the NLS (and NLS optimization) is critical for the nucleobase editor to be imported into the nucleus. 
         FIG. 7  is a graph showing the results of base editing using different rAAV split nucleobase editor constructs containing different nuclear localization signals (NLS). 
         FIGS. 8A-8B  are graphs showing the editing of DNMT1 gene in dissociated mouse cortical neurons using an AAV encoded split nucleobase editor. 
         FIG. 9A-9B  are graphs showing the editing of DNMT1 gene in mouse Neuro-2a cell line using either an AAV encoded split nucleobase editor, or a lipid transfected DNA encoded nucleobase editor. 
     
    
    
     DEFINITIONS 
     As used herein and in the claims, the singular forms “a,” “an,” and “the” include the singular and the plural reference unless the context clearly indicates otherwise. Thus, for example, a reference to “an agent” includes a single agent and a plurality of such agents. 
     As used herein, the term “Cas9,” “Cas9 protein,” or “Cas9 nuclease” refers to an RNA-guided nuclease comprising a Cas9 protein (e.g., Cas9 nucleases from a variety of bacterial species), a fragment, a variant (e.g., a catalytically inactive Cas9 or a Cas9 nickase), or a fusion protein (e.g., a Cas9 fused to another protein domain) thereof. A Cas9 nuclease is also referred to sometimes as a casn1 nuclease or a CRISPR (clustered regularly interspaced short palindromic repeat)-associated nuclease. CRISPR is an adaptive immune system that provides protection against mobile genetic elements (viruses, transposable elements, and conjugative plasmids). CRISPR clusters contain spacers, sequences complementary to antecedent mobile elements, and target invading nucleic acids. CRISPR clusters are transcribed and processed into CRISPR RNA (crRNA). In type II CRISPR systems correct processing of pre-crRNA requires a trans-encoded small RNA (tracrRNA), endogenous ribonuclease 3 (rnc) and a Cas9 protein. The tracrRNA serves as a guide for ribonuclease 3-aided processing of pre-crRNA. Subsequently, Cas9/crRNA/tracrRNA endonucleolytically cleaves linear or circular dsDNA target complementary to the spacer. In nature, DNA-binding and cleavage typically requires protein and both RNAs. However, single guide RNAs (“sgRNA”, or simply “gNRA”) can be engineered so as to incorporate aspects of both the crRNA and tracrRNA into a single RNA species. Non-limiting examples of Cas9 proteins and their respective amino acid sequence are provided in Example 1. 
     A nuclease-inactive Cas9 protein may interchangeably be referred to as a “dCas9” protein (for nuclease-“dead” Cas9). Methods for generating a Cas9 protein (or a fragment thereof) having an inactive DNA cleavage domain are known (See, e.g., Jinek et al.,  Science.  337:816-821(2012); Qi et al., (2013)  Cell.  28; 152(5):1173-83, incorporated herein by reference). For example, the DNA cleavage domain of Cas9 is known to include two subdomains, the HNH nuclease subdomain and the RuvC1 subdomain. The HNH subdomain cleaves the strand complementary to the gRNA, whereas the RuvC1 subdomain cleaves the non-complementary strand. Mutations within these subdomains can silence the nuclease activity of Cas9. For example, the mutations D10A and H840A completely inactivate the nuclease activity of  S. pyogenes  Cas9 (Jinek et al.,  Science.  337:816-821(2012); Qi et al.,  Cell.  28; 152(5):1173-83 (2013). Additional suitable nuclease-inactive dCas9 domains will be apparent to those of skill in the art based on this disclosure and knowledge in the field, and are within the scope of this disclosure. Such additional exemplary suitable nuclease-inactive Cas9 domains include, but are not limited to, D10A/H840A, D10A/D839A/H840A, and D10A/D839A/H840A/N863A mutant domains (See, e.g., Prashant et al.,  Nature Biotechnology.  2013; 31(9):833-838, incorporated herein by reference). 
     In some embodiments, a Cas9 nickase is used as part of the nucleobase editor. A Cas9 nickase is able to cleave one strand of the double strand DNA. A Cas9 nickase may be generated by introducing an inactivating mutation into either the HNH domain or the RuvC1 domain. For example, an inactivating mutation (D10A) may be introduced in the RuvC1 domain of the  S. pyogenes  Cas9, while the HNH domain remains active, i.e., the residue at position 840 remains a histidine. Such Cas9 variants are able to generate a single-strand DNA break (nick) at a specific location based on the gRNA-defined target sequence. One skilled in the art is able to identify the catalytic residues in the RuvC1 and HNH domains of any known Cas9 proteins and introduce inactivating mutations to generate a corresponding dCas9 or nCas9. 
     A “split Cas9 protein” or “split Cas9” refers to a Cas9 protein that is provided as an N-terminal portion (also referred to as an N-terminal half) and a C-terminal portion (also referred to as a C-terminal half) encoded by two separate nucleotide sequences. The polypeptides corresponding to the N-terminal portion and the C-terminal portion of the Cas9 protein may be combined (joined) to form a complete Cas9 protein. A Cas9 protein is known to consist of a bi-lobed structure linked by a disordered linker (e.g., as described in Nishimasu et al.,  Cell, Volume  156, Issue 5, pp. 935-949, 2014, incorporated herein by reference). In some embodiments, the “split” occurs between the two lobes, generating two portions of a Cas9 protein, each containing one lobe. 
     An “intein” is a segment of a protein that is able to excise itself and join the remaining portions (the exteins) with a peptide bond in a process known as protein splicing. Inteins are also referred to as “protein introns.” The process of an intein excising itself and joining the remaining portions of the protein is herein termed “protein splicing” or “intein-mediated protein splicing.” In some embodiments, an intein of a precursor protein (an intein containing protein prior to intein-mediated protein splicing) comes from two genes. Such intein is referred to herein as a split intein. For example, in cyanobacteria, DnaE, the catalytic subunit α of DNA polymerase III, is encoded by two separate genes, dnaE-n and dnaE-c. The intein encoded by the dnaE-n gene is herein referred as “intein-N.” The intein encoded by the dnaE-c gene is herein referred as “intein-C.” 
     Other intein systems may also be used. For example, a synthetic intein based on the dnaE intein, the Cfa-N and Cfa-C intein pair, has been described (e.g., in Stevens et al., J Am Chem Soc. 2016 Feb. 24; 138(7):2162-5, incorporated herein by reference). Non-limiting examples of intein pairs that may be used in accordance with the present disclosure include: Cfa DnaE intein, Ssp GyrB intein, Ssp DnaX intein, Ter DnaE3 intein, Ter ThyX intein, Rma DnaB intein and Cne Prp8 intein (e.g., as described in U.S. Pat. No. 8,394,604, incorporated herein by reference. 
     Exemplary nucleotide and amino acid sequences of inteins are provided.

     Intein-N and intein-C may be fused to the N-terminal portion of the split Cas9 and the C-terminal portion of the split Cas9, respectively, for the joining of the N-terminal portion of the split Cas9 and the C-terminal portion of the split Cas9. For example, in some embodiments, an intein-N is fused to the C-terminus of the N-terminal portion of the split Cas9, i.e., to form a structure of N-[N-terminal portion of the split Cas9]-[intein-N]-C. In some embodiments, an intein-C is fused to the N-terminus of the C-terminal portion of the split Cas9, i.e., to form a structure of N-[intein-C]-[C-terminal portion of the split Cas9]-C. The mechanism of intein-mediated protein splicing for joining the proteins the inteins are fused to (e.g., split Cas9) is known in the art, e.g., as described in Shah et al.,  Chem Sci.  2014; 5(1):446-461, incorporated herein by reference. 
     Herein, a “nucleobase editor” refers to a protein that edits a nucleotide base. “Edit” refers to the conversion of one nucleobase to another (e.g., A to G, A to C, A to T, C to T, C to G, C to A, G to A, G to C, G to T, T to A, T to C, T to G). In some embodiments, a nucleobase editor is a macromolecule or macromolecular complex that results primarily (e.g., more than 80%, more than 85%, more than 90%, more than 95%, more than 99%, more than 99.9%, or 100%) in the conversion of a nucleobase in a polynucleic acid sequence into another nucleobase (i.e., a transition or transversion) using a combination of 1) a nucleotide-, nucleoside-, or nucleobase-modifying enzyme and 2) a nucleic acid binding protein that can be programmed to bind to a specific nucleic acid sequence. 
     In some embodiments, the nucleobase editor comprises a DNA binding domain (e.g., a programmable DNA binding domain such as a dCas9 or nCas9) that directs it to a target sequence. In some embodiments, the nucleobase editor comprises a nucleobase modifying enzyme fused to a programmable DNA binding domain (e.g., a dCas9 or nCas9). A “nucleobase modifying enzyme” is an enzyme that can modify a nucleobase and convert one nucleobase to another (e.g., a deaminase such as a cytosine deaminase or a adenosine deaminase). In some embodiments, the nucleobase editor may target cytosine (C) bases in a nucleic acid sequence and convert the C to thymine (T) base. In some embodiments, the C to T editing is carried out by a deaminase, e.g., a cytosine deaminase. Base editors that can carry out other types of base conversions (e.g., adenosine (A) to guanine (G), C to G) are also contemplated. 
     Nucleobase editors that convert a C to T, in some embodiments, comprise a cytosine deaminase. A “cytosine deaminase” refers to an enzyme that catalyzes the chemical reaction “cytosine+H 2 O→uracil+NH 3 ” or “5-methyl-cytosine+H 2 O→thymine+NH 3 .” As it may be apparent from the reaction formula, such chemical reactions result in a C to U/T nucleobase change. In the context of a gene, such a nucleotide change, or mutation, may in turn lead to an amino acid change in the protein, which may affect the protein&#39;s function, e.g., loss-of-function or gain-of-function. In some embodiments, the C to T nucleobase editor comprises a dCas9 or nCas9 fused to a cytosine deaminase. In some embodiments, the cytosine deaminase domain is fused to the N-terminus of the dCas9 or nCas9. In some embodiments, the nucleobase editor further comprises a domain that inhibits uracil glycosylase, and/or a nuclear localization signal. Such nucleobase editors have been described in the art, e.g., in U.S. Pat. No. 9,068,179, US Patent Application Publications US 2015/0166980, published Jun. 18, 2015; US 2015/0166981, published Jun. 18, 2015; US 2015/0166982, published Jun. 18, 2015; US 2015/0166984, published Jun. 18, 2015; and US2015/0165054, published Jun. 18, 2015; and US Provisional applications, U.S. Ser.

     In some embodiments, a nucleobase editor converts an A to G. In some embodiments, the nucleobase editor comprises an adenosine deaminase. An “adenosine deaminase” is an enzyme involved in purine metabolism. It is needed for the breakdown of adenosine from food and for the turnover of nucleic acids in tissues. Its primary function in humans is the development and maintenance of the immune system. An adenosine deaminase catalyzes hydrolytic deamination of adenosine (forming inosine, which base pairs as G) in the context of DNA. There are no known adenosine deaminases that act on DNA. Instead, known adenosine deaminase enzymes only act on RNA (tRNA or mRNA). Evolved deoxyadenosine deaminase enzymes that accept DNA substrates and deaminate dA to deoxyinosine and here use in adenosine nucleobase editos have been described, e.g., in US provisional application, U.S. Ser. No. 62/370,684, filed Aug. 3, 2016; US provisional application, U.S. Ser. No. 62/370,684, filed Feb. 3, 2017, US provisional application, U.S. Ser. No. 62/473,714, filed Mar. 20, 2017, and PCT Application PCT/US2017/045381, filed Aug. 3, 2017; each of which is incorporated herein by reference. Non-limiting examples of evolved adenosine deaminases that accept DNA as substrates are provided in Example 1. 
     In some embodiments, the adenosine deaminase is  E. coli  TadA (SEQ ID NO: 314). The possible mutations in ecTadA and constructs expressing nucleobase editors comprising the modified ecTadA are provided in Table 2. The sequences of exemplary EcTadA mutants and nucleotibase editors comprising such mutants are provided in Example 1.

     In some embodiments, a nucleobase editor converts a C to G. Such nucleobase editors are described in US provisional application, U.S. Ser. No. 62/470,175, filed Mar. 10, 2017, US provisional application, U.S. Ser. No. 62/470,175, filed Mar. 10, 2017 incorporated herein by reference. 
     Non-limiting, exemplary types of nucleobase editors (including C to T, A to G, and C to G nucleobase editors) and their respective sequences are provided in Example 1. In some embodiments, the nucleobase editor is a variant of the nucleobase editors described herein. For example, in some embodiments, the nucleobase editor is at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75% at least 80%, at least 85%, at least 90%, at least 95%, at least 96%, at least 97%, at least 98%, at least 99%, or at least 99.5% identical to a nucleobase editor described herein (exemplary sequences are provided in Example 1). In some embodiments, the nucleobase editor comprises an amino acid sequence that is shorter or longer in length (e.g., by no more than 30%, no more than 25%, no more than 20%, no more than 15%, no more than 10%, no more than 5%, no more than 1% longer or shorter) than any of the nucleobase editors provided herein. In some embodiments, the nucleobase editor comprises an amino acid sequence that is shorter or longer in length (e.g., by no more than 500 amino acids, no more than 450 amino acids, no more than 400 amino acids, no more than 350 amino acids, no more than 300 amino acids, no more than 250 amino acids, no more than 200 amino acids, no more than 200 amino acids, no more than 150 amino acids, no more than 100 amino acids, no more than 50 amino acids, no more than 10 amino acids, no more than 5 amino acids longer or shorter) than any of the nucleobase editors provided herein. 
     A “deaminase” refers to an enzyme that catalyzes the removal of an amine group from a molecule, or deamination, for example, through hydrolysis. In some embodiments, the deaminase is a cytidine deaminase, catalyzing the deamination of cytidine (C) to uridine (U), deoxycytidine (dC) to deoxyuridine (dU), or 5-methyl-cytidine to thymidine (T, 5-methyl-U), respectively. Subsequent DNA repair mechanisms ensure that a dU is replaced by T, as described in Komor et al. ( Nature , Programmable editing of a target base in genomic DNA without double-stranded DNA cleavage, 533, 420-424 (2016), which is incorporated herein by reference). In some embodiments, the deaminase is a cytosine deaminase, catalyzing and promoting the conversion of cytosine to uracil (e.g., in RNA) or thymine (e.g., in DNA). In some embodiments, the deaminase is an adenosine deaminase that converts an A to G. In some embodiments, the deaminase is a naturally-occurring deaminase from an organism, such as a human, chimpanzee, gorilla, monkey, cow, dog, rat, or mouse. In some embodiments, the deaminase is a variant of a naturally-occurring deaminase from an organism, and the variants do not occur in nature. For example, in some embodiments, the deaminase or deaminase domain is at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75% at least 80%, at least 85%, at least 90%, at least 95%, at least 96%, at least 97%, at least 98%, at least 99%, or at least 99.5% identical to a naturally-occurring deaminase from an organism. In some embodiments, the deaminase comprises an amino acid sequence that is shorter or longer in length (e.g., by no more than 30%, no more than 25%, no more than 20%, no more than 15%, no more than 10%, no more than 5%, no more than 1% longer or shorter) than any of the deaminases provided herein. In some embodiments, the deaminase comprises an amino acid sequence that is shorter or longer in length (e.g., by no more than 100 amino acids, no more than 90 amino acids, no more than 80 amino acids, no more than 70 amino acids, no more than 60 amino acids, no more than 50 amino acids, no more than 40 amino acids, no more than 30 amino acids, no more than 20 amino acids, no more than 10 amino acids, no more than 5 amino acids, no more than 2 amino acids, longer or shorter) than any of the deaminases provided herein. 
     A “split nucleobase editor” refers to a nucleobase editor that is provided as an N-terminal portion (also referred to as a N-terminal half) and a C-terminal portion (also referred to as a C-terminal half) encoded by two separate nucleic acids. The polypeptides corresponding to the N-terminal portion and the C-terminal portion of the nucleobase editor may be combined to form a complete nucleobase editor. In some embodiments, for a nucleobase editor that comprises a dCas9 or nCas9, the “split” is located in the dCas9 or nCas9 domain, at positions as described herein in the split Cas9. Accordingly, in some embodiments, the N-terminal portion of the nucleobase editor contains the N-terminal portion of the split Cas9, and the C-terminal portion of the nucleobase editor contains the C-terminal portion of the split Cas9. Similarly, intein-N or intein-C may be fused to the N-terminal portion or the C-terminal portion of the nucleobase editor, respectively, for the joining of the N- and C-terminal portions of the nucleobase editor to form a complete nucleobase editor. 
     Two proteins or protein domains are considered to be “fused” when a peptide bond is formed linking the two proteins or two protein domains. In some embodiments, a linker (e.g., a peptide linker) is present between the two proteins or two protein domains. The term “linker,” as used herein, refers to a chemical group or a molecule linking two molecules or moieties, e.g., two domains of a fusion protein, such as, for example, a nuclease-inactive Cas9 domain and a nucleic acid editing domain (e.g., a deaminase domain). Typically, the linker is positioned between, or flanked by, two groups, molecules, or other moieties and connected to each one via a covalent bond, thus connecting the two. In some embodiments, the linker is an amino acid or a plurality of amino acids (e.g., a peptide or protein). In some embodiments, the linker is an organic molecule, group, polymer, or chemical moiety. In some embodiments, the linker is 5-100 amino acids in length, for example, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 30-35, 35-40, 40-45, 45-50, 50-60, 60-70, 70-80, 80-90, 90-100, 100-150, or 150-200 amino acids in length. Longer or shorter links are also contemplated. 
     A “uracil glycosylase inhibitor (UGI)” refers to a protein that inhibits the activity of uracil-DNA glycosylase. Suitable UGI proteins for use in accordance with the present disclosure include, for example, those published in Wang et al.,  J. Biol. Chem.  264:1163-1171(1989); Lundquist et al.,  J. Biol. Chem.  272:21408-21419(1997); Ravishankar et al.,  Nucleic Acids Res.  26:4880-4887(1998); and Putnam et al.,  J. Mol. Biol.  287:331-346(1999), each of which is incorporated herein by reference. Non-limiting, exemplary proteins that may be used as a UGI of the present disclosure and their respective sequences are provided in Example 1. In some embodiments, the UGI is a variant of a naturally-occurring deaminase from an organism, and the variants do not occur in nature. For example, in some embodiments, the UGI is at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75% at least 80%, at least 85%, at least 90%, at least 95%, at least 96%, at least 97%, at least 98%, at least 99%, or at least 99.5% identical to a naturally-occurring UGI from an organism or any UGIs provided herein (e.g., in Example 1). In some embodiments, the UGI comprises an amino acid sequence that is shorter or longer in length (e.g., by no more than 30%, no more than 25%, no more than 20%, no more than 15%, no more than 10%, no more than 5%, no more than 1% longer or shorter) than any of the UGIs provided herein. In some embodiments, the UGI comprises an amino acid sequence that is shorter or longer in length (e.g., by no more than 20 amino acids, no more than 15 amino acids, no more than 10 amino acids, no more than 5 amino acids, no more than 2 amino acids longer or shorter) than any of the UGIs provided herein. 
     A gRNA is a component of the CRISPR/Cas system. A “gRNA” (guide ribonucleic acid) herein refers to a fusion of a CRISPR-targeting RNA (crRNA) and a trans-activation crRNA (tracrRNA), providing both targeting specificity and scaffolding/binding ability for Cas9 nuclease. A “crRNA” is a bacterial RNA that confers target specificity and requires tracrRNA to bind to Cas9. A “tracrRNA” is a bacterial RNA that links the crRNA to the Cas9 nuclease and typically can bind any crRNA. The sequence specificity of a Cas DNA-binding protein is determined by gRNAs, which have nucleotide base-pairing complementarity to target DNA sequences. The native gRNA comprises a 20 nucleotide (nt) Specificity Determining Sequence (SDS), which specifies the DNA sequence to be targeted, and is immediately followed by a 80 nt scaffold sequence, which associates the gRNA with Cas9. In some embodiments, an SDS of the present disclosure has a length of 15 to 100 nucleotides, or more. For example, an SDS may have a length of 15 to 90, 15 to 85, 15 to 80, 15 to 75, 15 to 70, 15 to 65, 15 to 60, 15 to 55, 15 to 50, 15 to 45, 15 to 40, 15 to 35, 15 to 30, or 15 to 20 nucleotides. In some embodiments, the SDS is 20 nucleotides long. For example, the SDS may be 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, or 25 nucleotides long. At least a portion of the target DNA sequence is complementary to the SDS of the gRNA. For Cas9 to successfully bind to the DNA target sequence, a region of the target sequence is complementary to the SDS of the gRNA sequence and is immediately followed by the correct protospacer adjacent motif (PAM) sequence (e.g., NGG for Cas9 and TTN, TTTN, or YTN for Cpf1). In some embodiments, an SDS is 100% complementary to its target sequence. In some embodiments, the SDS sequence is less than 100% complementary to its target sequence and is, thus, considered to be partially complementary to its target sequence. For example, a targeting sequence may be 99%, 98%, 97%, 96%, 95%, 94%, 93%, 92%, 91%, or 90% complementary to its target sequence. In some embodiments, the SDS of template DNA or target DNA may differ from a complementary region of a gRNA by 1, 2, 3, 4 or 5 nucleotides. 
     In addition to the SDS, the gRNA comprises a scaffold sequence (corresponding to the tracrRNA in the native CRISPR/Cas system) that is required for its association with Cas9 (referred to herein as the “gRNA handle”). In some embodiments, the gRNA comprises a structure 5′-[SDS]-[gRNA handle]-3′. In some embodiments, the scaffold sequence comprises the nucleotide sequence of 5′-guuuuagagcuagaaauagcaaguuaaaauaaaggcuaguc cguuaucaacuugaaaaaguggcaccgagucggugcuuuuu-3′ (SEQ ID NO: 358). Other non-limiting, suitable gRNA handle sequences that may be used in accordance with the present disclosure are listed in Table 1.

     In some embodiments, the guide RNA is about 15-120 nucleotides long and comprises a sequence of at least 10 contiguous nucleotides that is complementary to a target sequence. In some embodiments, the guide RNA is 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, or 120 nucleotides long. In some embodiments, the guide RNA comprises a sequence of 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 or more contiguous nucleotides that is complementary to a target sequence. Sequence complementarity refers to distinct interactions between adenine and thymine (DNA) or uracil (RNA), and between guanine and cytosine. 
     A “protospacer adjacent motif” (PAM) is typically a sequence of nucleotides located adjacent to (e.g., within 10, 9, 8, 7, 6, 5, 4, 3, 3, or 1 nucleotide(s) of a target sequence). A PAM sequence is “immediately adjacent to” a target sequence if the PAM sequence is contiguous with the target sequence (that is, if there are no nucleotides located between the PAM sequence and the target sequence). In some embodiments, a PAM sequence is a wild-type PAM sequence. Examples of PAM sequences include, without limitation, NGG, NGR, NNGRR(T/N), NNNNGATT, NNAGAAW, NGGAG, NAAAAC, AWG, and CC. In some embodiments, a PAM sequence is obtained from  Streptococcus pyogenes  (e.g., NGG or NGR). In some embodiments, a PAM sequence is obtained from  Staphylococcus aureus  (e.g., NNGRR(T/N)). In some embodiments, a PAM sequence is obtained from  Neisseria meningitidis  (e.g., NNNNGATT). In some embodiments, a PAM sequence is obtained from  Streptococcus thermophilus  (e.g., NNAGAAW or NGGAG). In some embodiments, a PAM sequence is obtained from  Treponema denticola  (e.g., NAAAAC). In some embodiments, a PAM sequence is obtained from  Escherichia coli  (e.g., AWG). In some embodiments, a PAM sequence is obtained from  Pseudomonas auruginosa  (e.g., CC). Other PAM sequences are contemplated. A PAM sequence is typically located downstream (i.e., 3′) from the target sequence, although in some embodiments a PAM sequence may be located upstream (i.e., 5′) from the target sequence. 
     A “nuclear localization signal” or “NLS” refers to as an amino acid sequence that “tags” a protein for import into the cell nucleus by nuclear transport. Typically, this signal consists of one or more short sequences of positively charged lysines or arginines exposed on the protein surface. One or more NLS may be added to the N- or C-terminus of a protein, or internally (e.g., between two protein domains). For example, one or more NLS may be added to the N- or C-terminus of a nucleobase editor, or between the Cas9 and the deaminase in a nucleobase editor. In some embodiments, 1, 2, 3, 4, 5, or more NLS may be added. Nuclear localization sequences are known in the art and would be apparent to the skilled artisan. For example, NLS sequences are described in Plank et al., PCT/EP2000/011690, filed Nov. 23, 2000, the contents of which are incorporated herein by reference for its disclosure of exemplary nuclear localization sequences. In some embodiments, a NLS comprises the amino acid sequence PKKKRKV (SEQ ID NO: 373) or MDSLLMNRRKFLYQFKNVRWAKGRRETYLC (SEQ ID NO: 374). In some embodiments, a linker is inserted between the Cas9 and the deaminase. 
     An NLS can be classified as monopartite or bipartite. A non-limiting example of a monopartite NLS is the sequence PKKKRKV (SEQ ID NO: 373) in the SV40 Large T-antigen. A bipartite NLS typically contains two clusters of basic amino acids, separated by a spacer of about 10 amino acids. One non-limiting example of a bipartite NLS is the NLS of nucleoplasmin, KR PAATKKAGQ AKKKK (spacer underlined) (SEQ ID NO: 344). In some embodiments, the NLS used in accordance with the present disclosure is the NLS of nucleoplasmin comprising the amino acid sequence of KRPAATKKAGQAKKKK (SEQ ID NO: 344). Other bipartite NLSs that may be used in accordance with the present disclosure include, without limitation: SV40 bipartite NLS (KRTADGSEFESPKKKRKV (SEQ ID NO: 375), e.g., as described in Hodel et al., J Biol Chem. 2001 Jan. 12; 276(2):1317-25, incorporated herein by reference); Kanadaptin bipartite NLS (KKTELQTTNAENKTKKL (SEQ ID NO: 345), e.g., as described in Hubner et al., Biochem J. 2002 Jan. 15; 361(Pt 2):287-96, incorporated herein by reference); influenza A nucleoprotein bipartite NLS (KRGINDRNFWRGENGRKTR (SEQ ID NO: 346), e.g., as described in Ketha et al., BMC Cell Biology. 2008; 9:22, incorporated herein by reference); and ZO-2 bipartite NLS (RKSGKIAAIVVKRPRK (SEQ ID NO: 347), e.g., as described in Quiros et al., Nusrat A, ed. Molecular Biology of the Cell. 2013; 24(16):2528-2543, incorporated herein by reference). 
     The nucleotide sequence encoding an NLS is “operably linked” to the nucleotide sequence encoding a protein to which the NLS is fused (e.g., a Cas9 or a nucleobase editor) when two coding sequences are “in-frame with each other” and are translated as a single polypeptide fusing two sequences. 
     Nucleic acids of the present disclosure may include one or more genetic elements. A “genetic element” refers to a particular nucleotide sequence that has a role in nucleic acid expression (e.g., promoter, enhancer, terminator) or encodes a discrete product of an engineered nucleic acid (e.g., a nucleotide sequence encoding a guide RNA, a protein and/or an RNA interference molecule). 
     A “promoter” refers to a control region of a nucleic acid sequence at which initiation and rate of transcription of the remainder of a nucleic acid sequence are controlled. A promoter may also contain sub-regions at which regulatory proteins and molecules may bind, such as RNA polymerase and other transcription factors. Promoters may be constitutive, inducible, activatable, repressible, tissue-specific, or any combination thereof. A promoter drives expression or drives transcription of the nucleic acid sequence that it regulates. Herein, a promoter is considered to be “operably linked” when it is in a correct functional location and orientation in relation to a nucleic acid sequence it regulates to control (“drive”) transcriptional initiation and/or expression of that sequence. 
     A promoter may be one naturally associated with a gene or sequence, as may be obtained by isolating the 5′ non-coding sequences located upstream of the coding segment of a given gene or sequence. Such a promoter is referred to as an “endogenous promoter.” In some embodiments, a coding nucleic acid sequence may be positioned under the control of a recombinant or heterologous promoter, which refers to a promoter that is not normally associated with the encoded sequence in its natural environment. Such promoters may include promoters of other genes; promoters isolated from any other cell; and synthetic promoters or enhancers that are not “naturally occurring” such as, for example, those that contain different elements of different transcriptional regulatory regions and/or mutations that alter expression through methods of genetic engineering that are known in the art. In addition to producing nucleic acid sequences of promoters and enhancers synthetically, sequences may be produced using recombinant cloning and/or nucleic acid amplification technology, including polymerase chain reaction (PCR). 
     In some embodiments, promoters used in accordance with the present disclosure are “inducible promoters,” which are promoters that are characterized by regulating (e.g., initiating or activating) transcriptional activity when in the presence of, influenced by or contacted by an inducer signal. An inducer signal may be endogenous or a normally exogenous condition (e.g., light), compound (e.g., chemical or non-chemical compound) or protein that contacts an inducible promoter in such a way as to be active in regulating transcriptional activity from the inducible promoter. Thus, a “signal that regulates transcription” of a nucleic acid refers to an inducer signal that acts on an inducible promoter. A signal that regulates transcription may activate or inactivate transcription, depending on the regulatory system used. Activation of transcription may involve directly acting on a promoter to drive transcription or indirectly acting on a promoter by inactivation a repressor that is preventing the promoter from driving transcription. Conversely, deactivation of transcription may involve directly acting on a promoter to prevent transcription or indirectly acting on a promoter by activating a repressor that then acts on the promoter. 
     A “transcriptional terminator” is a nucleic acid sequence that causes transcription to stop. A transcriptional terminator may be unidirectional or bidirectional. It is comprised of a DNA sequence involved in specific termination of an RNA transcript by an RNA polymerase. A transcriptional terminator sequence prevents transcriptional activation of downstream nucleic acid sequences by upstream promoters. A transcriptional terminator may be necessary in vivo to achieve desirable expression levels or to avoid transcription of certain sequences. A transcriptional terminator is considered to be “operably linked to” a nucleotide sequence when it is able to terminate the transcription of the sequence it is linked to. 
     The most commonly used type of terminator is a forward terminator. When placed downstream of a nucleic acid sequence that is usually transcribed, a forward transcriptional terminator will cause transcription to abort. In some embodiments, bidirectional transcriptional terminators are provided, which usually cause transcription to terminate on both the forward and reverse strand. In some embodiments, reverse transcriptional terminators are provided, which usually terminate transcription on the reverse strand only. 
     In prokaryotic systems, terminators usually fall into two categories (1) rho-independent terminators and (2) rho-dependent terminators. Rho-independent terminators are generally composed of palindromic sequence that forms a stem loop rich in G-C base pairs followed by several T bases. Without wishing to be bound by theory, the conventional model of transcriptional termination is that the stem loop causes RNA polymerase to pause, and transcription of the poly-A tail causes the RNA:DNA duplex to unwind and dissociate from RNA polymerase. 
     In eukaryotic systems, the terminator region may comprise specific DNA sequences that permit site-specific cleavage of the new transcript so as to expose a polyadenylation site. This signals a specialized endogenous polymerase to add a stretch of about 200 A residues (polyA) to the 3′ end of the transcript. RNA molecules modified with this polyA tail appear to more stable and are translated more efficiently. Thus, in some embodiments involving eukaryotes, a terminator may comprise a signal for the cleavage of the RNA. In some embodiments, the terminator signal promotes polyadenylation of the message. The terminator and/or polyadenylation site elements may serve to enhance output nucleic acid levels and/or to minimize read through between nucleic acids. 
     Terminators for use in accordance with the present disclosure include any terminator of transcription described herein or known to one of ordinary skill in the art. Examples of terminators include, without limitation, the termination sequences of genes such as, for example, the bovine growth hormone terminator, and viral termination sequences such as, for example, the SV40 terminator, spy, yejM, secG-leuU, thrLABC, rrnB T1, hisLGDCBHAFI, metZWV, rrnC, xapR, aspA and arcA terminator. In some embodiments, the termination signal may be a sequence that cannot be transcribed or translated, such as those resulting from a sequence truncation.

     An “adeno-associated virus” or “AAV” is a virus which infects humans and some other primate species. The wild-type AAV genome is a single-stranded deoxyribonucleic acid (ssDNA), either positive- or negative-sensed. The genome comprises two inverted terminal repeats (ITRs), one at each end of the DNA strand, and two open reading frames (ORFs): rep and cap between the ITRs. The rep ORF comprises four overlapping genes encoding Rep proteins required for the AAV life cycle. The cap ORF comprises overlapping genes encoding capsid proteins: VP1, VP2 and VP3, which interact together to form the viral capsid. VP1, VP2 and VP3 are translated from one mRNA transcript, which can be spliced in two different manners: either a longer or shorter intron can be excised resulting in the formation of two isoforms of mRNAs: a ˜2.3 kb- and a ˜2.6 kb-long mRNA isoform. The capsid forms a supramolecular assembly of approximately 60 individual capsid protein subunits into a non-enveloped, T-1 icosahedral lattice capable of protecting the AAV genome. The mature capsid is composed of VP1, VP2, and VP3 (molecular masses of approximately 87, 73, and 62 kDa respectively) in a ratio of about 1:1:10. 
     rAAV particles may comprise a nucleic acid vector (e.g., a recombinant genome), which may comprise at a minimum: (a) one or more heterologous nucleic acid regions comprising a sequence encoding a protein or polypeptide of interest (e.g., a split Cas9 or split nucleobase) or an RNA of interest (e.g., a gRNA), or one or more nucleic acid regions comprising a sequence encoding a Rep protein; and (b) one or more regions comprising inverted terminal repeat (ITR) sequences (e.g., wild-type ITR sequences or engineered ITR sequences) flanking the one or more nucleic acid regions (e.g., heterologous nucleic acid regions). In some embodiments, the nucleic acid vector is between 4 kb and 5 kb in size (e.g., 4.2 to 4.7 kb in size). In some embodiments, the nucleic acid vector further comprises a region encoding a Rep protein. In some embodiments, the nucleic acid vector is circular. In some embodiments, the nucleic acid vector is single-stranded. In some embodiments, the nucleic acid vector is double-stranded. In some embodiments, a double-stranded nucleic acid vector may be, for example, a self-complimentary vector that contains a region of the nucleic acid vector that is complementary to another region of the nucleic acid vector, initiating the formation of the double-strandedness of the nucleic acid vector. 
     The terms “nucleic acid,” and “polynucleotide,” as used herein, refer to a compound comprising a nucleobase and an acidic moiety, e.g., a nucleotide, or a polymer of nucleotides. Typically, polymeric nucleic acids, e.g., nucleic acid molecules comprising three or more nucleotides are linear molecules, in which adjacent nucleotides are linked to each other via a phosphodiester linkage. In some embodiments, “nucleic acid” refers to individual nucleic acid residues (e.g. nucleotides and/or nucleosides). In some embodiments, “nucleic acid” refers to an oligonucleotide chain comprising three or more individual nucleotide residues. As used herein, the terms “oligonucleotide” and “polynucleotide” can be used interchangeably to refer to a polymer of nucleotides (e.g., a string of at least three nucleotides). In some embodiments, “nucleic acid” encompasses RNA as well as single and/or double-stranded DNA. Nucleic acids may be naturally occurring, for example, in the context of a genome, a transcript, an mRNA, tRNA, rRNA, siRNA, snRNA, a plasmid, cosmid, chromosome, chromatid, or other naturally occurring nucleic acid molecule. On the other hand, a nucleic acid molecule may be a non-naturally occurring molecule, e.g., a recombinant DNA or RNA, an artificial chromosome, an engineered genome (e.g., an engineered viral vector), an engineered vector, or fragment thereof, or a synthetic DNA, RNA, or DNA/RNA hybrid, optionally including non-naturally occurring nucleotides or nucleosides. Furthermore, the terms “nucleic acid,” “DNA,” “RNA,” and/or similar terms include nucleic acid analogs, e.g., analogs having other than a phosphodiester backbone. Nucleic acids can be purified from natural sources, produced using recombinant expression systems and optionally purified, chemically synthesized, etc. Where appropriate, e.g., in the case of chemically synthesized molecules, nucleic acids can comprise nucleoside analogs such as analogs having chemically modified bases or sugars, and backbone modifications. A nucleic acid sequence is presented in the 5′ to 3′ direction unless otherwise indicated. In some embodiments, a nucleic acid is or comprises natural nucleosides (e.g. adenosine, thymidine, guanosine, cytidine, uridine, deoxyadenosine, deoxythymidine, deoxyguanosine, and deoxycytidine); nucleoside analogs (e.g., 2-aminoadenosine, 2-thiothymidine, inosine, pyrrolo-pyrimidine, 3-methyl adenosine, 5-methylcytidine, 2-aminoadenosine, C5-bromouridine, C5-fluorouridine, C5-iodouridine, C5-propynyl-uridine, C5-propynyl-cytidine, C5-methylcytidine, 2-aminoadenosine, 7-deazaadenosine, 7-deazaguanosine, 8-oxoadenosine, 8-oxoguanosine, O(6)-methylguanine, and 2-thiocytidine); chemically modified bases; biologically modified bases (e.g., methylated bases); intercalated bases; modified sugars (e.g., 2′-fluororibose, ribose, 2′-deoxyribose, arabinose, and hexose); and/or modified phosphate groups (e.g., phosphorothioates and 5′-N-phosphoramidite linkages). 
     The terms “protein,” “peptide,” and “polypeptide” are used interchangeably herein, and refer to a polymer of amino acid residues linked together by peptide (amide) bonds. The terms refer to a protein, peptide, or polypeptide of any size, structure, or function. Typically, a protein, peptide, or polypeptide will be at least three amino acids long. A protein, peptide, or polypeptide may refer to an individual protein or a collection of proteins. One or more of the amino acids in a protein, peptide, or polypeptide may be modified, for example, by the addition of a chemical entity such as a carbohydrate group, a hydroxyl group, a phosphate group, a farnesyl group, an isofarnesyl group, a fatty acid group, a linker for conjugation, functionalization, or other modification, etc. A protein, peptide, or polypeptide may also be a single molecule or may be a multi-molecular complex. A protein, peptide, or polypeptide may be just a fragment of a naturally occurring protein or peptide. A protein, peptide, or polypeptide may be naturally occurring, recombinant, or synthetic, or any combination thereof. The term “fusion protein” as used herein refers to a hybrid polypeptide which comprises protein domains from at least two different proteins. One protein may be located at the amino-terminal (N-terminal) portion of the fusion protein or at the carboxy-terminal (C-terminal) protein thus forming an “amino-terminal fusion protein” or a “carboxy-terminal fusion protein,” respectively. A protein may comprise different domains, for example, a nucleic acid binding domain (e.g., the gRNA binding domain of Cas9 that directs the binding of the protein to a target site) and a nucleic acid cleavage domain or a catalytic domain of a nucleic-acid editing protein. In some embodiments, a protein is in a complex with, or is in association with, a nucleic acid, e.g., RNA or DNA. Any of the proteins provided herein may be produced by any method known in the art. For example, the proteins provided herein may be produced via recombinant protein expression and purification, which is especially suited for fusion proteins comprising a peptide linker. Methods for recombinant protein expression and purification are well known, and include those described by Green and Sambrook,  Molecular Cloning: A Laboratory Manual  (4 th  ed., Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y. (2012)), which are incorporated herein by reference. 
     The term “subject,” as used herein, refers to an individual organism, for example, an individual mammal. In some embodiments, the subject is a human. In some embodiments, the subject is a non-human mammal. In some embodiments, the subject is a non-human primate. In some embodiments, the subject is a rodent (e.g., mouse, rat). In some embodiments, the subject is a domesticated animal. In some embodiments, the subject is a sheep, a goat, a cow, a cat, or a dog. In some embodiments, the subject is a research animal. In some embodiments, the subject is genetically engineered, e.g., a genetically engineered non-human subject. The subject may be of either sex and at any stage of development. 
     The term “recombinant” as used herein in the context of proteins or nucleic acids refers to proteins or nucleic acids that do not occur in nature, but are the product of human engineering. For example, in some embodiments, a recombinant protein or nucleic acid molecule comprises an amino acid or nucleotide sequence that comprises at least one, at least two, at least three, at least four, at least five, at least six, or at least seven mutations as compared to any naturally occurring sequence. The fusion proteins (e.g., base editors) described herein are made recombinantly. Recombinant technology is familiar to those skilled in the art. 
     The term “pharmaceutically-acceptable carrier” means a pharmaceutically-acceptable material, composition or vehicle, such as a liquid or solid filler, diluent, excipient, manufacturing aid (e.g., lubricant, talc magnesium, calcium or zinc stearate, or steric acid), or solvent encapsulating material, involved in carrying or transporting the compound from one site (e.g., the delivery site) of the body, to another site (e.g., organ, tissue or portion of the body). A pharmaceutically acceptable carrier is “acceptable” in the sense of being compatible with the other ingredients of the formulation and not injurious to the tissue of the subject (e.g., physiologically compatible, sterile, physiologic pH, etc.). 
     “A therapeutically effective amount” as used herein refers to the amount of each therapeutic agent (e.g., nucleobase editor, rAAV) described in the present disclosure required to confer therapeutic effect on the subject, either alone or in combination with one or more other therapeutic agents. Effective amounts vary, as recognized by those skilled in the art, depending on the particular condition being treated, the severity of the condition, the individual subject parameters including age, physical condition, size, gender, and weight, the duration of the treatment, the nature of concurrent therapy (if any), the specific route of administration and like factors within the knowledge and expertise of the health practitioner. These factors are well known to those of ordinary skill in the art and can be addressed with no more than routine experimentation. It is generally preferred that a maximum dose of the individual components or combinations thereof be used, that is, the highest safe dose according to sound medical judgment. It will be understood by those of ordinary skill in the art, however, that a subject may insist upon a lower dose or tolerable dose for medical reasons, psychological reasons or for virtually any other reasons. Empirical considerations, such as the half-life, generally will contribute to the determination of the dosage. For example, therapeutic agents that are compatible with the human immune system, such as polypeptides comprising regions from humanized antibodies or fully human antibodies, may be used to prolong half-life of the polypeptide and to prevent the polypeptide being attacked by the host&#39;s immune system. 
     “A subject in need thereof” refers to an individual who has a disease, a sign and/or symptom of a disease, or a predisposition toward a disease, with the purpose to cure, heal, alleviate, relieve, alter, remedy, ameliorate, improve, or affect the disease, the symptom of the disease, or the predisposition toward the disease. In some embodiments, the subject is a mammal. In some embodiments, the subject is a non-human primate. In some embodiments, the subject is human. In some embodiments, the mammal is a rodent. In some embodiments, the rodent is a mouse. In some embodiments, the rodent is a rat. In some embodiments, the mammal is a companion animal. A “companion animal” refers to pets and other domestic animals. Non-limiting examples of companion animals include dogs and cats; livestock, such as horses, cattle, pigs, sheep, goats, and chickens; and other animals, such as mice, rats, guinea pigs, and hamsters. 
     The terms “treatment,” “treat,” and “treating,” refer to a clinical intervention aimed to reverse, alleviate, delay the onset of, or inhibit the progress of a disease or disorder, or one or more symptoms thereof, as described herein. As used herein, the terms “treatment,” “treat,” and “treating” refer to a clinical intervention aimed to reverse, alleviate, delay the onset of, or inhibit the progress of a disease or disorder, or one or more symptoms thereof, as described herein. In some embodiments, treatment may be administered after one or more symptoms have developed and/or after a disease has been diagnosed. In other embodiments, treatment may be administered in the absence of symptoms, e.g., to prevent or delay onset of a symptom or inhibit onset or progression of a disease. For example, treatment may be administered to a susceptible individual prior to the onset of symptoms (e.g., in light of a history of symptoms and/or in light of genetic or other susceptibility factors). Treatment may also be continued after symptoms have resolved, for example, to prevent or delay their recurrence. 
     DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS 
     Provided herein, are compositions (e.g., vectors, recombinant viruses) and kits comprising nucleic acids encoding split Cas9 proteins or nucleobase editors, and methods of delivering a nucleobase editor or a Cas9 protein into a cell using such nucleic acids. The N-terminal portion and C-terminal portion of a nucleobase editor or a Cas9 protein are encoded on separate nucleic acids and delivered into a cell, e.g., a via recombinant adeno-associated virus (rAAV particles) delivery. The polypeptides corresponding to the N-terminal portion and C-terminal portions of the nucleobase editor or Cas9 protein may be joined to form a complete nucleobase editor or Cas9 protein, e.g., via intein-mediated protein splicing. 
     Accordingly, some aspects of the present disclosure relate to compositions comprising (i) a first nucleotide sequence encoding an N-terminal portion of a Cas9 protein fused at its C-terminus to an intein-N; and (ii) a second nucleotide sequence encoding an intein-C fused to the N-terminus of a C-terminal portion of the Cas9 protein, wherein the first nucleotide sequence or second nucleotide sequence is operably linked to a nucleotide sequence encoding at least one bipartite nuclear localization signal (NLS). 
     The Cas9 protein encoded by the first and second nucleotide sequence is herein referred as a “split Cas9.” The Cas9 protein is known to have a N-terminal lobe and a C-terminal lobe linked by a disordered linker (e.g., as described in Nishimasu et al., Cell, Volume 156, Issue 5, pp. 935-949, 2014, incorporated herein by reference). In some embodiments, the N-terminal portion of the split Cas9 protein comprises the N-terminal lobe of a Cas9 protein. In some embodiments, the C-terminal portion of the split Cas9 comprises the C-terminal lobe of a Cas9 protein. In some embodiments, the N-terminal portion of the split Cas9 comprises a portion of any one of SEQ ID NO: 1-275 and 394-397 that corresponds to amino acids 1-(550-650) in SEQ ID NO: 1. “1-(550-650)” means starting from amino acid 1 and ending anywhere between amino acid 550-650 (inclusive). For example, the N-terminal portion of the split Cas9 may comprise a portion of any one of SEQ ID NOs: 1-275 and 394-397 that corresponds to amino acids 1-550, 1-551, 1-552, 1-553, 1-554, 1-555, 1-556, 1-557, 1-558, 1-559, 1-560, 1-561, 1-562, 1-563, 1-564, 1-565, 1-566, 1-567, 1-568, 1-569, 1-570, 1-571, 1-572, 1-573, 1-574, 1-575, 1-576, 1-577, 1-578, 1-579, 1-580, 1-581, 1-582, 1-583, 1-584, 1-585, 1-586, 1-587, 1-588, 1-589, 1-590, 1-591, 1-592, 1-593, 1-594, 1-595, 1-596, 1-597, 1-598, 1-599, 1-600, 1-601, 1-602, 1-603, 1-604, 1-605, 1-606, 1-607, 1-608, 1-609, 1-610, 1-611, 1-612, 1-613, 1-614, 1-615, 1-616, 1-617, 1-618, 1-619, 1-620, 1-621, 1-622, 1-623, 1-624, 1-625, 1-626, 1-627, 1-628, 1-629, 1-630, 1-631, 1-632, 1-633, 1-634, 1-635, 1-636, 1-637, 1-638, 1-639, 1-640, 1-641, 1-642, 1-643, 1-644, 1-645, 1-646, 1-647, 1-648, 1-649, or 1-650 in SEQ ID NO: 1. In some embodiments, the N-terminal portion of the split Cas9 protein comprises a portion of any one of SEQ ID NOs: 1-275 and 394-397 that corresponds to amino acids 1-573 or 1-637 of SEQ ID NO: 1. 
     The C-terminal portion of the split Cas9 can be joined with the N-terminal portion of the split Cas9 to form a complete Cas9 protein. In some embodiments, the C-terminal portion of the Cas9 protein starts from where the N-terminal portion of the Cas9 protein ends. As such, in some embodiments, the C-terminal portion of the split Cas9 comprises a portion of any one of SEQ ID NO: 1-275 and 394-397 that corresponds to amino acids (551-651)-1368 of SEQ ID NO: 1. “(551-651)-1368” means starting at an amino acid between amino acids 551-651 (inclusive) and ending at amino acid 1368. For example, the C-terminal portion of the split Cas9 may comprise a portion of any one of SEQ ID NO: 1-275 and 394-397 that corresponds to amino acid 551-1368, 552-1368, 553-1368, 554-1368, 555-1368, 556-1368, 557-1368, 558-1368, 559-1368, 560-1368, 561-1368, 562-1368, 563-1368, 564-1368, 565-1368, 566-1368, 567-1368, 568-1368, 569-1368, 570-1368, 571-1368, 572-1368, 573-1368, 574-1368, 575-1368, 576-1368, 577-1368, 578-1368, 579-1368, 580-1368, 581-1368, 582-1368, 583-1368, 584-1368, 585-1368, 586-1368, 587-1368, 588-1368, 589-1368, 590-1368, 591-1368, 592-1368, 593-1368, 594-1368, 595-1368, 596-1368, 597-1368, 598-1368, 599-1368, 600-1368, 601-1368, 602-1368, 603-1368, 604-1368, 605-1368, 606-1368, 607-1368, 608-1368, 609-1368, 610-1368, 611-1368, 612-1368, 613-1368, 614-1368, 615-1368, 616-1368, 617-1368, 618-1368, 619-1368, 620-1368, 621-1368, 622-1368, 623-1368, 624-1368, 625-1368, 626-1368, 627-1368, 628-1368, 629-1368, 630-1368, 631-1368, 632-1368, 633-1368, 634-1368, 635-1368, 636-1368, 637-1368, 638-1368, 639-1368, 640-1368, 641-1368, 642-1368, 643-1368, 644-1368, 645-1368, 646-1368, 647-1368, 648-1368, 649-1368, 650-1368, or 651-1368 of SEQ ID NO: 1.

     Recombinant Adeno-Associated Virus (rAAV) 
     Some aspects of the present disclosure relate to using recombinant adeno-associated virus vectors for the delivery of a split Cas9 protein or a split nucleobase editor into a cell. The N-terminal portion of the Cas9 protein or the nucleobase editor and the C-terminal portion of the Cas9 protein or the nucleobase editor are delivered by separate rAAV vectors or particles into the same cell, since the full-length Cas9 protein or nucleobase editors exceeds the packaging limit of rAAV (˜4.9 kb). 
     As such, in some embodiments, a composition for delivering the split Cas9 protein or split nucleobase editor into a cell (e.g., a mammalian cell, a human cell) is provided. In some embodiments, the composition of the present disclosure comprises: (i) a first recombinant adeno-associated virus (rAAV) particle comprising a first nucleotide sequence encoding a N-terminal portion of a Cas9 protein or nucleobase editor fused at its C-terminus to an intein-N; and (ii) a second recombinant adeno-associated virus (rAAV) particle comprising a second nucleotide sequence encoding an intein-C fused to the N-terminus of a C-terminal portion of the Cas9 protein or nucleobase editor. The rAAV particles of the present disclosure comprise a rAAV vector (i.e., a recombinant genome of the rAAV) encapsidated in the viral capsid proteins. 
     In some embodiments, the rAAV vector comprises: (1) a heterologous nucleic acid region comprising the first or second nucleotide sequence encoding the N-terminal portion or C-terminal portion of a split Cas9 protein or a split nucleobase editor in any form as described herein, (2) one or more nucleotide sequences comprising a sequence that facilitates expression of the heterologous nucleic acid region (e.g., a promoter), and (3) one or more nucleic acid regions comprising a sequence that facilitate integration of the heterologous nucleic acid region (optionally with the one or more nucleic acid regions comprising a sequence that facilitates expression) into the genome of a cell. In some embodiments, viral sequences that facilitate integration comprise Inverted Terminal Repeat (ITR) sequences. In some embodiments, the first or second nucleotide sequence encoding the N-terminal portion or C-terminal portion of a split Cas9 protein or a split nucleobase editor is flanked on each side by an ITR sequence. In some embodiments, the nucleic acid vector further comprises a region encoding an AAV Rep protein as described herein, either contained within the region flanked by ITRs or outside the region. The ITR sequences can be derived from any AAV serotype (e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10) or can be derived from more than one serotype. In some embodiments, the ITR sequences are derived from AAV2 or AAV6. 
     ITR sequences and plasmids containing ITR sequences are known in the art and commercially available (see, e.g., products and services available from Vector Biolabs, Philadelphia, Pa.; Cellbiolabs, San Diego, Calif.; Agilent Technologies, Santa Clara, Ca; and Addgene, Cambridge, Mass.; and Gene delivery to skeletal muscle results in sustained expression and systemic delivery of a therapeutic protein.

     In some embodiments, the rAAV vector of the present disclosure comprises one or more regulatory elements to control the expression of the heterologous nucleic acid region (e.g., promoters, transcriptional terminators, and/or other regulatory elements). In some embodiments, the first and/or second nucleotide sequence is operably linked to one or more (e.g., 1, 2, 3, 4, 5, or more) transcriptional terminators. Non-limiting examples of transcriptional terminators that may be used in accordance with the present disclosure include transcription terminators of the bovine growth hormone gene (bGH), human growth hormone gene (hGH), SV40, CW3, ϕ, or combinations thereof. The efficiencies of several transcriptional terminators have been tested to determine their respective effects in the expression level of the split Cas9 protein or the split nucleobase editor (e.g., see  FIG. 4 ). In some embodiments, the transcriptional terminator used in the present disclosure is a bGH transcriptional terminator. In some embodiments, the rAAV vector further comprises a Woodchuck Hepatitis Virus Posttranscriptional Regulatory Element (WPRE). In some embodiments, the WPRE is inserted 5′ of the transcriptional terminator. 
     In some embodiments, the composition comprising the rAAV particle (in any form contemplated herein) further comprises a pharmaceutically acceptable carrier. In some embodiments, the composition is formulated in appropriate pharmaceutical vehicles for administration to human or animal subjects. 
     Some examples of materials which can serve as pharmaceutically-acceptable carriers include: (1) sugars, such as lactose, glucose and sucrose; (2) starches, such as corn starch and potato starch; (3) cellulose, and its derivatives, such as sodium carboxymethyl cellulose, methylcellulose, ethyl cellulose, microcrystalline cellulose and cellulose acetate; (4) powdered tragacanth; (5) malt; (6) gelatin; (7) lubricating agents, such as magnesium stearate, sodium lauryl sulfate and talc; (8) excipients, such as cocoa butter and suppository waxes; (9) oils, such as peanut oil, cottonseed oil, safflower oil, sesame oil, olive oil, corn oil and soybean oil; (10) glycols, such as propylene glycol; (11) polyols, such as glycerin, sorbitol, mannitol and polyethylene glycol (PEG); (12) esters, such as ethyl oleate and ethyl laurate; (13) agar; (14) buffering agents, such as magnesium hydroxide and aluminum hydroxide; (15) alginic acid; (16) pyrogen-free water; (17) isotonic saline; (18) Ringer&#39;s solution; (19) ethyl alcohol; (20) pH buffered solutions; (21) polyesters, polycarbonates and/or polyanhydrides; (22) bulking agents, such as polypeptides and amino acids (23) serum component, such as serum albumin, HDL and LDL; (22) C2-C12 alcohols, such as ethanol; and (23) other non-toxic compatible substances employed in pharmaceutical formulations.

The terms such as “excipient”, “carrier”, “pharmaceutically acceptable carrier” or the like are used interchangeably herein. 
     Methods of Use 
     Other aspects of the present disclosure provide methods of delivering the split Cas9 protein or the split nucleobase editor into a cell to form a complete and functional Cas9 protein or nucleobase editor. For example, in some embodiments, a cell is contacted with a composition described herein (e.g., compositions comprising nucleotide sequences encoding the split Cas9 or the split nucleobase editor or AAV particles containing nucleic acid vectors comprising such nucleotide sequences). In some embodiments, the contacting results in the delivery of such nucleotide sequences into a cell, wherein the N-terminal portion of the Cas9 protein or the nucleobase editor and the C-terminal portion of the Cas9 protein or the nucleobase editor are expressed in the cell and are joined to form a complete Cas9 protein or a complete nucleobase editor. 
     The split Cas9 protein or split nucleobase editor delivered using the methods described herein preferably have comparable activity compared to the original Cas9 protein or nucleobase editor (i.e., unsplit protein delivered to a cell or expressed in a cell as a whole). For example, the split Cas9 protein or split nucleobase editor retains at least 50% (e.g., at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, at least 95%, at least 98%, at least 99%, or 100%) of the activity of the original Cas9 protein or nucleobase editor. In some embodiments, the split Cas9 protein or split nucleobase editor is more active (e.g., 2-fold, 5-fold, 10-fold, 100-fold, 1000-fold, or more) than that of an original Cas9 protein or nucleobase editor. 
     The compositions described herein may be administered to a subject in need thereof in a therapeutically effective amount to treat and/or prevent a disease or disorder the subject is suffering from. Any disease or disorder that maybe treated and/or prevented using CRISPR/Cas9-based genome-editing technology may be treated by the split Cas9 protein or the split nucleobase editor described herein. It is to be understood that, if the nucleotide sequences encoding the split Cas9 protein or the nucleobase editor does not further encode a gRNA, a separate nucleic acid vector encoding the gRNA may be administered together with the compositions described herein.

     Suitable routes of administrating the composition for pain suppression include, without limitation: topical, subcutaneous, transdermal, intradermal, intralesional, intraarticular, intraperitoneal, intravesical, transmucosal, gingival, intradental, intracochlear, transtympanic, intraorgan, epidural, intrathecal, intramuscular, intravenous, intravascular, intraosseus, periocular, intratumoral, intracerebral, parenteral, and intracerebroventricular administration. 
     The compositions of this disclosure may be administered or packaged as a unit dose, for example. The term “unit dose” when used in reference to a pharmaceutical composition of the present disclosure refers to physically discrete units suitable as unitary dosage for the subject, each unit containing a predetermined quantity of active material calculated to produce the desired therapeutic effect in association with the required diluent, i.e., a carrier or vehicle. 
     Treatment of a disease or disorder includes delaying the development or progression of the disease, or reducing disease severity. Treating the disease does not necessarily require curative results. 
     As used therein, “delaying” the development of a disease means to defer, hinder, slow, retard, stabilize, and/or postpone progression of the disease. This delay can be of varying lengths of time, depending on the history of the disease and/or individuals being treated. A method that “delays” or alleviates the development of a disease, or delays the onset of the disease, is a method that reduces probability of developing one or more symptoms of the disease in a given time frame and/or reduces extent of the symptoms in a given time frame, when compared to not using the method. Such comparisons are typically based on clinical studies, using a number of subjects sufficient to give a statistically significant result. 
     “Development” or “progression” of a disease means initial manifestations and/or ensuing progression of the disease. Development of the disease can be detectable and assessed using standard clinical techniques as well known in the art. However, development also refers to progression that may be undetectable. For purpose of this disclosure, development or progression refers to the biological course of the symptoms. “Development” includes occurrence, recurrence, and onset. 
     As used herein “onset” or “occurrence” of a disease includes initial onset and/or recurrence. Conventional methods, known to those of ordinary skill in the art of medicine, can be used to administer the isolated polypeptide or pharmaceutical composition to the subject, depending upon the type of disease to be treated or the site of the disease. 
     Kits 
     The compositions of the present disclosure may be assembled into kits. In some embodiments, the kit comprises nucleic acid vectors for the expression of the nucleobase editors described herein. In some embodiments, the kit further comprises appropriate guide nucleotide sequences (e.g., gRNAs) or nucleic acid vectors for the expression of such guide nucleotide sequences, to target the Cas9 protein or nucleobase editor to the desired target sequence. 
     The kit described herein may include one or more containers housing components for performing the methods described herein and optionally instructions for use. Any of the kit described herein may further comprise components needed for performing the assay methods. Each component of the kits, where applicable, may be provided in liquid form (e.g., in solution) or in solid form, (e.g., a dry powder). In certain cases, some of the components may be reconstitutable or otherwise processible (e.g., to an active form), for example, by the addition of a suitable solvent or other species (for example, water), which may or may not be provided with the kit. 
     In some embodiments, the kits may optionally include instructions and/or promotion for use of the components provided. As used herein, “instructions” can define a component of instruction and/or promotion, and typically involve written instructions on or associated with packaging of the disclosure. Instructions also can include any oral or electronic instructions provided in any manner such that a user will clearly recognize that the instructions are to be associated with the kit, for example, audiovisual (e.g., videotape, DVD, etc.), Internet, and/or web-based communications, etc. The written instructions may be in a form prescribed by a governmental agency regulating the manufacture, use, or sale of pharmaceuticals or biological products, which can also reflect approval by the agency of manufacture, use or sale for animal administration. As used herein, “promoted” includes all methods of doing business including methods of education, hospital and other clinical instruction, scientific inquiry, drug discovery or development, academic research, pharmaceutical industry activity including pharmaceutical sales, and any advertising or other promotional activity including written, oral and electronic communication of any form, associated with the disclosure. Additionally, the kits may include other components depending on the specific application, as described herein.

     Host Cells 
     Cells that may contain any of the compositions described herein include prokaryotic cells and eukaryotic cells. The methods described herein are used to deliver a Cas9 protein or a nucleobase editor into a eukaryotic cell (e.g., a mammalian cell, such as a human cell). In some embodiments, the cell is in vitro (e.g., cultured cell. In some embodiments, the cell is in vivo (e.g., in a subject such as a human subject). In some embodiments, the cell is ex vivo (e.g., isolated from a subject and may be administered back to the same or a different subject). 
     Mammalian cells of the present disclosure include human cells, primate cells (e.g., vero cells), rat cells (e.g., GH3 cells, OC23 cells) or mouse cells (e.g., MC3T3 cells). There are a variety of human cell lines, including, without limitation, human embryonic kidney (HEK) cells, HeLa cells, cancer cells from the National Cancer Institute&#39;s 60 cancer cell lines (NCI60), DU145 (prostate cancer) cells, Lncap (prostate cancer) cells, MCF-7 (breast cancer) cells, MDA-MB-438 (breast cancer) cells, PC3 (prostate cancer) cells, T47D (breast cancer) cells, THP-1 (acute myeloid leukemia) cells, U87 (glioblastoma) cells, SHSY5Y human neuroblastoma cells (cloned from a myeloma) and Saos-2 (bone cancer) cells. In some embodiments, rAAV vectors are delivered into human embryonic kidney (HEK) cells (e.g., HEK 293 or HEK 293T cells). In some embodiments, rAAV vectors are delivered into stem cells (e.g., human stem cells) such as, for example, pluripotent stem cells (e.g., human pluripotent stem cells including human induced pluripotent stem cells (hiPSCs)). A stem cell refers to a cell with the ability to divide for indefinite periods in culture and to give rise to specialized cells. A pluripotent stem cell refers to a type of stem cell that is capable of differentiating into all tissues of an organism, but not alone capable of sustaining full organismal development. A human induced pluripotent stem cell refers to a somatic (e.g., mature or adult) cell that has been reprogrammed to an embryonic stem cell-like state by being forced to express genes and factors important for maintaining the defining properties of embryonic stem cells (see, e.g., Takahashi and Yamanaka, Cell 126 (4): 663-76, 2006, incorporated by reference herein). Human induced pluripotent stem cell cells express stem cell markers and are capable of generating cells characteristic of all three germ layers (ectoderm, endoderm, mesoderm).

     EXAMPLES 
     In order that the invention described herein may be more fully understood, the following examples are set forth. The synthetic examples described in this application are offered to illustrate the compounds and methods provided herein and are not to be construed in any way as limiting their scope. 
     Example 1: Amino Acid Sequences of Cas9 Proteins and Nucleobase Editor 
     Non-limiting examples of suitable Cas9 proteins and variants, and nucleobase editors and variants are provided. The disclosure provides Cas9 variants, for example, Cas9 proteins from one or more organisms, which may comprise one or more mutations (e.g., to generate dCas9 or Cas9 nickase). In some embodiments, one or more of the amino acid residues, identified below by an asterisk, of a Cas9 protein may be mutated. In some embodiments, the D10 and/or H840 residues of the amino acid sequence provided in SEQ ID NO: 1, or a corresponding mutation in any of the amino acid sequences provided in SEQ ID NOs: 2-275 and 394-397, are mutated. In some embodiments, the D10 residue of the amino acid sequence provided in SEQ ID NO: 1, or a corresponding mutation in any of the amino acid sequences provided in SEQ ID NOs: 2-275 and 394-397, is mutated to any amino acid residue, except for D. In some embodiments, the D10 residue of the amino acid sequence provided in SEQ ID NO: 1, or a corresponding mutation in any of the amino acid sequences provided in SEQ ID NOs: 2-275 and 394-397, is mutated to an A. In some embodiments, the H840 residue of the amino acid sequence provided in SEQ ID NO: 1, or a corresponding residue in any of the amino acid sequences provided in SEQ ID NOs: 2-275 and 394-397, is an H. In some embodiments, the H840 residue of the amino acid sequence provided in SEQ ID NO: 1, or a corresponding mutation in any of the amino acid sequences provided in SEQ ID NOs: 2-275 and 394-397, is mutated to any amino acid residue, except for H. In some embodiments, the H840 residue of the amino acid sequence provided in SEQ ID NO: 1, or a corresponding mutation in any of the amino acid sequences provided in SEQ ID NOs: 2-275 and 394-397, is mutated to an A. In some embodiments, the D10 residue of the amino acid sequence provided in SEQ ID NO: 1, or a corresponding residue in any of the amino acid sequences provided in SEQ ID NOs: 2-275 and 394-397, is a D. 
     A number of Cas9 sequences from various species were aligned to determine whether corresponding homologous amino acid residues of D10 and H840 of SEQ ID NO: 1 can be identified in other Cas9 proteins, allowing the generation of Cas9 variants with corresponding mutations of the homologous amino acid residues. The alignment was carried out using the NCBI Constraint-based Multiple Alignment Tool (COBALT (accessible at st-va.ncbi.nlm.nih.gov/tools/cobalt)), with the following parameters. Alignment parameters: Gap penalties −11,−1; End-Gap penalties −5,−1. CDD Parameters: Use RPS BLAST on; Blast E-value 0.003; Find Conserved columns and Recompute on. Query Clustering Parameters: Use query clusters on; Word Size 4; Max cluster distance 0.8; Alphabet Regular.

     An exemplary alignment of four Cas9 sequences is provided below. The Cas9 sequences in the alignment are: Sequence 1 (S1): SEQ ID NO: 1|WP_010922251|gi 499224711|type II CRISPR RNA-guided endonuclease Cas9 [ Streptococcus pyogenes ]; Sequence 2 (S2): SEQ ID NO: 27|WP_039695303|gi 746743737|type II CRISPR RNA-guided endonuclease Cas9 [ Streptococcus gallolyticus ]; Sequence 3 (S3): SEQ ID NO: 28|WP_045635197|gi 782887988|type II CRISPR RNA-guided endonuclease Cas9 [ Streptococcus mitis ]; Sequence 4 (S4): SEQ ID NO: 29|5AXW_A|gi 924443546| Staphylococcus aureus  Cas9. The HNH domain (bold and underlined) and the RuvC domain (boxed) are identified for each of the four sequences. Amino acid residues 10 and 840 in 51 and the homologous amino acids in the aligned sequences are identified with an asterisk following the respective amino acid residue.

     The alignment demonstrates that amino acid sequences and amino acid residues that are homologous to a reference Cas9 amino acid sequence or amino acid residue can be identified across Cas9 sequence variants, including, but not limited to Cas9 sequences from different species, by identifying the amino acid sequence or residue that aligns with the reference sequence or the reference residue using alignment programs and algorithms known in the art. This disclosure provides Cas9 variants in which one or more of the amino acid residues identified by an asterisk in SEQ ID NOs: 1 and 27-29 (e.g., S1, S2, S3, and S4, respectively) are mutated as described herein. The residues D10 and H840 in Cas9 of SEQ ID NO: 1 that correspond to the residues identified in SEQ ID NOs: 1 and 27-29 by an asterisk are referred to herein as “homologous” or “corresponding” residues. Such homologous residues can be identified by sequence alignment, e.g., as described above, and by identifying the sequence or residue that aligns with the reference sequence or residue. Similarly, mutations in Cas9 sequences that correspond to mutations identified in SEQ ID NO: 1 herein, e.g., mutations of residues 10, and 840 in SEQ ID NO: 1, are referred to herein as “homologous” or “corresponding” mutations. For example, the mutations corresponding to the D10A mutation in SEQ ID NO: 1 (S1) for the four aligned sequences above are D11A for S2, D10A for S3, and D13A for S4; the corresponding mutations for H840A in SEQ ID NO: 1 (S1) are H850A for S2, H842A for S3, and H560A for S4. 
     A total of 250 Cas9 sequences (SEQ ID NOs: 1 and 27-275) from different species are provided. Amino acid residues corresponding to residues 10 and 840 of SEQ ID NO: 1 may be identified in the same manner as outlined above. All of these Cas9 sequences may be used in accordance with the present disclosure.

     Example 2: AAV Delivery of Split Nucleobase Editor 
     This study was designed to show that a nucleobase editor may be delivered by recombinant AAV (rAAV) in two sections, which may be joined to form a complete and active nucleobase editor in cells via protein splicing. Different elements of the rAAV constructs were tested for optimized nucleobase editor expression and activity. 
     Recombinant AAV (rAAV) is widely used for transgene delivery. Transgenes were inserted into the AAV genome between the inverted terminal repeat (ITR) sequences and packaged into AAV viral particles, which are used to transduce a host cell (e.g., mammalian cell, human cell). However, there is a limitation on the size of the transgene that may be packaged into rAAV, typically approximately 4.9 kilobases. Nucleic acids encoding a nucleobase editor (e.g., cytosine deaminase-dCas9-UGI) typically exceed the packaging limit of rAAV. As described herein, the nucleic acids encoding a nucleobase editor were split (see  FIG. 1A ), and each section was packaged into a separate rAAV particle. The two sections of the nucleobase editor were delivered to the cells and can be ligated to form a complete nucleobase editor via protein splicing (e.g., mediated by an intein, such as the DnaE intein; see  FIG. 1C ). The ligated, complete nucleobase editor was active in editing target bases (see  FIG. 1B ). The rAAV constructs encoding the split nucleobase editors were tested in different cell lines, e.g., U118 and HEK293T, and are active in editing the target base (see  FIGS. 3A-3B  and  FIGS. 5A-5B ). 
     Different transcriptional terminators and nuclear localization signals (NLS) were tested in the rAAV constructs to optimize the expression and activity of the nucleobase editors (see  FIGS. 4, 6, and 7 ). 
     Example 3: Editing of DNMT1 Gene in Mouse Neuron Using AAV Encoded Split Nucleobase Editor 
     This study was designed to test the base editing activity of an AAV encoded split nucleobase editor in vivo. A split nucleobase editor as shown in  FIG. 1A  was used. The amino acid sequence of the linker between the dCas9 domain and the deaminase domain is SGGSSGGSSGSETPGTSESATPESSGGSSGGS (SEQ ID NO: 384). A guide RNA targeting a well-characterized site in the DNMT1 gene was selected. It was expected that the cells would be able to tolerate the editing. These experiments aim to determine whether AAV encoded split base editor can edit the locus in vitro or in vivo in several cell types including primary neurons. 
     In one experiment, AAV vectors encoding the split nucleobase editor and a guide RNA targeting DNMT1 were used to transduce dissociated mouse cortical neurons, two days after the cortical neurons were isolated and cultured. The neurons were harvested 16 days post transduction and the DNMT1 gene was sequenced ( FIG. 8A ) to determine editing efficiency as well as off-target effects. An editing efficiency of 17.34% (C to T editing, darker grey in  FIG. 8B ) was detected, while only 0.82% of undesired editing (C to G or C to A change, lighter grey in  FIG. 8B ) was detected. 
     In another experiment, cultured mouse Neuro-2 cells were either transduced with AAV vectors encoding the split nucleobase editor and a guide RNA targeting DNMT1, or transfected with lipid-encapsulated DNA encoding the nucleobase editor and guide RNA, allowing direct comparison of editing efficiency using different delivery methods of the nucleobase editor ( FIG. 9A ). An editing efficiency of 5.96% (C to T editing, dark grey in  FIG. 9B ) was observed for AAV encoded split nucleobase editor, while an editing efficiency of 27.3% (C to T editing, dark grey in  FIG. 9B ) was observed for lipid-transfected DNA encoded nucleobase editor. The amount of undesired products was 0.15% for AAV encoded split nucleobase editor and 1.3% for lipid-transfected DNA encoded nucleobase editor (C to G or C to A change, lighter grey in  FIG. 9B ).
