## Title
Position dependent recognition of GNN nucleotide triplets by zinc fingers

## Abstract

The specificity of binding of a zinc finger to a triplet or quadruplet nucleotide target subsite depends upon the location of the zinc finger in a multifinger protein and, hence, upon the location of its target subsite within a larger target sequence. The present disclosure provides zinc finger amino acid sequences for recognition of triplet target subsites having the nucleotide G in the 5′-most position of the subsite, that have been optimized with respect to the location of the subsite within the target site. Accordingly, the disclosure provides finger position-specific amino acid sequences for the recognition of GNN target subsites. This allows the construction of multi-finger zinc finger proteins with improved affinity and specificity for their target sequences, as well as enhanced biological activity.

BACKGROUND
Zinc finger proteins (ZFPs) are proteins that can bind to DNA in a sequence-specific manner. Zinc fingers were first identified in the transcription factor TFIIIA from the oocytes of the African clawed toad, Xenopus laevis. An exemplary motif characterizing one class of these protein (C2H2 class) is -Cys-(X)2-4-Cys-(X)12-His-(X)3-5-His (where X is any amino acid) (SEQ. ID. No:1). A single finger domain is about 30 amino acids in length, and several structural studies have demonstrated that it contains an alpha helix containing the two invariant histidine residues and two invariant cysteine residues in a beta turn co-ordinated through zinc. To date, over 10,000 zinc finger sequences have been identified in several thousand known or putative transcription factors. Zinc finger domains are involved not only in DNA-recognition, but also in RNA binding and in protein-protein binding. Current estimates are that this class of molecules will constitute about 2% of all human genes.
The x-ray crystal structure of Zif268, a three-finger domain from a murine transcription factor, has been solved in complex with a cognate DNA sequence and shows that each finger can be superimposed on the next by a periodic rotation. The structure suggests that each finger interacts independently with DNA over 3 base-pair intervals, with side-chains at positions −1, 2, 3 and 6 on each recognition helix making contacts with their respective DNA triplet subsites. The amino terminus of Zif268 is situated at the 3′ end of the DNA strand with which it makes most contacts. Some zinc fingers can bind to a fourth base in a target segment. If the strand with which a zinc finger protein makes most contacts is designated the target strand, some zinc finger proteins bind to a three base triplet in the target strand and a fourth base on the nontarget strand. The fourth base is complementary to the base immediately 3′ of the three base subsite.
The structure of the Zif268-DNA complex also suggested that the DNA sequence specificity of a zinc finger protein might be altered by making amino acid substitutions at the four helix positions (−1, 2, 3 and 6) on each of the zinc finger recognition helices. Phage display experiments using zinc finger combinatorial libraries to test this observation were published in a series of papers in 1994 (Rebar et al., Science 263, 671-673 (1994); Jamieson et al., Biochemistry 33, 5689-5695 (1994); Choo et al, PNAS 91, 11163-11167 (1994)). Combinatorial libraries were constructed with randomized side-chains in either the first or middle finger of Zif268 and then used to select for an altered Zif268 binding site in which the appropriate DNA sub-site was replaced by an altered DNA triplet. Further, correlation between the nature of introduced mutations and the resulting alteration in binding specificity gave rise to a partial set of substitution rules for design of ZFPs with altered binding specificity.
Greisman & Pabo, Science 275, 657-661 (1997) discuss an elaboration of the phage display method in which each finger of a Zif268 was successively randomized and selected for binding to a new triplet sequence. This paper reported selection of ZFPs for a nuclear hormone response element, a p53 target site and a TATA box sequence.
A number of papers have reported attempts to produce ZFPs to modulate particular target sites. For example, Choo et al., Nature 372, 645 (1994), report an attempt to design a ZFP that would repress expression of a bcr-abl oncogene. The target segment to which the ZFPs would bind was a nine base sequence 5′GCA GAA GCC3′ chosen to overlap the junction created by a specific oncogenic translocation fusing the genes encoding bcr and abl. The intention was that a ZFP specific to this target site would bind to the oncogene without binding to abl or bcr component genes. The authors used phage display to screen a mini-library of variant ZFPs for binding to this target segment. A variant ZFP thus isolated was then reported to repress expression of a stably transfected bcr-able construct in a cell line.
Pomerantz et al., Science 267, 93-96 (1995) reported an attempt to design a novel DNA binding protein by fusing two fingers from Zif268 with a homeodomain from Oct-1. The hybrid protein was then fused with a transcriptional activator for expression as a chimeric protein. The chimeric protein was reported to bind a target site representing a hybrid of the subsites of its two components. The authors then constructed a reporter vector containing a luciferase gene operably linked to a promoter and a hybrid site for the chimeric DNA binding protein in proximity to the promoter. The authors reported that their chimeric DNA binding protein could activate expression of the luciferase gene.
Liu et al., PNAS 94, 5525-5530 (1997) report forming a composite zinc finger protein by using a peptide spacer to link two component zinc finger proteins each having three fingers. The composite protein was then further linked to transcriptional activation domain It was reported that the resulting chimeric protein bound to a target site formed from the target segments bound by the two component zinc finger proteins. It was further reported that the chimeric zinc finger protein could activate transcription of a reporter gene when its target site was inserted into a reporter plasmid in proximity to a promoter operably linked to the reporter.
Choo et al., WO 98/53058, WO98/53059, and WO 98/53060 (1998) discuss selection of zinc finger proteins to bind to a target site within the HIV Tat gene. Choo et al. also discuss selection of a zinc finger protein to bind to a target site encompassing a site of a common mutation in the oncogene ras. The target site within ras was thus constrained by the position of the mutation.
Previously-disclosed methods for the design of sequence-specific zinc finger proteins have often been based on modularity of individual zinc fingers; i.e., the ability of a zinc finger to recognize the same target subsite regardless of the location of the finger in a multi-finger protein. Although, in many instances, a zinc finger retains the same sequence specificity regardless of its location within a multi-finger protein; in certain cases, the sequence specificity of a zinc finger depends on its position. For example, it is possible for a finger to recognize a particular triplet sequence when it is present as finger 1 of a three-finger protein, but to recognize a different triplet sequence when present as finger 2 of a three-finger protein.
Attempts to address situations in which a zinc finger behaves in a non-modular fashion (i.e., its sequence specificity depends upon its location in a multi-finger protein) have, to date, involved strategies employing randomization of key binding residues in multiple adjacent zinc fingers, followed by selection. See, for example, Isalan et al. (2001) Nature Biotechnol. 19:656-660. However, methods for rational design of polypeptides containing non-modular zinc fingers have not heretofore been described.

BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 shows results of site selection analysis of two representative zinc finger proteins (leftmost 4 columns) and measurements of binding affinity for each of these proteins to their intended target sequences and to variant target sequences. (rightmost 3 columns). Analysis of ZFP1 is shown in the upper portion of the figure and analysis of ZFP2 is shown in the lower portion of the figure. For the site selection analyses, the amino acid sequences of residues −1 through +6 of the recognition helix of each of the three component zinc fingers (F3 (ZFP1, SEQ ID NO:130; ZFP2, SEQ ID NO:420), F2 (ZFP1, SEQ ID NO:1051; ZFP2, SEQ ID NO:889) and F1 (ZFP1, SEQ ID NO:395; ZFP2, SEQ ID NO:685)) are shown across the top row; the intended target sequence (divided into finger-specific target subsites) is shown across the second row, and a summary of the sequences bound is shown in the third row. Data for F3 is shown in the second column, data for F2 is shown in the third column, and data for F1 is shown in the third column.
For the binding affinity analyses, the designed target sequence for each ZFP (“cognate”) and two related sequences (“Mt”) are shown (column 6), along with the Kd for binding of the ZFP to each of these sequences (column 7).
FIG. 2 shows amino acid sequences of zinc finger recognition regions (amino acids −1 through +6 of the recognition helix) that bind to each of the 16 GNN triplet subsites. Three amino acid sequences are shown for each trinucleotide subsite; these correspond to optimal amino acid sequences for recognition of the subsite from each of the three positions (finger 1, F1 (SEQ ID NOS:688, 2534, 676, 1769, 342, 1450, 131, 158, 1765, 395, 1407, 2644, 705, 1398, 1733 & 184); finger 2, F2 (SEQ ID NOS:688, 229, 1446, 3051, 220, 1450, 417, 801, 1442, 395, 1824, 1201, 972, 3339, 1151 & 184); or finger 3, F3 (SEQ ID NOS:943, 229, 676, 1769, 220, 1365, 417, 801, 3525, 395, 1824, 1425, 972, 3592, 952 & 184)) in a three-finger zinc finger protein Amino acid sequences are from N-terminal to C-terminal; nucleotide sequences are from 5′ to 3′.
Also shown are site selection results for each of the 48 position-dependent GNN-recognizing zinc fingers. These show the number of times a particular nucleotide was present, at a given position, in a collection of oligonucleotide sequences bound by the finger. For example, out of 15 oligonucleotides bound by a zinc finger protein with the amino acid sequence QSGHLAR (SEQ ID NO:413) present at the finger 1 (F1) position, 15 contained a G in the 5′-most position of the subsite, 15 contained a G in the middle position of the subsite, while, at the 3′-most position of the subsite, 10 contained an A, 3 contained a G and 2 contained a T. Accordingly, this particular amino acid sequence is optimal for binding a GGA triplet from the F1 position.
FIGS. 3A, 3B and 3C show site selection data indicating positional dependence of GCA-, GAT- and GGT-binding zinc fingers. The first and fourth (where applicable) rows of each figure show portions of the amino acid sequence of a designed zinc finger protein (F1 column, SEQ ID NOS:220, 1765, 1442, 835 & 1425; F2 column, SEQ ID NOS:220, 1765, 1442, 889, 1425; F3 column, SEQ ID NOS:220, 159, 377, 889 & 1425). Amino acid residues-1 through +6 of each α-helix are listed from left to right. The second and fifth (where applicable) rows show the target sequence, divided into three triplet subsites, one for each finger of the protein shown in the first and fourth (where applicable) rows, respectively. The third and sixth (where applicable) rows show the distribution of nucleotides in the oligonucleotides obtained by site selection with the proteins shown in the first and fourth (where applicable) rows, respectively. FIG. 3A shows data for fingers designed to bind GCA; FIG. 3B shows data for fingers designed to bind GAT; FIG. 3C shows data for fingers designed to bind GGT.
FIGS. 4A and 4B show properties of the engineered ZFP EP2C. FIG. 4A shows site selection data. The first row provides the amino acid sequences (F3, SEQ ID NO:1100; F2, SEQ ID NO:237; F1, SEQ ID NO:1450) of residues −1 through +6 of the recognition helices for each of the three zinc fingers of the EP2C protein. The second row shows the target sequence (5′ to 3′); with the distribution of nucleotides in the oligonucleotides obtained by site selection indicated below the target sequence.



FIG. 4B shows in vitro and in vivo assays for the binding specificity of EP2C. The first three columns show in vitro measurements of binding affinity of EP2C to its intended target sequence and several related sequences. The first column gives the name of each sequence (2C0 is the intended target sequence, compare to FIG. 4A). The second column shows the nucleotide sequence of various target sequences, with differences from the intended target sequence (2C0) highlighted. The third column shows the Kd (in nM) for binding of EP2C to each of the target sequences. Kds were determined by gel shift assays, using 2-fold dilution series of EP2C. The right side of the figure (fourth column and bar graph) shows relative luciferase activities (normalized to β-galactosidase levels) in stable cell lines in which expression of EP2C is inducible. Cells were co-transfected with a vector containing a luciferase coding region under the transcriptional control of the target sequence shown in the same row of the figure, and a control vector encoding β-galactosidase. Luciferase and β-galactosidase levels were measured after induction of EP2C expression. Triplicate samples were assayed and the standard deviations are shown in the bar graph. pGL3 is a luciferase-encoding vector lacking EP2C target sequences. 3B is another negative control, in which luciferase expression is under transcriptional control of sequences (3B) unrelated to the EP2C target sequence.
DEFINITIONS
A zinc finger DNA binding protein is a protein or segment within a larger protein that binds DNA in a sequence-specific manner as a result of stabilization of protein structure through coordination of a zinc ion. The term zinc finger DNA binding protein is often abbreviated as zinc finger protein or ZFP.
Zinc finger proteins can be engineered to recognize a selected target sequence in a nucleic acid. Any method known in the art or disclosed herein can be used to construct an engineered zinc finger protein or a nucleic acid encoding an engineered zinc finger protein. These include, but are not limited to, rational design, selection methods (e.g., phage display) random mutagenesis, combinatorial libraries, computer design, affinity selection, use of databases matching zinc finger amino acid sequences with target subsite nucleotide sequences, cloning from cDNA and/or genomic libraries, and synthetic constructions. An engineered zinc finger protein can comprise a new combination of naturally-occurring zinc finger sequences. Methods for engineering zinc finger proteins are disclosed in co-owned WO 00/41566 and WO 00/42219; as well as in WO 98/53057; WO 98/53058; WO 98/53059 and WO 98/53060; the disclosures of which are hereby incorporated by reference in their entireties. Methods for identifying preferred target sequences, and for engineering zinc finger proteins to bind to such preferred target sequences, are disclosed in co-owned WO 00/42219.
A designed zinc finger protein is a protein not occurring in nature whose design/composition results principally from rational criteria. Rational criteria for design include application of substitution rules and computerized algorithms for processing information in a database storing information of existing ZFP designs and binding data.
A selected zinc finger protein is a protein not found in nature whose production results primarily from an empirical process such as phage display.
The term naturally-occurring is used to describe an object that can be found in nature as distinct from being artificially produced by man. For example, a polypeptide or polynucleotide sequence that is present in an organism (including viruses) that can be isolated from a source in nature and which has not been intentionally modified by man in the laboratory is naturally-occurring. Generally, the term naturally-occurring refers to an object as present in a non-pathological (undiseased) individual, such as would be typical for the species.
A nucleic acid is operably linked when it is placed into a functional relationship with another nucleic acid sequence. For instance, a promoter or enhancer is operably linked to a coding sequence if it increases the transcription of the coding sequence. Operably linked means that the DNA sequences being linked are typically contiguous and, where necessary to join two protein coding regions, contiguous and in reading frame. However, since enhancers generally function when separated from the promoter by up to several kilobases or more and intronic sequences may be of variable lengths, some polynucleotide elements may be operably linked but not contiguous.
A specific binding affinity between, for example, a ZFP and a specific target site means a binding affinity of at least 1×106 M−1.
The terms “modulating expression” “inhibiting expression” and “activating expression” of a gene refer to the ability of a zinc finger protein to activate or inhibit transcription of a gene. Activation includes prevention of subsequent transcriptional inhibition (i.e., prevention of repression of gene expression) and inhibition includes prevention of subsequent transcriptional activation (i.e., prevention of gene activation). Modulation can be assayed by determining any parameter that is indirectly or directly affected by the expression of the target gene. Such parameters include, e.g., changes in RNA or protein levels, changes in protein activity, changes in product levels, changes in downstream gene expression, changes in reporter gene transcription (luciferase, CAT, beta-galactosidase, GFP (see, e.g., Mistili & Spector, Nature Biotechnology 15:961-964 (1997)); changes in signal transduction, phosphorylation and dephosphorylation, receptor-ligand interactions, second messenger concentrations (e.g., cGMP, cAMP, IP3, and Ca2+), cell growth, neovascularization, in vitro, in vivo, and ex vivo. Such functional effects can be measured by any means known to those skilled in the art, e.g., measurement of RNA or protein levels, measurement of RNA stability, identification of downstream or reporter gene expression, e.g., via chemiluminescence, fluorescence, colorimetric reactions, antibody binding, inducible markers, ligand binding assays; changes in intracellular second messengers such as cGMP and inositol triphosphate (IP3); changes in intracellular calcium levels; cytokine release, and the like.
A “regulatory domain” refers to a protein or a protein subsequence that has transcriptional modulation activity. Typically, a regulatory domain is covalently or non-covalently linked to a ZFP to modulate transcription. Alternatively, a ZFP can act alone, without a regulatory domain, or with multiple regulatory domains to modulate transcription.
A D-able subsite within a target site has the motif 5′NNGK3′ (SEQ ID NO:4084). A target site containing one or more such motifs is sometimes described as a D-able target site. A zinc finger appropriately designed to bind to a D-able subsite is sometimes referred to as a D-able finger. Likewise a zinc finger protein containing at least one finger designed or selected to bind to a target site including at least one D-able subsite is sometimes referred to as a D-able zinc finger protein.
DETAILED DESCRIPTION
I. General
Tables 1-5 list a collection of nonnaturally occurring zinc finger protein sequences and their corresponding target sites. The first column of each table is an internal reference number. The second column lists a 9 or 10 base target site bound by a three-finger zinc finger protein, with the target sites listed in 5′ to 3′ orientation. The third column provides SEQ ID NOs for the target site sequences listed in column 2. The fourth, sixth and eighth columns list amino acid residues from the first, second and third fingers, respectively, of a zinc finger protein which recognizes the target sequence listed in the second column. For each finger, seven amino acids, occupying positions −1 to +6 of the finger, are listed. The numbering convention for zinc fingers is defined below. Columns 5, 7 and 9 provide SEQ ID NOs for the amino acid sequences listed in columns 4, 6 and 8, respectively. The final column of each table lists the binding affinity (i.e., the Kd in nM) of the zinc finger protein for its target site. Binding affinities are measured as described below.
Each finger binds to a triplet of bases within a corresponding target sequence. The first finger binds to the first triplet starting from the 3′ end of a target site, the second finger binds to the second triplet, and the third finger binds the third (i.e., the 5′-most) triplet of the target sequence. For example, the RSDSLTS finger (SEQ ID NO: 646) of SBS#201 (Table 2) binds to 5′TTG3′, the ERSTLTR finger (SEQ ID NO: 851) binds to 5′GCC3′ and the QRADLRR finger (SEQ ID NO: 1056) binds to 5′GCA3′.
Table 6 lists a collection of consensus sequences for zinc fingers and the target sites bound by such sequences. Conventional one letter amino acid codes are used to designate amino acids occupying consensus positions. The symbol “X” designates a nonconsensus position that can in principle be occupied by any amino acid. In most zinc fingers of the C2H2 type, binding specificity is principally conferred by residues −1, +2, +3 and +6. Accordingly, consensus sequence determining binding specificity typically include at least these residues. Consensus sequences are useful for designing zinc fingers to bind to a given target sequence. Residues occupying other positions can be selected based on sequences in Tables 1-5, or other known zinc finger sequences. Alternatively, these positions can be randomized with a plurality of candidate amino acids and screened against one or more target sequences to refine binding specificity or improve binding specificity. In general, the same consensus sequence can be used for design of a zinc finger regardless of the relative position of that finger in a multi-finger zinc finger protein. For example, the sequence RXDNXXR (SEQ ID NO:4060) can be used to design a N-terminal, central or C-terminal finger of three finger protein. However, some consensus sequences are most suitable for designing a zinc finger to occupy a particular position in a multi-finger protein. For example, the consensus sequence RXDHXXQ (SEQ ID NO:4055) is most suitable for designing a C-terminal finger of a three-finger protein.
II. Characteristics of Zinc Finger Proteins
Zinc finger proteins are formed from zinc finger components. For example, zinc finger proteins can have one to thirty-seven fingers, commonly having 2, 3, 4, 5 or 6 fingers. A zinc finger protein recognizes and binds to a target site (sometimes referred to as a target segment) that represents a relatively small subsequence within a target gene. Each component finger of a zinc finger protein can bind to a subsite within the target site. The subsite includes a triplet of three contiguous bases all on the same strand (sometimes referred to as the target strand). The subsite may or may not also include a fourth base on the opposite strand that is the complement of the base immediately 3′ of the three contiguous bases on the target strand. In many zinc finger proteins, a zinc finger binds to its triplet subsite substantially independently of other fingers in the same zinc finger protein. Accordingly, the binding specificity of zinc finger protein containing multiple fingers is usually approximately the aggregate of the specificities of its component fingers. For example, if a zinc finger protein is formed from first, second and third fingers that individually bind to triplets XXX, YYY, and ZZZ, the binding specificity of the zinc finger protein is 3′XXX YYY ZZZ5′.
The relative order of fingers in a zinc finger protein from N-terminal to C-terminal determines the relative order of triplets in the 3′ to 5′ direction in the target. For example, if a zinc finger protein comprises from N-terminal to C-terminal first, second and third fingers that individually bind, respectively, to triplets 5′ GAC3′, 5′GTA3′ and 5′GGC3′ then the zinc finger protein binds to the target segment 3′CAGATGCGG5′. If the zinc finger protein comprises the fingers in another order, for example, second finger, first finger, third finger, then the zinc finger protein binds to a target segment comprising a different permutation of triplets, in this example, 3′ATGCAGCGG5′ (see Berg & Shi, Science 271, 1081-1086 (1996)). The assessment of binding properties of a zinc finger protein as the aggregate of its component fingers may, in some cases, be influenced by context-dependent interactions of multiple fingers binding in the same protein.
Two or more zinc finger proteins can be linked to have a target specificity that is the aggregate of that of the component zinc finger proteins (see e.g., Kim & Pabo, PNAS 95, 2812-2817 (1998)). For example, a first zinc finger protein having first, second and third component fingers that respectively bind to XXX, YYY and ZZZ can be linked to a second zinc finger protein having first, second and third component fingers with binding specificities, AAA, BBB and CCC. The binding specificity of the combined first and second proteins is thus 3′XXXYYYZZZ_AAABBBCCC5′, where the underline indicates a short intervening region (typically 0-5 bases of any type). In this situation, the target site can be viewed as comprising two target segments separated by an intervening segment.
Linkage can be accomplished using any of the following peptide linkers. T G E K P: (SEQ. ID. No:2) (Liu et al., 1997, supra.); (G4S)n (SEQ. ID. No:3) (Kim et al., PNAS 93, 1156-1160 (1996.); GGRRGGGS; (SEQ. ID. No:4) LRQRDGERP; (SEQ. ID. No:5) LRQKDGGGSERP; (SEQ. ID. No:6) LRQKD(G3S)2 ERP (SEQ. ID. No:7) Alternatively, flexible linkers can be rationally designed using computer programs capable of modeling both DNA-binding sites and the peptides themselves or by phage display methods. In a further variation, noncovalent linkage can be achieved by fusing two zinc finger proteins with domains promoting heterodimer formation of the two zinc finger proteins. For example, one zinc finger protein can be fused with fos and the other with jun (see Barbas et al., WO 95/119431).
Linkage of two zinc finger proteins is advantageous for conferring a unique binding specificity within a mammalian genome. A typical mammalian diploid genome consists of 3×109 bp. Assuming that the four nucleotides A, C, G, and T are randomly distributed, a given 9 bp sequence is present  ̃23,000 times. Thus a ZFP recognizing a 9 bp target with absolute specificity would have the potential to bind to  ̃23,000 sites within the genome. An 18 bp sequence is present once in 3.4×1010 bp, or about once in a random DNA sequence whose complexity is ten times that of a mammalian genome.
A component finger of zinc finger protein typically contains about 30 amino acids and has the following motif (N—C):










Cys-(X)2-4-Cys-
(SEQ. ID. No: 8)









X.X.X.X.X.X.X.X.X.X.X.X-His-(X)3-5-His



         −1 1 2 3 4 5 6 7






The two invariant histidine residues and two invariant cysteine residues in a single beta turn are co-ordinated through zinc (see, e.g., Berg & Shi, Science 271, 1081-1085 (1996)). The above motif shows a numbering convention that is standard in the field for the region of a zinc finger conferring binding specificity. The amino acid on the left (N-terminal side) of the first invariant His residues is assigned the number +6, and other amino acids further to the left are assigned successively decreasing numbers. The alpha helix begins at residue 1 and extends to the residue following the second conserved histidine. The entire helix is therefore of variable length, between 11 and 13 residues.
The process of designing or selecting a nonnaturally occurring or variant ZFP typically starts with a natural ZFP as a source of framework residues. The process of design or selection serves to define nonconserved positions (i.e., positions −1 to +6) so as to confer a desired binding specificity. One suitable ZFP is the DNA binding domain of the mouse transcription factor Zif268. The DNA binding domain of this protein has the amino acid sequence:
YACPVESCDRRFSRSDELTRHIRIHTGQKP (F1) (SEQ. ID No:9)
FQCRICMRNFSRSDHLTTHIRTHTGEKP (F2) (SEQ. ID. No:10)
FACDICGRKFARSDERKRHTKIHLRQK (F3) SEQ. ID. No:11)
and binds to a target 5′ GCG TGG GCG 3′ (SEQ ID No:12).
Another suitable natural zinc finger protein as a source of framework residues is Sp-1. The Sp-1 sequence used for construction of zinc finger proteins corresponds to amino acids 531 to 624 in the Sp-1 transcription factor. This sequence is 94 amino acids in length. The amino acid sequence of Sp-1 is as follows:
PGKKKQHICHIQGCGKVYGKTSHLRAHLRWHTGERP
FMCTWSYCGKRFTRSDELQRHKRTHTGEKK
FACPECPKRFMRSDHLSKHIKTHQNKKG (SEQ. ID. No:13)
Sp-1 binds to a target site 5′GGG GCG GGG3′ (SEQ ID No: 14).
An alternate form of Sp-1, an Sp-1 consensus sequence, has the following amino acid sequence:
meklrngsgd
PGKKKQHACPECGKSFSKSSHLRAHQRTHTGERP
YKCPECGKSFSRSDELQRHQRTHTGEKP
YKCPECGKSFSRSDHLSKHQRTHQNKKG (SEQ. ID. NO:15) (lower case letters are a leader sequence from Shi & Berg, Chemistry and Biology 1, 83-89. (1995). The optimal binding sequence for the Sp-1 consensus sequence is 5′GGGGCGGGG3′ (SEQ ID NO: 16). Other suitable ZFPs are described below.
There are a number of substitution rules that assist rational design of some zinc finger proteins (see Desjarlais & Berg, PNAS 90, 2256-2260 (1993); Choo & Klug, PNAS 91, 11163-11167 (1994); Desjarlais & Berg, PNAS 89, 7345-7349 (1992); Jamieson et al., supra; Choo et al., WO 98/53057, WO 98/53058; WO 98/53059; WO 98/53060). Many of these rules are supported by site-directed mutagenesis of the three-finger domain of the ubiquitous transcription factor, Sp-1 (Desjarlais and Berg, 1992; 1993). One of these rules is that a 5′ G in a DNA triplet can be bound by a zinc finger incorporating arginine at position 6 of the recognition helix. Another substitution rule is that a G in the middle of a subsite can be recognized by including a histidine residue at position 3 of a zinc finger. A further substitution rule is that asparagine can be incorporated to recognize A in the middle of triplet, aspartic acid, glutamic acid, serine or threonine can be incorporated to recognize C in the middle of triplet, and amino acids with small side chains such as alanine can be incorporated to recognize T in the middle of triplet. A further substitution rule is that the 3′ base of triplet subsite can be recognized by incorporating the following amino acids at position −1 of the recognition helix: arginine to recognize G, glutamine to recognize A, glutamic acid (or aspartic acid) to recognize C, and threonine to recognize T. Although these substitution rules are useful in designing zinc finger proteins they do not take into account all possible target sites. Furthermore, the assumption underlying the rules, namely that a particular amino acid in a zinc finger is responsible for binding to a particular base in a subsite is only approximate. Context-dependent interactions between proximate amino acids in a finger or binding of multiple amino acids to a single base or vice versa can cause variation of the binding specificities predicted by the existing substitution rules.
The technique of phage display provides a largely empirical means of generating zinc finger proteins with a desired target specificity (see e.g., Rebar, U.S. Pat. No. 5,789,538; Choo et al., WO 96/06166; Barbas et al., WO 95/19431 and WO 98/543111; Jamieson et al., supra). The method can be used in conjunction with, or as an alternative to rational design. The method involves the generation of diverse libraries of mutagenized zinc finger proteins, followed by the isolation of proteins with desired DNA-binding properties using affinity selection methods. To use this method, the experimenter typically proceeds as follows. First, a gene for a zinc finger protein is mutagenized to introduce diversity into regions important for binding specificity and/or affinity. In a typical application, this is accomplished via randomization of a single finger at positions −1, +2, +3, and +6, and sometimes accessory positions such as +1, +5, +8 and +10. Next, the mutagenized gene is cloned into a phage or phagemid vector as a fusion with gene III of a filamentous phage, which encodes the coat protein pIII. The zinc finger gene is inserted between segments of gene III encoding the membrane export signal peptide and the remainder of pIII, so that the zinc finger protein is expressed as an amino-terminal fusion with pIII or in the mature, processed protein. When using phagemid vectors, the mutagenized zinc finger gene may also be fused to a truncated version of gene III encoding, minimally, the C-terminal region required for assembly of pIII into the phage particle. The resultant vector library is transformed into E. coli and used to produce filamentous phage which express variant zinc finger proteins on their surface as fusions with the coat protein pIII. If a phagemid vector is used, then the this step requires superinfection with helper phage. The phage library is then incubated with target DNA site, and affinity selection methods are used to isolate phage which bind target with high affinity from bulk phage. Typically, the DNA target is immobilized on a solid support, which is then washed under conditions sufficient to remove all but the tightest binding phage. After washing, any phage remaining on the support are recovered via elution under conditions which disrupt zinc finger-DNA binding. Recovered phage are used to infect fresh E. coli., which is then amplified and used to produce a new batch of phage particles. Selection and amplification are then repeated as many times as is necessary to enrich the phage pool for tight binders such that these may be identified using sequencing and/or screening methods. Although the method is illustrated for pIII fusions, analogous principles can be used to screen ZFP variants as pVIII fusions.
In certain embodiments, the sequence bound by a particular zinc finger protein is determined by conducting binding reactions (see, e.g., conditions for determination of Kd, infra) between the protein and a pool of randomized double-stranded oligonucleotide sequences. The binding reaction is analyzed by an electrophoretic mobility shift assay (EMSA), in which protein-DNA complexes undergo retarded migration in a gel and can be separated from unbound nucleic acid. Oligonucleotides which have bound the finger are purified from the gel and amplified, for example, by a polymerase chain reaction. The selection (i.e. binding reaction and EMSA analysis) is then repeated as many times as desired, with the selected oligonucleotide sequences. In this way, the binding specificity of a zinc finger protein having a particular amino acid sequence is determined.
Zinc finger proteins are often expressed with a heterologous domain as fusion proteins. Common domains for addition to the ZFP include, e.g., transcription factor domains (activators, repressors, co-activators, co-repressors), silencers, oncogenes (e.g., myc, jun, fos, myb, max, mad, rel, ets, bcl, myb, mos family members etc.); DNA repair enzymes and their associated factors and modifiers; DNA rearrangement enzymes and their associated factors and modifiers; chromatin associated proteins and their modifiers (e.g. kinases, acetylases and deacetylases); and DNA modifying enzymes (e.g., methyltransferases, topoisomerases, helicases, ligases, kinases, phosphatases, polymerases, endonucleases) and their associated factors and modifiers. A preferred domain for fusing with a ZFP when the ZFP is to be used for repressing expression of a target gene is a KRAB repression domain from the human KOX-1 protein (Thiesen et al., New Biologist 2, 363-374 (1990); Margolin et al., Proc. Natl. Acad. Sci. USA 91, 4509-4513 (1994); Pengue et al., Nucl. Acids Res. 22:2908-2914 (1994); Witzgall et al., Proc. Natl. Acad. Sci. USA 91, 4514-4518 (1994). Preferred domains for achieving activation include the HSV VP16 activation domain (see, e.g., Hagmann et al., J. Virol. 71, 5952-5962 (1997)) nuclear hormone receptors (see, e.g., Torchia et al., Curr. Opin. Cell. Biol. 10:373-383 (1998)); the p65 subunit of nuclear factor kappa B (Bitko & Barik, J. Virol. 72:5610-5618 (1998) and Doyle & Hunt, Neuroreport 8:2937-2942 (1997)); Liu et al., Cancer Gene Ther. 5:3-28 (1998)), or artificial chimeric functional domains such as VP64 (Seifpal et al., EMBO J. 11, 4961-4968 (1992)).
An important factor in the administration of polypeptide compounds, such as the ZFPs, is ensuring that the polypeptide has the ability to traverse the plasma membrane of a cell, or the membrane of an intra-cellular compartment such as the nucleus. Cellular membranes are composed of lipid-protein bilayers that are freely permeable to small, nonionic lipophilic compounds and are inherently impermeable to polar compounds, macromolecules, and therapeutic or diagnostic agents. However, proteins and other compounds such as liposomes have been described, which have the ability to translocate polypeptides such as ZFPs across a cell membrane.
For example, “membrane translocation polypeptides” have amphiphilic or hydrophobic amino acid subsequences that have the ability to act as membrane-translocating carriers. In one embodiment, homeodomain proteins have the ability to translocate across cell membranes. The shortest internalizable peptide of a homeodomain protein, Antennapedia, was found to be the third helix of the protein, from amino acid position 43 to 58 (see, e.g., Prochiantz, Current Opinion in Neurobiology 6:629-634 (1996)). Another subsequence, the h (hydrophobic) domain of signal peptides, was found to have similar cell membrane translocation characteristics (see, e.g., Lin et al., J. Biol. Chem. 270:1 4255-14258 (1995)).
Examples of peptide sequences which can be linked to a ZFP, for facilitating uptake of ZFP into cells, include, but are not limited to: an 11 amino acid peptide of the tat protein of HIV; a 20 residue peptide sequence which corresponds to amino acids 84-103 of the p16 protein (see Fahraeus et al., Current Biology 6:84 (1996)); the third helix of the 60-amino acid long homeodomain of Antennapedia (Derossi et al., J. Biol. Chem. 269:10444 (1994)); the h region of a signal peptide such as the Kaposi fibroblast growth factor (K-FGF) h region (Lin et al., supra); or the VP22 translocation domain from HSV (Elliot & O'Hare, Cell 88:223-233 (1997)). Other suitable chemical moieties that provide enhanced cellular uptake may also be chemically linked to ZFPs.
Toxin molecules also have the ability to transport polypeptides across cell membranes. Often, such molecules are composed of at least two parts (called “binary toxins”): a translocation or binding domain or polypeptide and a separate toxin domain or polypeptide. Typically, the translocation domain or polypeptide binds to a cellular receptor, and then the toxin is transported into the cell. Several bacterial toxins, including Clostridium perfringens iota toxin, diphtheria toxin (DT), Pseudomonas exotoxin A (PE), pertussis toxin (PT), Bacillus anthracis toxin, and pertussis adenylate cyclase (CYA), have been used in attempts to deliver peptides to the cell cytosol as internal or amino-terminal fusions (Arora et al., J. Biol. Chem., 268:3334-3341 (1993); Perelle et al., Infect. Immun., 61:5147-5156 (1993); Stenmark et al., J. Cell Biol. 113:1025-1032 (1991); Donnelly et al., PNAS 90:3530-3534 (1993); Carbonetti et al., Abstr. Annu. Meet. Am. Soc. Microbiol. 95:295 (1995); Sebo et al., Infect. Immun. 63:3851-3857 (1995); Klimpel et al., PNAS U.S.A. 89:10277-10281 (1992); and Novak et al., J. Biol. Chem. 267:17186-17193 1992)).
Such subsequences can be used to translocate ZFPs across a cell membrane. ZFPs can be conveniently fused to or derivatized with such sequences. Typically, the translocation sequence is provided as part of a fusion protein. Optionally, a linker can be used to link the ZFP and the translocation sequence. Any suitable linker can be used, e.g., a peptide linker.
III. Position Dependence of Subsite Recognition by Zinc Fingers
A number of the polypeptides disclosed herein have been characterized using the methods disclosed in U.S. Pat. No. 6,794,136; which matured from a grandparent of the present application (the disclosure of which is hereby incorporated by reference in its entirety); in particular with respect to the effect of their position, within a multi-finger protein, on their sequence specificity. The results of these investigations provide a set of zinc finger sequences that are optimized for recognition of certain triplet target subsites whose 5′-most nucleotide is a G (i.e., GNN triplet subsites). Thus, particular zinc finger sequences which recognize each of the GNN triplet subsites, from each position of a three-finger zinc finger protein, are provided. See FIG. 2. It will be clear to those of skill in the art that the optimized, position-specific zinc finger sequences disclosed herein for recognition of GNN target subsites are not limited to use in three-finger proteins. For example, they are also useful in six-finger proteins, which can be made by linkage of two three-finger proteins.
A number of zinc finger amino acid sequences which are reported to bind to target subsites in which the 5′-most nucleotide residue is G (i.e., GNN subsites) have recently been disclosed. Segal et al. (1999) Proc. Natl. Acad. Sci. USA 96:2758-2763; Drier et al. (2000) J. Mol. Biol. 303:489-502; U.S. Pat. No. 6,140,081. These GNN-binding zinc fingers were obtained by selection of finger 2 sequences from phage display libraries of three-finger proteins, in which certain amino acid residues of finger 2 had been randomized. Due to the manner in which they were selected, it is not clear whether these sequences would have the same target subsite specificity if they were present in the F1 and/or F3 positions.
Use of the methods and compositions disclosed herein has now allowed identification of specific zinc finger sequences that bind each of the 16 GNN triplet subsites, and for the first time, provides zinc finger sequences that are optimized for recognition of these triplet subsites in a position-dependent fashion. Moreover, in vivo studies of these optimized designs reveal that the functionality of a ZFP is correlated with its binding affinity to its target sequence. See Example 6, infra.
As a result of the discovery, disclosed herein, that sequence recognition by zinc fingers is position-dependent, it is clear that existing design rules will not, in and of themselves, be applicable to every situation in which it is necessary to construct a sequence-specific ZFP. The results disclosed herein show that many zinc fingers that are constructed based on design rules exhibit the sequence specificity predicted by those design rules only at certain finger positions. The position-specific zinc fingers disclosed herein are likely to function more efficiently in vivo and in cultured cells, with fewer nonspecific effects. Highly specific ZFPs, made using position-specific zinc fingers, will be useful tools in studying gene function and will find broad applications in areas as diverse as human therapeutics and plant engineering.
IV. Production of Zinc Finger Proteins
ZFP polypeptides and nucleic acids encoding the same can be made using routine techniques in the field of recombinant genetics. Basic texts disclosing the general methods include Sambrook et al., Molecular Cloning, A Laboratory Manual (2nd ed. 1989); Kriegler, Gene Transfer and Expression: A Laboratory Manual (1990); and Current Protocols in Molecular Biology (Ausubel et al., eds., 1994)). In addition, nucleic acids less than about 100 bases can be custom ordered from any of a variety of commercial sources, such as The Midland Certified Reagent Company (mcrc@oligos.com), The Great American Gene Company (http://www.genco.com), ExpressGen Inc. (www.expressgen.com), Operon Technologies Inc. (Alameda, Calif.). Similarly, peptides can be custom ordered from any of a variety of sources, such as PeptidoGenic (pkim@ccnet.com), HTI Bio-products, inc. (http://www.htibio.com), BMA Biomedicals Ltd (U.K.), Bio.Synthesis, Inc.
Oligonucleotides can be chemically synthesized according to the solid phase phosphoramidite triester method first described by Beaucage & Caruthers, Tetrahedron Letts. 22:1859-1862 (1981), using an automated synthesizer, as described in Van Devanter et al., Nucleic Acids Res. 12:6159-6168 (1984). Purification of oligonucleotides is by either denaturing polyacrylamide gel electrophoresis or by reverse phase HPLC. The sequence of the cloned genes and synthetic oligonucleotides can be verified after cloning using, e.g., the chain termination method for sequencing double-stranded templates of Wallace et al., Gene 16:21-26 (1981).
Two alternative methods are typically used to create the coding sequences required to express newly designed DNA-binding peptides. One protocol is a PCR-based assembly procedure that utilizes six overlapping oligonucleotides (FIG. 1). Three oligonucleotides (oligos 1, 3, and 5 in FIG. 1) correspond to “universal” sequences that encode portions of the DNA-binding domain between the recognition helices. These oligonucleotides typically remain constant for all zinc finger constructs. The other three “specific” oligonucleotides (oligos 2, 4, and 6 in FIG. 1) are designed to encode the recognition helices. These oligonucleotides contain substitutions primarily at positions −1, 2, 3 and 6 on the recognition helices making them specific for each of the different DNA-binding domains.
The PCR synthesis is carried out in two steps. First, a double stranded DNA template is created by combining the six oligonucleotides (three universal, three specific) in a four cycle PCR reaction with a low temperature annealing step, thereby annealing the oligonucleotides to form a DNA “scaffold.” The gaps in the scaffold are filled in by high-fidelity thermostable polymerase, the combination of Taq and Pfu polymerases also suffices. In the second phase of construction, the zinc finger template is amplified by external primers designed to incorporate restriction sites at either end for cloning into a shuttle vector or directly into an expression vector.
An alternative method of cloning the newly designed DNA-binding proteins relies on annealing complementary oligonucleotides encoding the specific regions of the desired ZFP. This particular application requires that the oligonucleotides be phosphorylated prior to the final ligation step. This is usually performed before setting up the annealing reactions. In brief, the “universal” oligonucleotides encoding the constant regions of the proteins (oligos 1, 2 and 3 of above) are annealed with their complementary oligonucleotides. Additionally, the “specific” oligonucleotides encoding the finger recognition helices are annealed with their respective complementary oligonucleotides. These complementary oligos are designed to fill in the region which was previously filled in by polymerase in the above-mentioned protocol. The complementary oligos to the common oligos 1 and finger 3 are engineered to leave overhanging sequences specific for the restriction sites used in cloning into the vector of choice in the following step. The second assembly protocol differs from the initial protocol in the following aspects: the “scaffold” encoding the newly designed ZFP is composed entirely of synthetic DNA thereby eliminating the polymerase fill-in step, additionally the fragment to be cloned into the vector does not require amplification. Lastly, the design of leaving sequence-specific overhangs eliminates the need for restriction enzyme digests of the inserting fragment. Alternatively, changes to ZFP recognition helices can be created using conventional site-directed mutagenesis methods.
Both assembly methods require that the resulting fragment encoding the newly designed ZFP be ligated into a vector. Ultimately, the ZFP-encoding sequence is cloned into an expression vector. Expression vectors that are commonly utilized include, but are not limited to, a modified pMAL-c2 bacterial expression vector (New England BioLabs or an eukaryotic expression vector, pcDNA (Promega). The final constructs are verified by sequence analysis.
Any suitable method of protein purification known to those of skill in the art can be used to purify ZFPs (see, Ausubel, supra, Sambrook, supra). In addition, any suitable host can be used for expression, e.g., bacterial cells, insect cells, yeast cells, mammalian cells, and the like.
Expression of a zinc finger protein fused to a maltose binding protein (MBP-ZFP) in bacterial strain JM109 allows for straightforward purification through an amylose column (NEB). High expression levels of the zinc finger chimeric protein can be obtained by induction with IPTG since the MBP-ZFP fusion in the pMal-c2 expression plasmid is under the control of the tac promoter (NEB). Bacteria containing the MBP-ZFP fusion plasmids are inoculated into 2×YT medium containing 10 μM ZnCl2, 0.02% glucose, plus 50 μg/ml ampicillin and shaken at 37° C. At mid-exponential growth IPTG is added to 0.3 mM and the cultures are allowed to shake. After 3 hours the bacteria are harvested by centrifugation, disrupted by sonication or by passage through a french pressure cell or through the use of lysozyme, and insoluble material is removed by centrifugation. The MBP-ZFP proteins are captured on an amylose-bound resin, washed extensively with buffer containing 20 mM Tris-HCl (pH 7.5), 200 mM NaCl, 5 mM DTT and 50 μM ZnCl2, then eluted with maltose in essentially the same buffer (purification is based on a standard protocol from NEB). Purified proteins are quantitated and stored for biochemical analysis.
The dissociation constants of the purified proteins, e.g., Kd, are typically characterized via electrophoretic mobility shift assays (EMSA) (Buratowski & Chodosh, in Current Protocols in Molecular Biology pp. 12.2.1-12.2.7 (Ausubel ed., 1996)). Affinity is measured by titrating purified protein against a fixed amount of labeled double-stranded oligonucleotide target. The target typically comprises the natural binding site sequence flanked by the 3 bp found in the natural sequence and additional, constant flanking sequences. The natural binding site is typically 9 bp for a three-finger protein and 2×9 bp+intervening bases for a six finger ZFP. The annealed oligonucleotide targets possess a 1 base 5′ overhang which allows for efficient labeling of the target with T4 phage polynucleotide kinase. For the assay the target is added at a concentration of 1 nM or lower (the actual concentration is kept at least 10-fold lower than the expected dissociation constant), purified ZFPs are added at various concentrations, and the reaction is allowed to equilibrate for at least 45 min. In addition the reaction mixture also contains 10 mM Tris (pH 7.5), 100 mM KCl, 1 mM MgCl2, 0.1 mM ZnCl2, 5 mM DTT, 10% glycerol, 0.02% BSA. (NB: in earlier assays poly d(IC) was also added at 10-100 μg/μl.)
The equilibrated reactions are loaded onto a 10% polyacrylamide gel, which has been pre-run for 45 min in Tris/glycine buffer, then bound and unbound labeled target is resolved by electrophoresis at 150V. (alternatively, 10-20% gradient Tris-HCl gels, containing a 4% polyacrylamide stacker, can be used) The dried gels are visualized by autoradiography or phosphorimaging and the apparent Kd is determined by calculating the protein concentration that gives half-maximal binding.
The assays can also include determining active fractions in the protein preparations. Active fractions are determined by stoichiometric gel shifts where proteins are titrated against a high concentration of target DNA. Titrations are done at 100, 50, and 25% of target (usually at micromolar levels).
V. Applications of Engineered Zinc Finger Proteins
ZPFs that bind to a particular target gene, and the nucleic acids encoding them, can be used for a variety of applications. These applications include therapeutic methods in which a ZFP or a nucleic acid encoding it is administered to a subject and used to modulate the expression of a target gene within the subject. See, for example, co-owned WO 00/41566. The modulation can be in the form of repression, for example, when the target gene resides in a pathological infecting microrganisms, or in an endogenous gene of the patient, such as an oncogene or viral receptor, that is contributing to a disease state. Alternatively, the modulation can be in the form of activation when activation of expression or increased expression of an endogenous cellular gene can ameliorate a diseased state. For such applications, ZFPs, or more typically, nucleic acids encoding them are formulated with a pharmaceutically acceptable carrier as a pharmaceutical composition.
Pharmaceutically acceptable carriers are determined in part by the particular composition being administered, as well as by the particular method used to administer the composition. (see, e.g., Remington's Pharmaceutical Sciences, 17th ed. 1985)). The ZFPs, alone or in combination with other suitable components, can be made into aerosol formulations (i.e., they can be “nebulized”) to be administered via inhalation. Aerosol formulations can be placed into pressurized acceptable propellants, such as dichlorodifluoromethane, propane, nitrogen, and the like. Formulations suitable for parenteral administration, such as, for example, by intravenous, intramuscular, intradermal, and subcutaneous routes, include aqueous and non-aqueous, isotonic sterile injection solutions, which can contain antioxidants, buffers, bacteriostats, and solutes that render the formulation isotonic with the blood of the intended recipient, and aqueous and non-aqueous sterile suspensions that can include suspending agents, solubilizers, thickening agents, stabilizers, and preservatives. Compositions can be administered, for example, by intravenous infusion, orally, topically, intraperitoneally, intravesically or intrathecally. The formulations of compounds can be presented in unit-dose or multi-dose sealed containers, such as ampules and vials. Injection solutions and suspensions can be prepared from sterile powders, granules, and tablets of the kind previously described.
The dose administered to a patient should be sufficient to effect a beneficial therapeutic response in the patient over time. The dose is determined by the efficacy and Kd, of the particular ZFP employed, the target cell, and the condition of the patient, as well as the body weight or surface area of the patient to be treated. The size of the dose also is determined by the existence, nature, and extent of any adverse side-effects that accompany the administration of a particular compound or vector in a particular patient.
In other applications, ZFPs are used in diagnostic methods for sequence specific detection of target nucleic acid in a sample. For example, ZFPs can be used to detect variant alleles associated with a disease or phenotype in patient samples. As an example, ZFPs can be used to detect the presence of particular mRNA species or cDNA in a complex mixtures of mRNAs or cDNAs. As a further example, ZFPs can be used to quantify copy number of a gene in a sample. For example, detection of loss of one copy of a p53 gene in a clinical sample is an indicator of susceptibility to cancer. In a further example, ZFPs are used to detect the presence of pathological microorganisms in clinical samples. This is achieved by using one or more ZFPs specific to genes within the microorganism to be detected. A suitable format for performing diagnostic assays employs ZFPs linked to a domain that allows immobilization of the ZFP on an ELISA plate. The immobilized ZFP is contacted with a sample suspected of containing a target nucleic acid under conditions in which binding can occur. Typically, nucleic acids in the sample are labeled (e.g., in the course of PCR amplification). Alternatively, unlabelled probes can be detected using a second labelled probe. After washing, bound-labelled nucleic acids are detected.
ZFPs also can be used for assays to determine the phenotype and function of gene expression. Current methodologies for determination of gene function rely primarily upon either overexpression or removing (knocking out completely) the gene of interest from its natural biological setting and observing the effects. The phenotypic effects observed indicate the role of the gene in the biological system.
One advantage of ZFP-mediated regulation of a gene relative to conventional knockout analysis is that expression of the ZFP can be placed under small molecule control. By controlling expression levels of the ZFPs, one can in turn control the expression levels of a gene regulated by the ZFP to determine what degree of repression or stimulation of expression is required to achieve a given phenotypic or biochemical effect. This approach has particular value for drug development. By putting the ZFP under small molecule control, problems of embryonic lethality and developmental compensation can be avoided by switching on the ZFP repressor at a later stage in mouse development and observing the effects in the adult animal. Transgenic mice having target genes regulated by a ZFP can be produced by integration of the nucleic acid encoding the ZFP at any site in trans to the target gene. Accordingly, homologous recombination is not required for integration of the nucleic acid. Further, because the ZFP is trans-dominant, only one chromosomal copy is needed and therefore functional knock-out animals can be produced without backcrossing.

Example 1
Initial Design of Zinc Finger Proteins and Determination of Binding Affinity
Initial ZFP designs were based on existing design rules, correspondence regimes and ZFP directories, including those disclosed herein (see Tables 1-5) and also in WO 98/53058; WO 98/530059; WO 98/53060 and co-owned U.S. patent application Ser. No. 09/444,241. See also WO 00/42219 Amino acid sequences were conceptually designed using amino acids 532-624 of the human transcription factor Sp1 as a backbone. Polynucleotides encoding designed ZFPs were assembled using a Polymerase Chain Reaction (PCR)-based procedure that utilizes six overlapping oligonucleotides. PCR products were directly cloned cloning into the Tac promoter vector, pMal-c2 (New England Biolabs, Beverly, Mass.) using the KpnI and BamHI restriction sites. The encoded maltose binding protein-ZFP fusion polypeptides were purified according to the manufacturer's procedures (New England Biolabs, Beverly, Mass.). Binding affinity was measured by gel mobility-shift analysis. All of these procedures are described in detail in co-owned WO 00/41566 and WO 00/42219, as well as in Zhang et al. (2000) J. Biol. Chem. 275:33,850-33,860 and Liu et al. (2001) J. Biol. Chem. 276:11,323-11,334; the disclosures of which are hereby incorporated by reference in their entireties.
Example 2
Optimization of Binding Specificity by Site Selection
Designed ZFPs were tested for binding specificity using site selection methods disclosed in parent application U.S. Ser. No. 09/716,637 filed Nov. 20, 2000, now U.S. Pat. No. 6,794,136. Briefly, designed proteins were incubated with a population of labeled, double-stranded oligonucleotides comprising a library of all possible 9- or 10-nucleotide target sequences. Five nanomoles of labeled oligonucleotides were incubated with protein, at a protein concentration 4-fold above its Kd for its target sequence. The mixture was subjected to gel electrophoresis, and bound oligonucleotides were identified by mobility shift, and extracted from the gel. The purified bound oligonucleotides were amplified, and the amplification products were used for a subsequent round of selection. At each round of selection, the protein concentration was decreased by 2 fold. After 3-5 rounds of selection, amplification products were cloned into the TOPO TA cloning vector (Invitrogen, Carlsbad, Calif.), and the nucleotide sequences of approximately 20 clones were determined. The identities of the target sites bound by a designed protein were determined from the sequences and expressed as a compilation of subsite binding sequences.
Example 3
Comparison of Site Selection Results with Binding Affinity
To test the correlation between site selection results and the affinity of binding of a ZFP to various related targets, site selection experiments were conducted on 2 three-finger ZFPs, denoted ZFP1 and ZFP2, and the site selection results were compared with Kd measurements obtained from quantitative gel-mobility shift assays using the same ZFPs and target sites. Each ZFP was constructed, based on design rules, to bind to a particular nine-nucleotide target sequence (comprising 3 three-nucleotide subsites), as shown in FIG. 1. Site selection results and affinity measurements are also shown in FIG. 1. The site selection results showed that fingers 1 and 3 of both the ZFP1 and ZFP2 proteins preferentially selected their intended target sequences. However, the second finger of each ZFP preferentially selected subsites other than those to which they were designed to bind (e.g., F2 of ZFP1 was designed to bind TCG, but preferentially selected GTG; F2 of ZFP2 was designed to bind GGT, but preferentially selected GGA).
To confirm the site selection results, binding affinities of ZFP1 and ZFP2 were measured (see Example 1, supra), both to their original target sequences and to new target sequences reflecting the site selection results. For example, the Mt-1 sequence contains two base changes (compared to the original target sequence for ZFP1) which result in a change in the sequence of the finger 2 subsite to GTG, reflecting the preferred finger 2 subsite sequence obtained by site selection. In agreement with the site selection results, binding of ZFP1 to the Mt-1 sequence is approximately 4-fold stronger than its binding to the original target sequence (Kd of 12.5 nM compared to a Kd of 50 nM, see FIG. 1).
For ZFP2, the specificity of finger 2 for the 3′ base of its target subsite was tested, since, although this finger was designed to bind GGT, site selection indicated that it bound preferentially to GGA. Moreover, the site selection results predicted that finger 2 of ZFP2 would bind with approximately equal affinity to GGT and GGC. Accordingly, target sequences containing GGA (Mt-3) and GGC (Mt-4) at the finger 2 subsite were constructed, and binding affinities of ZFP2 to these target sequences, and to its original target sequence (containing GGT at the finger 2 subsite), were compared. In complete agreement with the site selection results, ZFP2 exhibited the strongest binding affinity for the target sequence containing GGA at the finger 2 subsite (Kd of 0.5 nM, FIG. 1), and its affinity for target sequences containing either GGT or GGC at the finger 2 subsite was approximately equal (Kd of 1 nM for both targets, FIG. 1). Accordingly, the site selection method, in addition to being useful for iterative optimization of binding specificity, can also be used as a useful indicator of binding affinity.
Example 4
Use of Site Selection to Identify Position-Dependent, GNN-Binding Zinc Fingers
A large number of engineered ZFPs have been evaluated, by site selection, to identify zinc fingers that bind to GNN target subsites. In the course of these studies, it became apparent that the binding specificity of a particular zinc finger sequence is, in some instances, dependent upon the position of the zinc finger in the protein, and hence upon the location of the target subsite within the target sequence. For example, if one wishes to design a three-finger zinc finger protein to bind to a target sequence containing the triplet subsite GAT, it is necessary to know whether this subsite is the first, second or third subsite in the target sequence (i.e., whether the GAT subsite will be bound by the first, second or third finger of the protein). Accordingly, over 110 three-finger zinc finger proteins, containing potential GNN-recognizing zinc fingers in various locations, have been evaluated by site selection experiments. Generally, several zinc finger sequences were designed to recognize each GNN triplet, and each design was tested in each of the F1, F2 and F3 positions through 4 to 6 rounds of selection.
The results of these analyses, shown in FIG. 2, provide optimal position-dependent zinc finger sequences (the sequences shown represent amino acid residues −1 through +6 of the recognition helix portion of the finger) for recognition of the 16 GNN target subsites, as well as site selection results for these GNN-specific zinc fingers. Optimal amino acid sequences for recognition of each GNN subsite from each of three positions (finger 1, finger 2 or finger 3) are thereby provided.
GNG-Binding Finger Designs
The amino acid sequence RSDXLXR (SEQ ID NO:4085) (position −1 to +6 of the recognition helix) was found to be optimal for binding to the four GNG triplets, with Asn+3 specifying A as the middle nucleotide; His+3 specifying G as the middle nucleotide; Ala+3 specifying T as the middle nucleotide; and Asp+3 specifying cytosine as the middle nucleotide. At the +5 position, Ala, Thr, Ser, and Gln, were tested, and all showed similar specificity profiles by site selection. Interestingly, and in contrast to a previous report (Swirnoff et al. (1995) Mol. Cell. Biol. 15:2275-2287), site selection results indicated that three naturally-occurring GCG-binding fingers from zif268 and Sp1, having the amino acid sequences RSDELTR (SEQ ID NO:123), RSDELQR (SEQ ID NO:302), and RSDERKR (SEQ ID NO:1100), were not GCG-specific. Rather, each of these fingers selected almost equal numbers of GCG and GTG sequences. Analysis of binding affinity by gel-shift experiments confirmed that finger 3 of zif268, having the sequence RSDERKR (SEQ ID NO:1000), binds GCG and GTG with approximately equal affinity.
Position Dependence of GCA-, GAT-, GGT-, GAA- and GCC-Binding Fingers
Based on existing design rules, the amino acid sequence QSGDLTR (SEQ ID NO:220) (−1 through +6) was tested for its ability to bind the GCA triplet from three positions (F1, F2, and F3) within a three-finger ZFP. FIG. 3A shows that the QSGDLTR (SEQ ID NO:220) sequence bound preferentially to the GCA triplet subsite from the F2 and F3 positions, but not from F1. In fact, the presence of QSGDLTR (SEQ ID NO:220) at the F1 position of three different three-finger ZFPs resulted predominantly in selection of GCT. Accordingly, an attempt was made to redesign this sequence to obtain specificity for GCA from the F1 position. Since the sequence Q−1G+2S+3R+6 (SEQ ID NO:4065) had previously been selected from a randomized F1 library using GCA as target (Rebar et al. (1994) Science 263:671-673), a D (asp) to S (ser) change was made at the +3 residue of this finger. The resulting sequence, QSGSLTR (SEQ ID NO:342), was tested for its binding specificity by site selection and found to preferentially bind GCA, from the F1 position, in three different ZFPs (see FIG. 2).
The QSGSLTR (SEQ ID NO:342) zinc finger, optimized for recognition of the GCA subsite from the F1 position, was tested for its selectivity when located at the F2 position. Accordingly, two ZFPs, one containing QSGSLTR (SEQ ID NO:342) at finger 2 and one containing QSGDLTR (SEQ ID NO:220) at finger 2 (both having identical F1 sequences and identical F3 sequences) were tested by site selection. The results indicated that, when used at the F2 position, QSGSLTR (SEQ ID NO:342) bound preferentially to GTA, rather than GCA. Thus, for optimal binding of a GCA triplet subsite from the F1 position, the amino acid sequence QSGSLTR (SEQ ID NO:342) is required; while, for optimal binding of the same subsite sequence from F2 or F3, QSGDLTR (SEQ ID NO:220) should be used. Accordingly, different zinc finger amino acid sequences may be needed to specify a particular triplet subsite sequence, depending upon the location of the subsite within the target sequence and, hence, upon the position of the finger in the protein.
Positional effects were also observed for zinc fingers recognizing GAT and GGT subsites. The zinc finger amino acid sequence QSSNLAR (SEQ ID NO:1765) (−1 through +6) is expected to bind to GAT, based on design rules. However, this sequence selected GAT only from the F1 position, and not from the F2 and F3 positions, from which the sequence GAA was preferentially bound (FIG. 3B). Similarly, the amino acid sequence QSSHLTR (SEQ ID NO:835) which, based on design rules, should bind GGT, selected GGT at the F1 position, but not at the F2 and F3 positions, from which it preferentially bound GGA (FIG. 3C). Conversely, the amino acid sequence TSGHLVR (SEQ ID NO:1425) has previously been disclosed to recognize the triplet GGT, based on its selection from a randomized library of zif268 finger 2. U.S. Pat. No. 6,140,081. However, TSGHLVR (SEQ ID NO:1425) was not specific for the GGT subsite when located at the F1 position (FIG. 3C). These results indicate that the binding specificity of many fingers is position dependent, and particularly point out that the sequence specificity of a zinc finger selected from a F2 library may be positionally limited.
The results shown in FIG. 2 indicate that recognition of at least GAA and GCC triplets by zinc fingers is also position dependent.
These positional dependences stand in contrast to earlier published work, which suggested that zinc fingers behaved as independent modules with respect to the sequence specificity of their binding to DNA. Desjarlais et al. (1993) Proc. Natl. Acad. Sci. USA 90:2256-2260.
Example 5
Characterization of EP2C
The engineered zinc finger protein EP2C binds to a target sequence, GCGGTGGCT with a dissociation constant (Kd) of 2 nM. Site selection results indicated that fingers 1 and 2 are highly specific for their target subsites, while finger 3 selects GCG (its intended target subsite) and GTG at approximately equal frequencies (FIG. 4A). To confirm these observations, the binding affinities of EP2C to its cognate target sequence, and to variant target sequences, was measured by standard gel-shift analyses (see Example 1, supra). As standards for comparison, the binding affinities of Sp1 and zif268 to their respective targets were also measured under the same conditions, and were determined to be 40 nM for SP1 (target sequence GGGGCGGGG) and 2 nM for zif268 (target sequence GCGTGGGCG). Measurements of binding affinities confirmed that F3 of EP2C bound GTG and GCG equally well (Kds of 2 nM), but bound GAG with a two-fold lower affinity (FIG. 4B). Finger 2 was very specific for the GTG triplet, binding 15-fold less tightly to a GGG triplet (compare 2C0 and 2C3 in FIG. 4B). Finger 1 was also very specific for the GCT triplet, it bound with 4-fold lower affinity to a GAT triplet (2C4) and with 2-fold lower affinity to a GCG triplet (2C5). This example shows, once again, the high degree of correlation between site selection results and binding affinities.
Example 6
Evaluation of Engineered ZFPs by In Vivo Functional Assays
To determine whether a correlation exists between the binding affinity of a engineered ZFP to its target sequence and its functionality in vivo, cell-based reporter gene assays were used to analyze the functional properties of the engineered ZFP EP2C (see Example 5, supra). For these assays, a plasmid encoding the EP2C ZFP, fused to a VP16 transcriptional activation domain, was used to construct a stable cell line (T-Rex-293TM, Invitrogen, Carlsbad, Calif.) in which expression of EP2C-VP16 is inducible, as described in Zhang et al., supra. To generate reporter constructs, three tandem copies of the EP2C target site, or its variants (see FIG. 4B, column 2), were inserted between the Mlu I and BglII sites of the pGL3 luciferase-encoding vector (Promega, Madison, Wis.), upstream of the SV40 promoter. Structures of all reporter constructs were confirmed by DNA sequencing.
Luciferase reporter assays were performed by co-transfection of luciferase reporter construct (200 ng) and pCMV-βgal (100 ng, used as an internal control) into the EP2C cells seeded in 6-well plates. Expression of the EP2C-VP16 transcriptional activator was induced with doxycycline (0.05 ug/ml) 24 h after transfection of reporter constructs. Cell lysates were harvested 40 hours post-transfection, luciferase and β-galactosidase activities were measured by the Dual-Light Reporter Assay System (Tropix, Bedford, Mass.), and luciferase activities were normalized to the co-transfected β-galactosidase activities. The results, shown on the right side of FIG. 4B, showed that the normalized luciferase activity for each reporter construct was well correlated with the in vitro binding affinity of EP2C to the target sequence present in the construct. For example, the target sequences to which EP2C bound with greatest affinity (2C0 and 2C2, Kd of 2 nM for each) both stimulated the highest levels of luciferase activity, when used to drive luciferase expression in the reporter construct (FIG. 4B). Target sequences to which EP2C bound with 2-fold lower affinity, 2C1 and 2C5 (Kd of 4 nM for each), stimulated roughly half the luciferase activity of the 2C0 and 2C2 targets. The 2C3 and 2C4 sequences, for which EP2C showed the lowest in vitro binding affinities, also yielded the lowest levels of in vivo activity when used to drive luciferase expression. Target 3B, a sequence to which EP2C does not bind, yielded background levels of luciferase activity, similar to those obtained with a luciferase-encoding vector lacking EP2C target sequences (pGL3). Thus there exist good correlations between binding affinity (as determined by Kd measurement), binding specificity (as determined by site selection) and in vivo functionality for engineered zinc finger proteins.

## Claims

1. A polynucleotide encoding a zinc finger protein that binds to a target site in a gene in a position-specific fashion, the target site comprising, in a 3′ to 5′ direction, first (S1), second (S2) and third (S3) target subsites, each target subsite having the nucleotide sequence GNN, the zinc finger protein comprising:
(a) a non-naturally-occurring zinc finger protein that has been engineered to bind the target site; and
(b) first (F1), second (F2) and third (F3) zinc fingers ordered F1, F2, F3 from N-terminus to C-terminus that bind to S1, S2 and S3, wherein:
if S1 comprises GGA, F1 comprises the amino acid sequence QSGHLAR (SEQ ID NO:413);
if S2 comprises GGT, F2 comprises the amino acid sequence TSGHLSR (SEQ ID NO:1201);
if S2 comprises GCA, F2 comprises QSGDLTR (SEQ ID NO:220);
if S2 comprises GCC, F2 comprises the amino acid sequence DRSDLTR (SEQ ID NO:417);
if S3 comprises GAT, F3 comprises the amino acid sequence TSANLSR (SEQ ID NO:377);
if S3 comprises GCA, F3 comprises QSGDLTR (SEQ ID NO:220);
if S3 comprises GCC, F3 comprises the amino acid sequence DRSDLTR (SEQ ID NO:417);
if S3 comprises GCT, F3 comprises the amino acid sequence QSSDLQR (SEQ ID NO:132);
and further wherein the zinc finger protein binds to the target site, thereby modulating expression of the gene.

2. The polynucleotide of claim 1, wherein said zinc finger protein further comprising a regulatory domain.
