A method is described for selecting DNA-binding proteins that recognize desired sequences. The protocol involves gradually extending a new zinc finger protein across the desired 9- or 10-base pair target site, adding and optimizing one finger at a time. This procedure was tested with a TATA box, a p53 binding site, and a nuclear receptor element, and proteins were obtained that bind with nanomolar dissociation constants and discriminate effectively (greater than 20,000-fold) against nonspecific…

A rapid, generally applicable method to engineer zinc fingers illustrated by targeting the HIV-1 promoter
A rapid and convenient method that can be used to design zinc finger proteins against a variety of DNA-binding sites and yields proteins that bind sequence-specifically to DNA with Kd values in the nanomolar range is presented.
Profiling the DNA-binding specificities of engineered Cys2His2 zinc finger domains using a rapid cell-based method
The development of a specificity profiling system that facilitates rapid and inexpensive characterization of engineered zinc-finger modules and it is demonstrated that specificity data collected using this system can be employed to rationally design zinc fingers with improved DNA-binding specificities.
Directed evolution of ATP binding proteins from a zinc finger domain by using mRNA display.
A combinatorial library based on the DNA binding domain of the human retinoid-X-receptor (hRXRalpha) is designed, demonstrating a significant alteration of the function of this protein domain from DNA binding to ATP recognition.
Design of novel sequence-specific DNA-binding proteins.
It appears that it is possible to produce proteins capable of targeting any gene with an 18 base pair recognition domain, and will probably find diverse applications in gene therapy, functional genomics, and agriculture.
Re-programming DNA-binding specificity in zinc finger proteins for targeting unique address in a genome
The novel functionality obtained by engineered zinc Finger proteins and the computational approaches for prediction of recognition helices of zinc finger proteins that can raise the ability to re-program zinc finger protein with desired novel DNA-binding specificities are explored.
Structure of Aart, a designed six-finger zinc finger peptide, bound to DNA.
This is the first structure of a designed protein with six fingers, and was intended to provide insights into the unusual affinity and specificity characteristics of this protein, which challenges some conventional concepts of recognition.
Structure based design of protein linkers for zinc finger nuclease
An extensive library of possible linker molecules between individual zinc finger motifs in the construct is provided that can skip up to 10 base pairs between adjacent zinc finger recognition sites in the DNA sequence, which increases the number of genes that can be efficiently targeted by more than an order of magnitude.
DNA-binding specificity is a major determinant of the activity and toxicity of zinc-finger nucleases.
The results of these cell-based assays reveal that the DNA-binding specificity--in addition to the affinity--is a major determinant of ZFN activity and is inversely correlated with ZFN-associated toxicity, and provide the first evidence that engineering strategies, which account for context-dependent DNA- binding effects, yield ZFs that function as highly efficient ZFNs in human cells.
High-resolution structures of variant Zif268-DNA complexes: implications for understanding zinc finger-DNA recognition.
The X-ray crystal structures of zinc finger-DNA complexes involving three variants of Zif268 show how modest changes in the docking arrangement accommodate the new sidechain-base and side chain-phosphate interactions, and help explain the versatility of naturally occurring zinc finger proteins and their utility in design.
DNA Recognition/Processing | Zinc Fingers: Structure and Design
Abstract Zinc fingers are small, compact protein subunits, folding around chelated zinc ions. Functionally, these motifs carry out a wide variety of tasks within cells by providing stable structural
