Design, construction and in vitro testing of zinc finger ...

Zinc finger nucleases (ZFNs) are hybrid proteins that have been developed as targetable cleavage reagents for double-stranded DNA, both in vitro and in vivo. This protocol describes the design and construction of new DNA-binding domains comprised of zinc fingers (ZFs) directed at selected DNA sequen …

What history tells us XLIV: The construction of the zinc ...

The name 'zinc finger' came from the existence in these proteins of short sequences of amino acids that bind a zinc atom and are viewed as fingers sensing the DNA molecule. The latter motif was of a particular interest. It was described early (Miller et al. 1985) and corresponded to a huge family of DNA-binding proteins.

Zinc finger - Wikipedia

A zinc finger is a small protein structural motif that is characterized by the coordination of one or more zinc ions (Zn 2+) in order to stabilize the fold.It was originally coined to describe the finger-like appearance of a hypothesized structure from the African clawed frog (Xenopus laevis) transcription factor IIIA.However, it has been found to encompass a wide variety of differing …

Zinc Finger Library Construction - Creative Biolabs

The zinc finger scaffold libraries can be constructed through phage display technology by substitutions of five amino acids in the α-helical portion. Then the zinc finger scaffold with great specificity and affinity can be selected that carries various therapeutic and research capacities.

ZFN, TALEN and CRISPR/Cas-based methods for genome …

Engineered zinc-fingers are also available commercially; Sangamo Biosciences (Richmond, CA) has developed a propriety platform (CompoZr) for zinc-finger construction in partnership with Sigma-Aldrich (St. Louis, MO), allowing investigators to bypass zinc-finger construction and validation altogether and many thousands of proteins are already ...

Construction and Evaluation of Zinc Finger Nucleases

Zinc-finger nucleases (ZFNs) are programmable nucleases that have opened the door to the genome editing era. The construction of ZFNs recognizing a target sequence of interest is laborious, and has not been widely used recently. However, key ZFN patents are expiring over the next 2-4 years, enabling …

Zinc Finger - an overview | ScienceDirect Topics

M. Isalan, in Encyclopedia of Biological Chemistry (Second Edition), 2013 Evolution. Zinc fingers may have evolved originally from peptides, which maintained a simple ββα structure (similar to that shown in Figure 1(b)) independently of zinc.In any case, the ββα fold is one of the smallest possible units of protein tertiary structure, and may therefore be one of the oldest.

Zinc Finger Folding Activity - CBM

The construction of a physical model of the 3D structure of a zinc finger serves as a good example of how Toobers can be used to model protein structures. This kit is based on 1ZAA.pdb and represents amino acids 4- 31. Zinc Finger Folding Activity Based on amino acids 4 …

Identification and network construction of zinc finger ...

Zinc finger protein (ZFP) identified as it contains a repeated motif of "zinc finger" (Miller et al., 1985). The term "zinc finger" refers to a sequence of protein motif that is able to bind to a zinc ion by Cysteine (Cys) and Histidine (His) in order to stabilize its three-dimensional structure (Takatsuji, 1998).

Repeatable Construction Method for Engineered Zinc Finger ...

Zinc finger nuclease (ZFN) is a useful tool for endogenous site-directed genome modification. The development of an easier, less expensive and repeatedly usable construction method for various sequences of ZFNs should contribute to the further widespread use of this technology. Here, we establish a novel construction method for ZFNs. Zinc finger (ZF) …

Genome Engineering With Zinc-Finger Nucleases

The most useful of these was a set of Cys 2 His 2 zinc fingers (ZFs) in which each unit of ∼30 amino acids bound a single atom of zinc. The crystal structure of a set of three fingers bound to DNA showed that each finger contacts primarily 3 bp of DNA in remarkably modular fashion ( Pavletich and Pabo 1991 ).
