Each zinc finger module binds with a nucleotide triplet, whereas TALEN subunits interact with single base pairs. We have ZFN available to target practically all possible nucleotide triplets, albeit individual zinc fingers can display context-dependent effects.
The zinc finger domain enables different proteins to interact with or bind DNA, RNA, or other proteins, and is present in the proteomes of many different organisms.

Overlapping of different zinc ‘finger’ motifs. Searches with the C2H2ori and C2H2new motifs may lead in some cases to detection of questionable or even wrong fingers with sequences significantly deviating from a finger consensus. Compared with the C2H2ori motif the C2H2new pattern detects many more ‘bad’ fingers.

Zinc fingers perform many different jobs, as shown in these three sample structures. The complex at upper left (PDB entry 1y0j ) shows zinc fingers from two longer proteins, GATA-1 (which contains two zinc fingers) and FOG-1 (which contains 9 zinc fingers).
Zinc fingers are structurally diverse and are present among proteins that perform a broad range of functions in various cellular processes, such as replication and repair, transcription and translation, metabolism and signaling, cell proliferation and apoptosis.
Zinc-finger proteins can each bind to about three DNA bases, which means researchers can use various combinations of them to precisely target and bind to different DNA sequences. For example, combining six zinc fingers allows the targeting of …

Dec 29, 2009· The Zinc Finger Consortium, founded by Dr. Joung and Dr. Voytas, makes the method available free, and researchers need only pay for materials. But there are some 200 steps in Dr. Joung’s recipe for making zinc fingers, and it takes time and dedication to do them all correctly. The alternative is to buy zinc fingers.

Zinc-finger nucleases (ZFNs) are targetable DNA cleavage reagents that have been adopted as gene-targeting tools. ZFN-induced double-strand breaks are subject to cellular DNA repair processes that lead to both targeted mutagenesis and targeted gene replacement at remarkably high frequencies.
The RING-finger is a specialised type of Zn-finger of 40 to 60 residues that binds two atoms of zinc, and is probably involved in mediating protein-protein interactions [PMID: 8317827, PMID: 8804826, PMID: 8744354].

Zinc-finger nucleases (ZFNs) are artificial restriction enzymes generated by fusing a zinc finger DNA-binding domain to a DNA-cleavage domain. Zinc finger domains can be engineered to target specific desired DNA sequences and this enables zinc-finger nucleases to target unique sequences within complex genomes.
Normally, zinc fingers bind to different bases in the DNA sequence to regulate the activity of genes. The zinc fingers used in this experiment were designed to bind ...
Zinc Fingers By Jennifer McDowall Protein-protein and protein-nucleic acid interactions are essential functions of many proteins. Proteins have developed different ways to bind other molecules. Zinc-binding repeats, known as zinc fingers (ZnF), are one such molecular scaffold.
Zinc finger Zinc fingers are structural elements of proteins in which tertiary structure is stabilized by coordination of a single Zn2+ ion by four nucleophilic amino acids (typically cysteine, histidine, glutamate, or aspartate) [156].
Zinc finger containing domains typically serve as interactors, binding DNA, RNA, proteins or small molecules (Laity et al., 2001). ZnF Protein Families Cys 2 His 2 was the first …
Zinc-Finger Nucleases. Zinc-finger nucleases (ZFNs) technology allows the rapid and targeted modification of the rat genome. ZFNs are artificial restriction enzymes, which are generated by fusing zinc finger DNA-binding domain to a DNA-cleavage domain.
The zinc finger is a common structural motif in many protein DNA binding domains. It is found in roughly 3%(!) of all proteins and performs a diverse range of functions not limited to enhancing or inhibiting one specific gene.
