A zinc finger motif is an element of proteins that can specifically recognize and bind to DNA. Because they contain multiple cysteine residues, zinc finger motifs possess redox properties. Ionizing radiation generates a variety of free radicals in organisms. Zinc finger motifs, therefore, may be a target of ionizing radiation. The effect of gamma radiation on the zinc finger motifs in transcrip...

Genome editing aims to revolutionise plant breeding and could assist in safeguarding the global food supply. The inclusion of a 12–40 bp recognition site makes mega nucleases first tools utilized for genome generation gene-editing tools. Zinc finger (ZFNs) are second technique, because they create double-stranded breaks, more dependable effective. ZFNs were original designed nuclease-based appr...

Genetic modification has long provided an approach for "reverse genetics", analyzing gene function and linking DNA sequence to phenotype. However, traditional genome editing technologies have not kept pace with the soaring progress of the genome sequencing era, as a result of their inefficiency, time-consuming and labor-intensive methods. Recently, invented genome modification technologies, suc...

Site-specific and rare cutting nucleases are valuable tools for genome engineering. The generation of double-strand DNA breaks (DSBs) promotes homologous recombination in eukaryotes and can facilitate gene targeting, additions, deletions, and inactivation. Zinc finger nucleases have been used to generate DSBs and subsequently, for genome editing but with low efficiency and reproducibility. The ...

One simple and widespread method to create engineered zinc fingers targeting the desired DNA sequences is to modularly assemble multiple finger modules pre-selected to recognize each DNA triplet. However, it has become known that a sufficient DNA binding affinity is not always obtained. In order to create successful zinc finger proteins, it is important to understand the context-dependent contr...
