... The loxP site consists of two 13 bp palindromic half-sites separated by an asymmetric 8 bp spacer that gives loxP its direction. The utility of targeting Cre mutants to altered RT sites is severely compromised if only pseudo-palindromic sites may be considered. This limitation has been addressed by ...

It is curious, however, that enrichment in closely linked h2h pairs is reported to be limited to mammals (Koyanagi et al. 2005); one would expect them to accumulate in all evolutionary lineages. We have therefore examined the evolution of closely linke ...

Zinc finger nuclease

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. By taking advantage of endogenous DNA repair machinery, these reagents can be used to precisely alter the genomes of higher organisms.
