Cre is a site-specific DNA recombinase that is useful for either targeted excision or activation of a desired gene in the genome in a temporally and spatially controlled manner. Cre-based recombination strategies also permit the design of precise chromosome translocations, deletions and duplications, which facilitate the genetic manipulation of the eukaryotic genome.
