WebThe yeast FLP recombinase and FRT sites Where and when mosaic clones are produced during development can be controlled by using tissue specific enhancers to drive recombinase enzymes that recognize specific sites engineered into the genome. The yeast 2 um plasmid encodes an enzyme known as the FLP recombinase In genetics, Flp-FRT recombination is a site-directed recombination technology, increasingly used to manipulate an organism's DNA under controlled conditions in vivo. It is analogous to Cre-lox recombination but involves the recombination of sequences between short flippase recognition target (FRT) sites by the recombinase flippase (Flp) derived from the 2 µ plasmid of baker's yeast Saccha… Webtissues, the FRT/FLP system has been shown to be func-tional in both male and female germ-line cells (Golic, 1991; Chou and Perrimon, 1992). The use of the FRT sequence to induce high frequency mosaicism for a particular gene requires that the FRT sequence be located closer to the cen - tromere than the gene of interest.
