WebFeb 1, 2024 · The beauty of the FLP/FRT system is that recombination in flies is now inducible, site-specific, and highly efficient. FLP is a sequence-specific recombinase that mediates recombination by binding two conserved, short FRT sequences, and catalyzing … 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. We have introduced dom -
WebAug 21, 2024 · In this system flippase (FLP)-mediated recombination takes place between two flippase recognition target (FRT) sites positioned at identical loci and in the same orientation on homologous chromosomes. WebThe FLP/FRT-based genetic mosaic system depends on FLP-mediated mitotic recombination between FRTs residing in trans on homologous chromosomes 21,22,23. …
