WebMost mouse geneticists who work with Cre-lox mice probably are familiar with the FLP-FRT system. Like Cre, FLP is a tyrosine recombinase, but it originates from the yeast Saccharomyces cerevisiae, rather than from bacteriophage. In FLP-FRT, FLP is analogous to cre and FRT to loxP – FLP recognizes the FRT sites, and catalyzes recombination ... WebMar 1, 1999 · Mosaic analysis has been widely used in Drosophila for studying the functions of known genes, while the more recent introduction of the high efficiency FLP/FRT system (Golic and Lindquist 1989), together with means to effectively mark clones (Xu and Rubin 1993), has allowed the use of mosaic systems to screen for new mutants.

WebJun 9, 2024 · Mosaic analysis using the FLP/FRT system allows investigating the roles of essential genes during wing development in Drosophila melanogaster. This chapter describes the practical methods to isolate Notch signaling regulators by somatic mosaic screen. The fly stocks, cross schemes, and screen parameters are summarized. 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… WebMay 19, 2006 · The FLP-FRT system is similar to the C re-lox system and is becoming more frequently used in mouse-based research.
