How does the mosaic flp/frt system work

WebMosaic analysis with a repressible cell marker, or MARCM, is a genetics technique for creating individually labeled homozygous cells in an otherwise heterozygous Drosophila melanogaster. [1] It has been a crucial tool in studying the development of the Drosophila nervous system. 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.

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 ...
