Websuggest that either the frequency of FLP/FRT mediated mitotic recombination is much lower than that of intra-chromosomal flip-out, or that most of the lines that score positive for flip-out assay but negative for trans-FRT assay start their expression in post-mitotic neurons, or both. Figure 1. Genetic schemes to detect FLP enhancer trap activity. 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 ...
