Nkx2-1^{tm2.1(flpo)Zjh}

The targeting vector is designed to insert an internal ribosome entry site (IRES) fused to flpo recombinase gene (a codon-optimized FLPe gene modified for translation in mammalian cells and higher recombination efficiency in cells and in mice), followed by a loxP-flanked neo cassette, downstream of the stop codon of the gene. Cre-mediated recombination removed the floxed neo cassette. (J:235123)
