The mutant allele has, from 5' to 3', an FRT site, an En2 splice acceptor cassette containing IRES, beta-galactosidase and polyA sequence, a loxP site, human beta-actin promoter, SV40 polyA, a second FRT site, and a second loxP site inserted upstream of exon 6. A third loxP-site is inserted downstream of exon 8. Flp-mediated recombination removed the FRT-flanked neo cassette and En2 splice acceptor leaving exons 6 through 8 floxed. Further information on targeting strategies used for this and other IKMC alleles can be found at http://www.informatics.jax.org/mgihome/nomen/IKMC_schematics.shtml. (J:157065)
