This conditional allele, in which exon 1 is flanked by loxP sequences, was derived from Yap1tm1a(KOMP)Mbp by flp recombinase-mediated excision of the lacZ reporter and the neomycin resistance cassette. Cre recombinase expression will result in a knockout mouse. 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:157064)
