Caption Schematic diagram of targeting strategy. (A) The targeting construct for generation of the Ptk2tm1Itl allele contains the exon 21 (red box) with R454 point mutation and a Neo cassette (blue box) flanked by FLP recombinase target (FRT) sites (green triangles). The 9.7 kb region used to construct the targeting vector was subcloned from a C57BL/6 BAC clone. The region was designed such that the long homology arm extends ~8.0 kb 3' to the Neo cassette. The two FRT flanked Neo cassette is inserted ~0.5 kb downstream of the point mutated region in exon 21. The short homology arm extends 1.6 kb 5' to the Neo cassette. An A to G point mutation in exon 21 was generated by PCR mutagenesis to change codon lysine-454 to arginine (R454). The R454 mutation in FAK kinase domain blocks ATP binding resulting in a kinase-inactive FAK protein. (B) Neo cassette removal from Ptk2tm1Itl/Ptk2+ mice. When two FRT sites are present, the FLP enzyme creates double-stranded DNA breaks, exchanges FRT site ends, reattaches the exchanged strands which leads Neo cassette deletion between the two FRT sites. By crossing Ptk2tm1Itl/Ptk2+ mice with transgenic FlpE mice (Jax #003800), the Neo cassette was removed, generating the Ptk2tm1.1Itl allele.
