| Caption | Generation of conditional Xpatm1Gvh allele. A) Schematic representation of the wild-type (Wt) mouse Xpa locus (exon 2 to 6), the targeting construct, the conditional Xpa allele, and the conditional Xpa allele following Cre-recombinase mediated inactivation. In addition, the knock out allele with a neomycin (NEO) marker cassette, as present in the non-conditional Xpa mouse model is shown. In the conditional construct, exon 4 was fused in frame to the mouse Xpa cDNA (containing the remaining coding sequence and including a synthetic polyA sequence), followed by a PGK promoter-driven hygromycin (HYGRO) selectable marker gene. LoxP sites were introduced in intron 3 and downstream of the hygromycin marker to allow Cre-mediated excision of the cDNA and hygromycin marker gene, yielding an Xpa allele lacking exon 4, known to act as a null allele. A LacZ-GFP fusion marker gene, preceded by a splice acceptor (SA) and an internal ribosomal entry (IRES) was included to allow visualization of inactivation of the conditional Xpa allele. Open and gray boxes represent exon and cDNA sequences, respectively. The splice acceptor-Murfi cassette ensures proper splicing and translational stops in all frames respectively when the Xpa gene is knocked out. | ||||
