https://www.alphaknockout.com Mouse Pxdn Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Pxdn conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Pxdn gene (NCBI Reference Sequence: NM_181395 ; Ensembl: ENSMUSG00000020674 ) is located on Mouse chromosome 12. 23 exons are identified, with the ATG start codon in exon 1 and the TAG stop codon in exon 23 (Transcript: ENSMUST00000122328). Exon 11~13 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Pxdn gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP24-125H6 as template. Cas9, gRNA and targeting vector will be co-injected into fertilized eggs for cKO Mouse production. The pups will be genotyped by PCR followed by sequencing analysis. Note: Mice homozygous for an ENU-induced allele exhibit abnormal eye development with early-onset glaucoma and progressive retinal dysgenesis. Exon 11 starts from about 28.99% of the coding region. The knockout of Exon 11~13 will result in frameshift of the gene. The size of intron 10 for 5'-loxP site insertion: 2365 bp, and the size of intron 13 for 3'-loxP site insertion: 1048 bp. The size of effective cKO region: ~2511 bp. The cKO region does not have any other known gene.

No significant tandem repeat is found in the dot plot matrix. So this region is suitable for PCR screening or sequencing analysis. Overview of the GC Content Distribution Window size: 300 bp Sequence 12 Summary: Full Length(9011bp) | A(24.06% 2168) | C(22.96% 2069) | T(29.44% 2653) | G(23.54% 2121) Note: The sequence of homologous arms and cKO region is analyzed to determine the GC content. No significant high GC-content region is found. So this region is suitable for PCR screening or sequencing analysis.
