https://www.alphaknockout.com Mouse Abca5 Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Abca5 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Abca5 gene (NCBI Reference Sequence: NM_147219 ; Ensembl: ENSMUSG00000018800 ) is located on Mouse chromosome 11. 39 exons are identified, with the ATG start codon in exon 2 and the TGA stop codon in exon 39 (Transcript: ENSMUST00000043961). Exon 2~3 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Abca5 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-198N23 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 a knock-out allele exhibit exophthalmos, tremors and collapse of the thyroid gland, and develop a dilated cardiomyopathy with large thrombi due to depression of the cardiac function. Severe edema, liver injury and premature death appear to be sensitive to genetic background. Exon 2 starts from about 0.04% of the coding region. The knockout of Exon 2~3 will result in frameshift of the gene. The size of intron 1 for 5'-loxP site insertion: 8228 bp, and the size of intron 3 for 3'-loxP site insertion: 1010 bp. The size of effective cKO region: ~2007 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(8507bp) | A(27.02% 2299) | C(18.94% 1611) | T(33.7% 2867) | G(20.34% 1730) 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.
