Mouse Aktip Conditional Knockout Project (CRISPR/Cas9)
Objective: To create a Aktip conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering.
Strategy summary: The Aktip gene (NCBI Reference Sequence: NM_001302267 ; Ensembl: ENSMUSG00000031667 ) is located on Mouse chromosome 8. 11 exons are identified, with the ATG start codon in exon 3 and the TAA stop codon in exon 11 (Transcript: ENSMUST00000120213). Exon 4 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Aktip gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-149I24 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 hypomorphic allele exhibit impaired growth, skeletal and skin defects, abnormal heart tissue, and sterility.
Exon 4 starts from about 4.91% of the coding region. The knockout of Exon 4 will result in frameshift of the gene. The size of intron 3 for 5'-loxP site insertion: 1235 bp, and the size of intron 4 for 3'-loxP site insertion: 2670 bp. The size of effective cKO region: ~706 bp. The cKO region does not have any other known gene.

Note: The sequence of homologous arms and cKO region is aligned with itself to determine if there are tandem repeats. Tandem repeats are found in the dot plot matrix. It may be difficult to construct this targeting vector.
Overview of the GC Content Distribution Window size: 300 bp
Sequence 12
Summary: Full Length(7206bp) | A(25.08% 1807) | C(20.9% 1506) | T(30.16% 2173) | G(23.87% 1720)
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.
