Mouse Acsm3 Conditional Knockout Project (CRISPR/Cas9)

Objective: To create a Acsm3 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering.

Strategy summary: The Acsm3 (NCBI Reference Sequence: NM_016870 ; Ensembl: ENSMUSG00000030935 ) is located on Mouse 7. 16 exons are identified, with the ATG start codon in exon 4 and the TGA stop codon in exon 16 (Transcript: ENSMUST00000106528). Exon 6 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Acsm3 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-202C8 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: Homozygous null mice are viable and fertile with normal kidney function and morphology and blood pressure similar to wild-type on either a regular or high salt diet.

Exon 6 starts from about 23.74% of the coding region. The knockout of Exon 6 will result in frameshift of the gene. The size of intron 5 for 5'-loxP site insertion: 4713 bp, and the size of intron 6 for 3'-loxP site insertion: 617 bp. The size of effective cKO region: ~708 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. No significant tandem repeat is found in the dot plot matrix. So this region is suitable for PCR screening or sequencing analysis.

Summary: Full Length(7208bp) | A(30.79% 2219) | C(18.84% 1358) | T(28.34% 2043) | G(22.03% 1588)

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.
