Mouse Pgam5 Conditional Knockout Project (CRISPR/Cas9)

Objective: To create a Pgam5 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering.

Strategy summary: The Pgam5 (NCBI Reference Sequence: NM_001163538 ; Ensembl: ENSMUSG00000029500 ) is located on Mouse 5. 6 exons are identified, with the ATG start codon in exon 1 and the TGA stop codon in exon 6 (Transcript: ENSMUST00000112505). Exon 2 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Pgam5 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-24E20 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: Homozygotes for a null allele show Parkinson-like movement, dopaminergic neuron loss, and altered mitochondrial homeostasis. Homozygotes for a different null allele are smaller, with males born at sub-Mendelian ratios. Macrophages show impaired inflammasome activation and IL-1beta secretion.

Exon 2 starts from about 21.88% of the coding region. The knockout of Exon 2 will result in frameshift of the gene. The size of intron 1 for 5'-loxP site insertion: 2386 bp, and the size of intron 2 for 3'-loxP site insertion: 1050 bp. The size of effective cKO region: ~679 bp. The cKO region does not have any other known gene.

Sequence 12

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.

Overview of the GC Content Distribution Window size: 300 bp

Sequence 12

Summary: Full Length(7179bp) | A(24.6% 1766) | C(23.42% 1681) | T(27.75% 1992) | G(24.24% 1740)

Note: The sequence of homologous arms and cKO region is analyzed to determine the GC content. Significant high GC-content regions are found. It may be difficult to construct this targeting vector.
