Mouse Magi2 Conditional Knockout Project (CRISPR/Cas9)

Objective: To create a Magi2 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering.

Strategy summary: The Magi2 (NCBI Reference Sequence: NM_001170746 ; Ensembl: ENSMUSG00000040003 ) is located on Mouse 5. 23 exons are identified, with the ATG start codon in exon 1 and the TAG stop codon in exon 23 (Transcript: ENSMUST00000088516). Exon 12 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Magi2 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-425D14 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 neonatal death and hippocampal neurons with altered dendritic spine morphology. Homozygotes for a different null allele die neonatally due to anuria and podocyte anomalies. Mice lacking all three isoforms develop proteinuria, podocytopathy and die of renal failure.

Exon 12 starts from about 54.3% of the coding region. The knockout of Exon 12 will result in frameshift of the gene. The size of intron 11 for 5'-loxP site insertion: 6016 bp, and the size of intron 12 for 3'-loxP site insertion: 9058 bp. The size of effective cKO region: ~690 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(7190bp) | A(29.6% 2128) | C(21.29% 1531) | T(27.69% 1991) | G(21.42% 1540)

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.
