https://www.alphaknockout.com Mouse Rint1 Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Rint1 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Rint1 gene (NCBI Reference Sequence: NM_177323 ; Ensembl: ENSMUSG00000028999 ) is located on Mouse chromosome 5. 15 exons are identified, with the ATG start codon in exon 1 and the TAA stop codon in exon 15 (Transcript: ENSMUST00000030852). 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 Rint1 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-14F17 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 mutant allele exhibit early embryonic lethality. Mice heterozygous for a mutant allele exhibit premature death with a life span of 24 months and increased multiple tumor incidence. Exon 4 starts from about 11.53% 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: 6107 bp, and the size of intron 4 for 3'-loxP site insertion: 4473 bp. The size of effective cKO region: ~742 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(7242bp) | A(27.09% 1962) | C(20.33% 1472) | T(30.93% 2240) | G(21.65% 1568) 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.
