Mouse Rras2 Knockout Project (CRISPR/Cas9)
Objective: To create a Rras2 knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering.
Strategy summary: The Rras2 gene (NCBI Reference Sequence: NM_025846 ; Ensembl: ENSMUSG00000055723 ) is located on Mouse chromosome 7. 6 exons are identified, with the ATG start codon in exon 1 and the TAA stop codon in exon 6 (Transcript: ENSMUST00000069449). Exon 3~5 will be selected as target site. Cas9 and gRNA will be co-injected into fertilized eggs for KO Mouse production. The pups will be genotyped by PCR followed by sequencing analysis. Note: Homozygote and heterozygote null mice are lymphopenic, resulting from diminished homeostatic proliferation and impaired T cell and B cell survival. Mice homozygous for a gene trap insertion exhibit retinal degeneration, and increased total body mass and total body fat.
Exon 3 starts from about 32.19% of the coding region. Exon 3~5 covers 54.08% of the coding region. The size of effective KO region: ~8729 bp. The KO region does not have any other known gene.

Forward Reverse Complement
Sequence 12
Note: The 1302 bp section upstream of Exon 3 is aligned with itself to determine if there are tandem repeats. Tandem repeats are found in the dot plot matrix. The gRNA site is selected outside of these tandem repeats.

Note: The 2000 bp section downstream of Exon 5 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.

Note: The 1302 bp section upstream of Exon 3 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.
