Mouse Cracr2a Knockout Project (CRISPR/Cas9)
Objective: To create a Cracr2a knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering.
Strategy summary: The Cracr2a gene (NCBI Reference Sequence: NM_001033464 ; Ensembl: ENSMUSG00000061414 ) is located on Mouse chromosome 6. 7 exons are identified, with the ATG start codon in exon 2 and the TAA stop codon in exon 7 (Transcript: ENSMUST00000071563). Exon 2~5 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:
Exon 2 starts from the coding region. Exon 2~5 covers 70.22% of the coding region. The size of effective KO region: ~7703 bp. The KO region does not have any other known gene.

Note: The 2000 bp section upstream of Exon 2 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 upstream of Exon 2 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.
