Mouse Dusp18 Knockout Project (CRISPR/Cas9)
Objective: To create a Dusp18 knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering.
Strategy summary: The Dusp18 gene (NCBI Reference Sequence: NM_173745 ; Ensembl: ENSMUSG00000047205 ) is located on Mouse chromosome 11. 2 exons are identified, with the ATG start codon in exon 2 and the TAA stop codon in exon 2 (Transcript: ENSMUST00000055931). Exon 2 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 about 0.18% of the coding region. Exon 2 covers 84.75% of the coding region. The size of effective KO region: ~478 bp. The KO region does not have any other known gene.

Sequence 12
Note: The 2000 bp section upstream of Exon 2 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.
