Mouse Elovl5 Knockout Project (CRISPR/Cas9)

Objective: To create a Elovl5 knockout Mouse model (C57BL/6N) by CRISPR/Cas-mediated genome engineering.

Strategy summary: The Elovl5 gene (NCBI Reference Sequence: NM_134255 ; Ensembl: ENSMUSG00000032349 ) is located on Mouse chromosome 9. 8 exons are identified, with the ATG start codon in exon 2 and the TGA stop codon in exon 8 (Transcript: ENSMUST00000034904). Exon 3 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: Mice homozygous for a gene trapped allele have defects in fatty acid synthesis in the liver that result in hepatic steatosis. Also, majority of female mice have defects in female fertility.

Exon 3 starts from about 6.58% of the coding region. Exon 3 covers 20.96% of the coding region. The size of effective KO region: ~188 bp. The KO region does not have any other known gene.

Sequence 12

Note: The 2000 bp section upstream of Exon 3 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 2000 bp section downstream 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 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.
