Mouse Me1 Knockout Project (CRISPR/Cas9)
Objective: To create a Me1 knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering.
Strategy summary: The Me1 gene (NCBI Reference Sequence: NM_001198933 ; Ensembl: ENSMUSG00000032418 ) is located on Mouse chromosome 9. 14 exons are identified, with the ATG start codon in exon 1 and the TAA stop codon in exon 14 (Transcript: ENSMUST00000185374). Exon 2~3 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 spontaneous allele exhibit decreased body weight on a medium fat diet, altered cytoplasmic malic enzyme activity, and a male-specific reduction in food intake on a high fat diet.
Exon 2 starts from about 1.15% of the coding region. Exon 2~3 covers 17.15% of the coding region. The size of effective KO region: ~2089 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. No significant tandem repeat is found in the dot plot matrix. So this region is suitable for PCR screening or sequencing analysis.
