Mouse Gnai3 Knockout Project (CRISPR/Cas9)
Objective: To create a Gnai3 knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering.
Strategy summary: The Gnai3 gene (NCBI Reference Sequence: NM_010306 ; Ensembl: ENSMUSG00000000001 ) is located on Mouse chromosome 3. 9 exons are identified, with the ATG start codon in exon 1 and the TGA stop codon in exon 8 (Transcript: ENSMUST00000000001). 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: Mice homozygous for a knock-out allele exhibit normal basal cardiac function and beta-adrenergic sensitivity. Mice homozygous for a different knock-out allele exhibit enhanced T cell migration toward CXCR3 agonists.
Exon 2 starts from about 11.21% of the coding region. Exon 2~5 covers 44.44% of the coding region. The size of effective KO region: ~8075 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.

Note: The 2000 bp section downstream of Exon 5 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.
