https://www.alphaknockout.com Mouse Gsta4 Knockout Project (CRISPR/Cas9) Objective: To create a Gsta4 knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Gsta4 gene (NCBI Reference Sequence: NM_010357 ; Ensembl: ENSMUSG00000032348 ) is located on Mouse chromosome 9. 7 exons are identified, with the ATG start codon in exon 2 and the TAG stop codon in exon 7 (Transcript: ENSMUST00000034903). Exon 2~6 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 disruptions in this gene display increased sensitivity to oxidative stress, increased alanine and aspartate transaminase levels, increased susceptibility to bacterial infection, reduced litter size, and impaired glucose tolerance. Exon 2 starts from the coding region. Exon 2~6 covers 81.98% of the coding region. The size of effective KO region: ~9663 bp. The KO region does not have any other known gene.

Tandem repeats are found in the dot plot matrix. The gRNA site is selected outside of these tandem repeats. Overview of the Dot Plot (down) Window size: 15 bp Forward Reverse Complement Sequence 12 Note: The 1124 bp section downstream of Exon 6 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.

No significant high GC-content region is found. So this region is suitable for PCR screening or sequencing analysis. Overview of the GC Content Distribution (down) Window size: 300 bp Sequence 12 Summary: Full Length(1124bp) | A(23.93% 269) | C(20.28% 228) | T(33.19% 373) | G(22.6% 254) Note: The 1124 bp section downstream of Exon 6 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.
