Mouse Ttyh2 Knockout Project (CRISPR/Cas9)
Objective: To create a Ttyh2 knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering.
Strategy summary: The Ttyh2 gene (NCBI Reference Sequence: NM_053273 ; Ensembl: ENSMUSG00000034714 ) is located on Mouse chromosome 11. 14 exons are identified, with the ATG start codon in exon 1 and the TAG stop codon in exon 14 (Transcript: ENSMUST00000045779). 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 8.15% of the coding region. Exon 2 covers 10.84% of the coding region. The size of effective KO region: ~173 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. 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.
