Mouse Tmem43 Knockout Project (CRISPR/Cas9)
Objective: To create a Tmem43 knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering.
Strategy summary: The Tmem43 gene (NCBI Reference Sequence: NM_028766 ; Ensembl: ENSMUSG00000030095 ) is located on Mouse chromosome 6. 12 exons are identified, with the ATG start codon in exon 1 and the TGA stop codon in exon 12 (Transcript: ENSMUST00000032183). Exon 2~12 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: In a high-throughput screen, female homozygous mutant mice exhibited an increased anxiety-like response during open field activity testing when compared with their gender-matched wild-type littermates and the historical mean. Homozygous KO or certain codon substitution mutants don't affect heart function.
Exon 2 starts from about 1.08% of the coding region. Exon 2~12 covers 99.0% of the coding region. The size of effective KO region: ~9700 bp. The KO region does not have any other known gene.

Forward Reverse Complement
Sequence 12
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 stop codon 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 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.
