Mouse Ndufb4 Knockout Project (CRISPR/Cas9)
Objective: To create a Ndufb4 knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering.
Strategy summary: The Ndufb4 gene (NCBI Reference Sequence: NM_026610 ; Ensembl: ENSMUSG00000022820 ) is located on Mouse chromosome 16. 3 exons are identified, with the ATG start codon in exon 1 and the TAA stop codon in exon 3 (Transcript: ENSMUST00000023514). Exon 1~3 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:
Exon 1 starts from about 0.26% of the coding region. Exon 1~3 covers 100.0% of the coding region. The size of effective KO region: ~6698 bp. The KO region does not have any other known gene.

Forward Reverse Complement
Sequence 12
Note: The 2000 bp section upstream of start 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 downstream of stop codon 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.
