Mouse Bet1 Knockout Project (CRISPR/Cas9)

Objective: To create a Bet1 knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering.

Strategy summary: The Bet1 (NCBI Reference Sequence: NM_009748 ; Ensembl: ENSMUSG00000032757 ) is located on Mouse 6. 4 exons are identified, with the ATG start codon in exon 1 and the TGA stop codon in exon 4 (Transcript: ENSMUST00000049166). Exon 1~4 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 0.28% of the coding region. Exon 1~4 covers 100.0% of the coding region. The size of effective KO region: ~8910 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. Tandem repeats are found in the dot plot matrix. The gRNA site is selected outside of these tandem repeats.

Overview of the GC Content Distribution (up) Window size: 300 bp

Sequence 12

Summary: Full Length(2000bp) | A(28.4% 568) | C(23.05% 461) | T(30.5% 610) | G(18.05% 361)

Note: The 2000 bp section upstream of start codon 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.

Overview of the GC Content Distribution (down) Window size: 300 bp

Sequence 12

Summary: Full Length(2000bp) | A(28.85% 577) | C(16.7% 334) | T(35.7% 714) | G(18.75% 375)

Note: The 2000 bp section downstream of stop codon 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.
