https://www.alphaknockout.com Mouse Arhgap27 Knockout Project (CRISPR/Cas9) Objective: To create a Arhgap27 knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Arhgap27 gene (NCBI Reference Sequence: NM_001205236.1 ; Ensembl: ENSMUSG00000034255 ) is located on Mouse chromosome 11. 16 exons are identified, with the ATG start codon in exon 1 and the TGA stop codon in exon 16 (Transcript: ENSMUST00000107024). Exon 4~10 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 4 starts from about 48.25% of the coding region. Exon 4~10 covers 24.32% of the coding region. The size of effective KO region: ~2282 bp. The KO region does not have any other known gene.

No significant tandem repeat is found in the dot plot matrix. So this region is suitable for PCR screening or sequencing analysis. Overview of the Dot Plot (down) Window size: 15 bp Forward Reverse Complement Sequence 12 Note: The 124 bp section downstream of Exon 10 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(124bp) | A(19.35% 24) | C(23.39% 29) | T(20.16% 25) | G(37.1% 46) Note: The 124 bp section downstream of Exon 10 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.
