Mouse Bcas1 Knockout Project (CRISPR/Cas9)
Objective: To create a Bcas1 knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering.
Strategy summary: The Bcas1 gene (NCBI Reference Sequence: NM_029815 ; Ensembl: ENSMUSG00000013523 ) is located on Mouse chromosome 2. 13 exons are identified, with the ATG start codon in exon 2 and the TAA stop codon in exon 13 (Transcript: ENSMUST00000013667). Exon 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: Mice homozygous for a knock-out allele exhibit hypomyelination, decreased prepulse inhibition suggestive of schizophrenia-like symptoms, a tendency toward reduced anxiety-like behaviors, and upregulation of inflammation-related genes in the brain.
Exon 4 starts from about 8.0% of the coding region. Exon 4 covers 30.28% of the coding region. The size of effective KO region: ~575 bp. The KO region does not have any other known gene.

Note: The 2000 bp section upstream of Exon 4 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 Exon 4 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.
