Mouse Btaf1 Knockout Project (CRISPR/Cas9)
Objective: To create a Btaf1 knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering.
Strategy summary: The Btaf1 gene (NCBI Reference Sequence: NM_001080706 ; Ensembl: ENSMUSG00000040565 ) is located on Mouse chromosome 19. 38 exons are identified, with the ATG start codon in exon 1 and the TGA stop codon in exon 38 (Transcript: ENSMUST00000099494). Exon 3~6 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: Embryos homozygous for a gene-trapped allele display growth retardation. Embryos homozygous for an ENU- induced allele show growth retardation, edema, abnormal blood circulation, myocardial trabeculae hypoplasia, and delayed head and brain development.
Exon 3 starts from about 2.51% of the coding region. Exon 3~6 covers 10.1% of the coding region. The size of effective KO region: ~9442 bp. The KO region does not have any other known gene.

Sequence 12
Note: The 2000 bp section upstream of Exon 3 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.
