Mouse Kdm1b Knockout Project (CRISPR/Cas9)
Objective: To create a Kdm1b knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering.
Strategy summary: The Kdm1b gene (NCBI Reference Sequence: NM_172262 ; Ensembl: ENSMUSG00000038080 ) is located on Mouse chromosome 13. 21 exons are identified, with the ATG start codon in exon 2 and the TAA stop codon in exon 21 (Transcript: ENSMUST00000037025). Exon 2~6 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: Homozygous null mice of both sexes are viable, grossly normal and male mice are fertile; however, heterozygous progeny of homozygous null mothers display severe placental defects, embryonic growth impairment, neural tube defects and pericardial edema, and do not survive past E10.5.
Exon 2 starts from the coding region. Exon 2~6 covers 21.55% of the coding region. The size of effective KO region: ~5833 bp. The KO region does not have any other known gene.

Note: The 2000 bp section upstream of Exon 2 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 upstream of Exon 2 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.
