Mouse Crhbp Knockout Project (CRISPR/Cas9)
Objective: To create a Crhbp knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering.
Strategy summary: The Crhbp gene (NCBI Reference Sequence: NM_198408 ; Ensembl: ENSMUSG00000021680 ) is located on Mouse chromosome 13. 7 exons are identified, with the ATG start codon in exon 1 and the TGA stop codon in exon 7 (Transcript: ENSMUST00000221025). 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: Mice homozygous for disruptions in this gene display behavior indicative of increased anxiety. Male mice also show reduced food intake resulting in reduced growth between ages 7 and 15 weeks.
Exon 2 starts from about 8.49% of the coding region. Exon 2~6 covers 75.57% of the coding region. The size of effective KO region: ~7865 bp. The KO region does not have any other known gene.

Sequence 12
Note: The 330 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 downstream of Exon 6 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.
