Mouse P2rx4 Knockout Project (CRISPR/Cas9)
Objective: To create a P2rx4 knockout Mouse model (C57BL/6N) by CRISPR/Cas-mediated genome engineering.
Strategy summary: The P2rx4 gene (NCBI Reference Sequence: NM_011026 ; Ensembl: ENSMUSG00000029470 ) is located on Mouse chromosome 5. 12 exons are identified, with the ATG start codon in exon 1 and the TGA stop codon in exon 12 (Transcript: ENSMUST00000031429). Exon 2~4 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: Homozygous mutation of this gene results in hypertension, abnormal artery morphology, abnormal nitric oxide homeostasis, and impaired flow induced vascular remodeling and vasodilation.
Exon 2 starts from about 11.6% of the coding region. Exon 2~4 covers 25.17% of the coding region. The size of effective KO region: ~4175 bp. The KO region does not have any other known gene.

Sequence 12
Note: The 2000 bp section upstream of Exon 2 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.

Note: The 556 bp section downstream 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.
