Mouse Pcdhb5 Conditional Knockout Project (CRISPR/Cas9)
Objective: To create a Pcdhb5 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering.
Strategy summary: The Pcdhb5 gene (NCBI Reference Sequence: NM_053130 ; Ensembl: ENSMUSG00000063687 ) is located on Mouse chromosome 18. 1 exon is identified, with the ATG start codon in exon 1 and the TAA stop codon in exon 1 (Transcript: ENSMUST00000078271). Exon 1 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Pcdhb5 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-480H17 as template. Cas9, gRNA and targeting vector will be co-injected into fertilized eggs for cKO Mouse production. The pups will be genotyped by PCR followed by sequencing analysis. Note:
Exon 1 covers 100.0% of the coding region. Start codon is in exon 1, and stop codon is in exon 1. The size of effective cKO region: ~2409 bp. The cKO region does not have any other known gene.

Note: The sequence of homologous arms and cKO region 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.

Summary: Full Length(8376bp) | A(29.63% 2482) | C(19.72% 1652) | T(29.43% 2465) | G(21.22% 1777)
Note: The sequence of homologous arms and cKO region 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.
