Mouse Pdlim1 Conditional Knockout Project (CRISPR/Cas9)
Objective: To create a Pdlim1 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering.
Strategy summary: The Pdlim1 gene (NCBI Reference Sequence: NM_016861 ; Ensembl: ENSMUSG00000055044 ) is located on Mouse chromosome 19. 7 exons are identified, with the ATG start codon in exon 1 and the TGA stop codon in exon 7 (Transcript: ENSMUST00000068439). Exon 2 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Pdlim1 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP24-352A5 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: Mice homozygous for a gene trap allele exhibit enhanced platelet response to GPVI agonists and thrombosis.
Exon 2 starts from about 9.89% of the coding region. The knockout of Exon 2 will result in frameshift of the gene. The size of intron 1 for 5'-loxP site insertion: 19284 bp, and the size of intron 2 for 3'-loxP site insertion: 2206 bp. The size of effective cKO region: ~652 bp. The cKO region does not have any other known gene.

Sequence 12
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.
Overview of the GC Content Distribution Window size: 300 bp
Sequence 12
Summary: Full Length(7152bp) | A(27.39% 1959) | C(22.04% 1576) | T(28.22% 2018) | G(22.36% 1599)
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.
