Mouse Trnp1 Conditional Knockout Project (CRISPR/Cas9)
Objective: To create a Trnp1 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering.
Strategy summary: The Trnp1 gene (NCBI Reference Sequence: NM_001081156 ; Ensembl: ENSMUSG00000056596 ) is located on Mouse chromosome 4. 2 exons are identified, with the ATG start codon in exon 1 and the TGA stop codon in exon 1 (Transcript: ENSMUST00000125541). 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 Trnp1 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-392E4 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 starts from about 100% of the coding region. The knockout of Exon 1 will result in frameshift of the gene. The size of effective cKO region: ~840 bp. The cKO region does not have any other known gene.

Overview of the Dot Plot Window size: 10 bp
Forward Reverse Complement
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(6923bp) | A(21.51% 1489) | C(25.13% 1740) | T(25.16% 1742) | G(28.2% 1952)
Note: The sequence of homologous arms and cKO region is analyzed to determine the GC content. Significant high GC-content regions are found. It may be difficult to construct this targeting vector.
