https://www.alphaknockout.com Mouse Ccdc183 Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Ccdc183 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Ccdc183 gene (NCBI Reference Sequence: NM_029859 ; Ensembl: ENSMUSG00000026940 ) is located on Mouse chromosome 2. 14 exons are identified, with the ATG start codon in exon 1 and the TAA stop codon in exon 14 (Transcript: ENSMUST00000028309). Exon 7~10 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Ccdc183 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-158L20 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 7 starts from about 41.64% of the coding region. The knockout of Exon 7~10 will result in frameshift of the gene. The size of intron 6 for 5'-loxP site insertion: 1363 bp, and the size of intron 10 for 3'-loxP site insertion: 676 bp. The size of effective cKO region: ~2225 bp. The cKO region does not have any other known gene.

Tandem repeats are found in the dot plot matrix. It may be difficult to construct this targeting vector. Overview of the GC Content Distribution Window size: 300 bp Sequence 12 Summary: Full Length(8725bp) | A(25.23% 2201) | C(27.0% 2356) | T(22.76% 1986) | G(25.01% 2182) 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.
