https://www.alphaknockout.com Mouse Sipa1 Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Sipa1 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Sipa1 gene (NCBI Reference Sequence: NM_001164481 ; Ensembl: ENSMUSG00000056917 ) is located on Mouse chromosome 19. 18 exons are identified, with the ATG start codon in exon 4 and the TGA stop codon in exon 18 (Transcript: ENSMUST00000071857). Exon 8~11 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Sipa1 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-25C21 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: Homozygous null mice display chronic myelocytic leukemia in either the chronic phase or blast crisis. Exon 8 starts from about 36.87% of the coding region. The knockout of Exon 8~11 will result in frameshift of the gene. The size of intron 7 for 5'-loxP site insertion: 362 bp, and the size of intron 11 for 3'-loxP site insertion: 1125 bp. The size of effective cKO region: ~2224 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(8655bp) | A(23.52% 2036) | C(26.54% 2297) | T(23.03% 1993) | G(26.91% 2329) 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.
