https://www.alphaknockout.com Mouse Mcf2 Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Mcf2 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Mcf2 gene (NCBI Reference Sequence: NM_001289731 ; Ensembl: ENSMUSG00000031139 ) is located on Mouse chromosome X. 28 exons are identified, with the ATG start codon in exon 1 and the TAG stop codon in exon 28 (Transcript: ENSMUST00000063507). Exon 8 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Mcf2 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-87N13 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 and hemizygous null mice are viable, fertile and behaviorally normal, exhibit normal gonad and brain development and neuronal migration, but show a significant reduction of basal dendritic length in distinct subpopulations of cortical pyramidal neurons. Exon 8 starts from about 24.18% of the coding region. The knockout of Exon 8 will result in frameshift of the gene. The size of intron 7 for 5'-loxP site insertion: 3430 bp, and the size of intron 8 for 3'-loxP site insertion: 632 bp. The size of effective cKO region: ~634 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(7134bp) | A(25.23% 1800) | C(21.35% 1523) | T(34.65% 2472) | G(18.77% 1339) 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.
