Mouse Hexim2 Conditional Knockout Project (CRISPR/Cas9)
Objective: To create a Hexim2 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering.
Strategy summary: The Hexim2 gene (NCBI Reference Sequence: NM_027658 ; Ensembl: ENSMUSG00000043372 ) is located on Mouse chromosome 11. 3 exons are identified, with the ATG start codon in exon 2 and the TGA stop codon in exon 3 (Transcript: ENSMUST00000062530). Exon 3 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Hexim2 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-133L3 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 3 covers 93.29% of the coding region. Start codon is in exon 2, and stop codon is in exon 3. The size of intron 2 for 5'-loxP site insertion: 4045 bp. The size of effective cKO region: ~2440 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. 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(7376bp) | A(25.41% 1874) | C(24.62% 1816) | T(22.94% 1692) | G(27.03% 1994)
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.
