Mouse Hs2st1 Knockout Project (CRISPR/Cas9)
Objective: To create a Hs2st1 knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering.
Strategy summary: The Hs2st1 gene (NCBI Reference Sequence: NM_011828 ; Ensembl: ENSMUSG00000040151 ) is located on Mouse chromosome 3. 7 exons are identified, with the ATG start codon in exon 1 and the TGA stop codon in exon 7 (Transcript: ENSMUST00000043325). Exon 2 will be selected as target site. Cas9 and gRNA will be co-injected into fertilized eggs for KO Mouse production. The pups will be genotyped by PCR followed by sequencing analysis. Note: A mutation in this gene causes bilateral renal agenesis, bone defects, eye development abnormalities and cataracts in homozygous mice.
Exon 2 starts from about 11.7% of the coding region. Exon 2 covers 22.38% of the coding region. The size of effective KO region: ~239 bp. The KO region does not have any other known gene.

Note: The 2000 bp section upstream of Exon 2 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.
