Mouse Epb42 Knockout Project (CRISPR/Cas9)
Objective: To create a Epb42 knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering.
Strategy summary: The Epb42 gene (NCBI Reference Sequence: NM_013513 ; Ensembl: ENSMUSG00000023216 ) is located on Mouse chromosome 2. 13 exons are identified, with the ATG start codon in exon 1 and the TAA stop codon in exon 13 (Transcript: ENSMUST00000102490). Exon 2~5 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: Homozygotes for a targeted null mutation exhibit erythrocytic abnormalities including mild spherocytosis, altered ion transport, and dehydration.
Exon 2 starts from about 0.53% of the coding region. Exon 2~5 covers 31.07% of the coding region. The size of effective KO region: ~5547 bp. The KO region does not have any other known gene.

Note: The 1985 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.
