https://www.alphaknockout.com Mouse Egflam Knockout Project (CRISPR/Cas9) Objective: To create a Egflam knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Egflam gene (NCBI Reference Sequence: NM_001289496 ; Ensembl: ENSMUSG00000042961 ) is located on Mouse chromosome 15. 23 exons are identified, with the ATG start codon in exon 1 and the TAA stop codon in exon 23 (Transcript: ENSMUST00000096494). Exon 2~3 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: Homozygous null mutants are viable and fertile under normal conditions. They exhibit abnormal photoreceptor ribbon synapses, resulting in alteration in synaptic signal transmission and visual function. Exon 2 starts from about 3.21% of the coding region. Exon 2~3 covers 6.36% of the coding region. The size of effective KO region: ~1952 bp. The KO region does not have any other known gene.

No significant tandem repeat is found in the dot plot matrix. So this region is suitable for PCR screening or sequencing analysis. Overview of the Dot Plot (down) Window size: 15 bp Forward Reverse Complement Sequence 12 Note: The 2000 bp section downstream of Exon 3 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.

No significant high GC-content region is found. So this region is suitable for PCR screening or sequencing analysis. Overview of the GC Content Distribution (down) Window size: 300 bp Sequence 12 Summary: Full Length(2000bp) | A(27.05% 541) | C(23.9% 478) | T(28.7% 574) | G(20.35% 407) Note: The 2000 bp section downstream of Exon 3 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.
