Mouse Fgl1 Knockout Project (CRISPR/Cas9)

Objective: To create a Fgl1 knockout Mouse model (C57BL/6N) by CRISPR/Cas-mediated genome engineering.

Strategy summary: The Fgl1 gene (NCBI Reference Sequence: NM_145594 ; Ensembl: ENSMUSG00000031594 ) is located on Mouse chromosome 8. 8 exons are identified, with the ATG start codon in exon 2 and the TAG stop codon in exon 8 (Transcript: ENSMUST00000034003). Exon 3~4 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: Mice homozygous for one null allele exhibit increased body weight, white fat and gluconeogenesis, decreased circulating cholesterol, free fatty acid level and respiratory quotient, hyperglycemia, and impaired glucose tolerance. Mice homozygous for a second null allele display normal appearance with age-related onset of dermatitis.

Exon 3 starts from about 6.79% of the coding region. Exon 3~4 covers 36.84% of the coding region. The size of effective KO region: ~9439 bp. The KO region does not have any other known gene.

Sequence 12

Note: The 543 bp section upstream 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.
