Mouse Fam19a5 Knockout Project (CRISPR/Cas9)
Objective: To create a Fam19a5 knockout Mouse model (C57BL/6N) by CRISPR/Cas-mediated genome engineering.
Strategy summary: The Fam19a5 gene (NCBI Reference Sequence: NM_001252310 ; Ensembl: ENSMUSG00000054863 ) is located on Mouse chromosome 15. 4 exons are identified, with the ATG start codon in exon 1 and the TGA stop codon in exon 4 (Transcript: ENSMUST00000230414). 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:
Exon 2 starts from about 28.54% of the coding region. Exon 2 covers 37.88% of the coding region. The size of effective KO region: ~150 bp. The KO region does not have any other known gene.

Note: The 150 bp section 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.

Gene summary
Official Symbol Tafa5 provided by MGI Official Full Name TAFA chemokine like family member 5 provided by MGI Primary source MGI:MGI:2146182 See related Ensembl:ENSMUSG00000054863 Gene type protein coding RefSeq status REVIEWED Organism Mus musculus Lineage Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Glires; Rodentia; Myomorpha; Muroidea; Muridae; Murinae; Mus; Mus Also known as Tafa-5; Tara-5; Fam19a5 Summary This gene is a member of the TAFA family which is composed of five highly homologous genes that encode small secreted Expression proteins. These proteins contain conserved cysteine residues at fixed positions, and are distantly related to MIP-1alpha, a member of the CC-chemokine family. The TAFA proteins are predominantly expressed in specific regions of the brain, and are postulated to function as brain-specific chemokines or neurokines, that act as regulators of immune and nervous cells. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.
